Contract amendments
Overview
The EOR contract amendment API lets you update contract terms through a structured approval process that follows predefined compliance rules.
An amendment is a change to one or more contract terms, referred to as data points, such as employment type, job title, scope, or salary. Instead of modifying the original contract document, the amendment is issued as a separate addendum to the employment agreement.
The contract entity in the database, including its ID, remains the same. Only specific values are updated with a new effective date.
Amendment flows
Amendments can be initiated by you or by Deel. The steps an amendment goes through differ depending on who initiates it.
Client-initiated amendments
After confirmation:
- If the change is applied immediately, the API response includes the updated status.
- If the change requires approval, Deel reviews it and sends it to the employee for signing.
Deel-initiated amendments
Review and decide
Accept with the Accept amendment endpoint or cancel with the Cancel amendment endpoint.
When Deel creates amendments
Deel may create amendments in these cases:
- At your request when a change requires Deel involvement.
- To ensure compliance when a contract update is needed to meet legal requirements.
- For restricted changes when updates are only available through admin amendments.
Webhook events
Webhooks provide automatic updates on amendment status changes.
Amendment types
Each amendment has a type that determines its processing flow. The type is based on the amendment settings and the data points being amended.
INSTANT: Activated immediately after confirmation. No Deel review or employee signature required.AUTOMATED: Activated once the employee signs. Deel review not required.LEGALorOPS: Requires Deel review because at least one data point requires internal review. After Deel completes the review, the amendment is sent to the employee for signature.DISABLED: Contains at least one data point that is restricted from being changed.CUSTOM: Manually created by a Deel admin.
If at least one data point requires Deel review (LEGAL or OPS), the amendment type is set
to match. All data points follow the same review and activation flow.
Example: Instant amendment
In this Germany example, both holidays and timeOffType changes are instant.
Example: Legal amendment
For Greece, the same data points require Deel review because one item has the LEGAL type.
Retrieve contract information
To retrieve available amendment settings, you first need the contract ID.
Use the List of contracts endpoint to retrieve your contracts. You can filter and sort the list to find the correct contract_id.
Retrieve amendment settings
Once you have a contract ID, use it to retrieve valid amendment settings using the Get Amendment validation settings endpoint.
These settings are based on the contract and country-specific rules.
The validation settings endpoint accepts an optional employment_state query parameter to provide more accurate validation rules based on the intended state or region.
Use this when you need to amend the employment_state and need validation rules specific to the new state.
For example, hourly rate minimum wages can vary by state. If not provided, the current contract’s employment state is used for validation rules.
Example with query parameters
Example response
Amendment settings structure
The response for amendment settings includes a list of configurable contract fields. Each field is described by a data_point object that defines how it can be changed.
Key elements
- Each
data_pointrepresents an attribute in the contract that may be amended. - The
requiresobject defines conditions that must be met for the change to be allowed. All fields inrequiresmust match either the current contract or the amendment request. - Numeric fields include
minandmaxconstraints. possible_optionslists the allowed values for the data point.is_editableindicates if the field can be updated.additional_detailsmay include validation notes or business constraints.- Date fields can include
min_dateandmax_date, formatted asYYYY-MM-DD.
Rule examples
Require a field in the contract or request
You can only apply this rule if the contract or amendment request includes contract_term: "DEFINITE".
Employment type restriction
You can set employment_type to FULL_TIME only if contract_term is INDEFINITE.
Numeric constraints
This rule allows minimum and maximum values when employment_type is FULL_TIME.
External validation
This rule indicates that complete validation requires calling the validate amendment endpoint.
When external_validation: true, you can either call the validate endpoint for server-side validation or skip validation and let the create/update endpoints return validation errors.
Amendment effective date
The effective date is when the amendment becomes active. It defines when changes take effect and appear in payroll, invoices, or other downstream processes.
Different amendment fields trigger different business logic. Based on what you are changing, Deel dynamically calculates a valid effective date range.
Use the Effective Date Limitations endpoint to retrieve the valid effective date limits for a specific amendment.
Fetching effective date limits
You must fetch the effective date limitations:
- Immediately after creating or updating an amendment.
- Before setting or submitting the effective date.
- Before confirming the amendment if any changes were made after fetching the last effective date.
The valid effective date range is based on the specific changes in the amendment. Always fetch the date limits only after all changes to the amendment are finalized.
Status behavior by effective date
Amendments in upcoming status do not affect payroll, invoicing, or contract terms until they
are activated by Deel’s internal job on the effective date.
High-level flow
The diagram below shows how the effective date influences the amendment lifecycle.
UI behavior
When you fetch effective date limitations, the response includes flags that guide you in rendering the field in your UI.
If your use case involves applying an automatic default effective date, such as aligning it with the start of the payroll cycle, hiding the field might improve user experience.
Effective date validation rules
The validation logic for effective dates ensures that all amendments respect configuration limits.
Validation runs at two points:
- On create or update when you send the effective date in the request payload.
- On confirmation when the effective date is always validated, regardless of draft status.
Create a draft amendment
Create a new draft amendment by specifying the contract_id. You can include all, some, or none of the data points you plan to amend.
This allows you to start with a basic amendment and add more details later.
Empty amendment
Amendment with data points
Update existing draft amendment
Update an existing draft amendment by including the amendment_id returned when the amendment was created.
You can add additional data points, modify existing ones, or set the effective date. This endpoint allows you to build your amendment incrementally.
Updating an amendment replaces its full set of data points. Each update request must contain all the data points you want to keep, not just the one you are changing. If you only send the newly updated data point, any previously saved data points that are not included will be removed from the amendment.
Amendment validation approaches
You have these options for validating amendment data points:
- Client-side validation: Use the validation rules from the amendment settings endpoint to validate fields before submission.
- Server-side validation: Use the validate amendment endpoint to validate fields before submission.
- Hybrid approach: Use client-side validation for basic fields and server-side validation for complex fields with
external_validation: true. - No pre-validation: Skip validation and let the create/update endpoints return validation errors.
The amendment submission endpoint always performs validation and returns errors, so pre-validation is optional.
However, for fields with external_validation: true, you may want to validate beforehand to provide better user experience or to perform AI job scope checks and job categorization.
Hybrid approach
The hybrid approach combines both validation methods for optimal performance and user experience:
- Use client-side validation for fields with
external_validation: falseto provide immediate feedback. - Use server-side validation for fields with
external_validation: trueto get complete validation.
Validate amendment data points
Use the validate amendment endpoint to validate amendment data points before submission.
The /validate endpoint is deprecated. Use validate amendment for new implementations.
Response format
The response includes validation results with field-specific error mapping.
Error response with field mapping
When validation fails, errors include a field parameter for easy frontend integration.
AI job scope check and job categorization
AI review check
When a job title or scope amendment is created or updated, an AI review check is triggered to ensure the new job title or scope aligns with the existing job description and responsibilities.
Trigger the AI review check
Call the validate amendment endpoint for the AI review check to be performed before creating or updating the job title or scope amendment.
Example: Validate job title and scope
Response:
Example: Create or update amendment with AI scope check ID
Job categorization with AI recommendations
Job categorization is only available for specific countries. Every time a job title is amended, an AI job categorization is triggered to classify the new job title into a predefined job category and code.
You can trigger the validate amendment endpoint for the AI job categorization to be performed before creating or updating the job title amendment.
You can submit the amendment regardless of the AI job categorization outcome. If the AI job categorization fails, the amendment will be flagged for manual review by Deel’s internal team.
You will get job_categorization_log_id, job_code, and job_category when using the validate amendment endpoint if the AI job categorization succeeds. Send these values in the create or update amendment request to avoid manual review.
Example: Validate job title for categorization
Response:
Example: Update amendment with job categorization
Combined AI check and job categorization
When you trigger the validate amendment endpoint for job title amendments:
- In countries where job categorization is supported, both AI check and job categorization run. You must send
ai_scope_check_public_idandjob_categorization_log_idtogether withjob_codeandjob_categoryto avoid manual review. - In countries where job categorization is not supported, only AI check runs.
Seniority ID
To amend seniority_id:
- Retrieve the list of available levels using the Get Seniority List endpoint.
- Include the selected
seniority_idin your amendment request.
Effective date limitations
Validation errors and disabled amendments
Amendment requests can fail if validation rules are not met. In these cases, the API returns an error response that includes details about validation errors and disabled data points.
Standard error format
All error responses follow a consistent format, making them easier to interpret and integrate.
Each response includes a code and a message field, while the field attribute remains optional.
Mandatory fields
Optional fields
Common amendment error codes
Error response examples
Request validation errors
These errors occur when the request payload fails general validation checks.
General amendment errors
These errors indicate that the amendment request cannot proceed due to one or more issues.
Amendment field validation errors
These errors appear when specific fields are invalid or disabled for the requested amendment.
Amendment processing failed errors
These errors occur when an amendment cannot be updated or confirmed.
Amendment statuses
Amendments pass through multiple statuses from creation to completion. These statuses are returned in an array within the API response.
Check the most recent status to determine the amendment’s current state.
Amendment status structure
Amendment statuses are hierarchical and can be read at multiple levels of detail. Each status has two key properties:
NAME: Machine-readable identifierFRIENDLY_NAME: Human-readable label
Status stages
Draft stage
Amendments that are still being prepared and can be modified.
Preparing documents stage
Statuses related to document preparation and internal review. Documents are being created, reviewed, or paused for input before signatures can begin. No action required by you in this case, fetch the amendments to get the latest status.
Statuses
Signature stage
These statuses indicate the amendment is awaiting or in the process of being signed.
Statuses
Active or upcoming stage
Statuses when an amendment is in effect or scheduled for the future.
Cancelled, rejected, or void stage
Statuses for amendments that were canceled, rejected, or voided.
How to read amendment statuses
Amendment statuses are structured in a hierarchical format, where each level provides increasing detail about the amendment’s progress.
Parent phase
Represents the overall stage of the amendment, for example PREPARING_DOCUMENTS. Indicates the broad area of progress.
Sub-step
A more specific action within the parent phase, for example PREPARING_DOCUMENTS.AMENDMENT_REQUESTED.
Detailed checkpoint
Provides the most detailed level of the amendment’s status, for example PREPARING_DOCUMENTS.AMENDMENT_REQUESTED.SOW.PENDING_DOCUMENT_SUBMIT.
By reading an amendment status from left to right, you can move from the broad phase to the precise checkpoint, making it easy to understand exactly where the amendment stands.
Why this matters
- Each nested level gives increasing detail about the amendment’s progress.
- The high-level phase always represents the current overall state of the amendment.
- Sub-steps and detailed checkpoints record the lifecycle progression. This is useful for auditing, troubleshooting, and tracking how the amendment evolved.
The parent status is the single source of truth for the amendment’s current state. The history should not be used to infer the current status.
Example status array
In this example:
- The amendment is in the
PREPARING_DOCUMENTSphase. - The request is logged as
PREPARING_DOCUMENTS.AMENDMENT_REQUESTED. - The amendment is waiting for Deel review. Further actions are required before it can proceed.
Confirm an amendment
To confirm a draft amendment, use the contract_id and amendment_id. Only draft amendments can be confirmed.
After confirmation, the flow depends on the amendment type. If the type is instant, the amendment becomes active immediately. If it requires signatures, Deel or the employee must approve it first.
Cancel an amendment
To cancel an amendment, use the contract_id and amendment_id. You can cancel an amendment any time before the employee signs it.
After cancellation, you can delete it if needed.
Download an amendment PDF
Retrieve the download URL for the Statement of Work (Employee Agreement, EA) of a confirmed amendment. The URL is available only after the amendment is confirmed and the contract is in progress.
Accept an amendment
Use this endpoint to accept an amendment submitted by a Deel admin.
After acceptance, the amendment either becomes active immediately or moves to the signature step, depending on its type.
Sign an approved amendment
An employee can sign an amendment approved by both the client and admin. After signing, the amendment becomes active.

Custom amendment items
Custom amendment items are used when you request changes that:
- Involve data points not supported or not available in the standard amendment flow.
- Modify general employment agreement wording for active contracts.
- Include other ad-hoc or unique change requests not covered by standard items.
Once the amendment is confirmed, these custom items are reviewed by internal Deel teams.
Lifecycle and behavior
- Custom amendment items are part of an amendment, just like standard amendment items, and follow the same overall amendment lifecycle:
created → confirmed → reviewed - Custom items also have a separate internal lifecycle. They have their own statuses and can be approved or rejected independently of the overall amendment.
- If an amendment includes both standard and custom items, and only the custom items are rejected, the amendment may still proceed with the standard changes.
- Exception: If the amendment contains only custom items and they are rejected, the entire amendment will be rejected.
Custom amendment item types
If a specific data point is not available in the standard amendment flow, you can use one of the predefined custom item types to request the change.
Use the OTHER custom amendment type for ad-hoc or unique changes that are not covered by the
predefined types.
Example: Custom items with amendment
Amendment general rules and settings
Amendments follow certain global rules and configuration options. These settings define how specific data points behave across different contract types and countries.
Probation period settings
The probation_period data point supports multiple rule types and constraints, depending on the contract type and country-specific settings.
Probation period values are returned with their applicable time unit in the
additional_details.time_unit field of the validation rules response. Time units can vary by
country and employment type and may be DAY, WEEK, or MONTH. Always check the time_unit
field to correctly interpret the min and max values for probation period.
Rule-based configuration
Set the probation period based on a rule and cap value.
Tenure-based configuration
Other configurations define probation periods based on the employee’s expected duration of employment.
Employment terms configuration
- For
INDEFINITEcontracts, the probation period must be between 90 and 180 days, regardless of whether the employment type isFULL_TIMEorPART_TIME. - For
DEFINITEcontracts, the minimum probation period is 20 days. The maximum value is calculated dynamically.
Dynamic calculation for definite contracts
When the contract term is DEFINITE, the API calculates the maximum probation period using contract_duration_in_days and the country-specific rule eor_country_data.max_probation_type_for_definite.
Available rule types:
HALF_OF_CONTRACT_DURATION
Maximum probation period is half the contract duration. Example: A 180-day contract allows up to 90 days.
ONE_QUARTER_OF_CONTRACT_DURATION
Maximum probation period is one-quarter of the contract duration. Example: A 180-day contract allows up to 45 days.
ONE_THIRD_OF_CONTRACT_DURATION (Default)
If no country rule is defined, the fallback is one-third of the contract duration. Example: A 180-day contract allows up to 60 days.
Cap on maximum probation period
The API may apply a cap to limit the maximum probation period, even when it uses a duration-based rule.
- If
additional_detailsincludes a cap value, the system uses the lower value between the calculated maximum and the cap. - The cap applies only when the probation period is based on
HALF_OF_CONTRACT_DURATION,ONE_QUARTER_OF_CONTRACT_DURATION, orONE_THIRD_OF_CONTRACT_DURATION.
Example:
If the contract duration is 180 days and the rule is HALF_OF_CONTRACT_DURATION, the calculated maximum is 90 days. However, if a cap of 60 days exists in additional_details, the maximum probation period is limited to 60 days.
probation_period settings for DEFINITE contracts only support the rule-based configurations
listed above.
Notice period settings
The notice period defines how far in advance either party must give notice to end the contract. Different rules apply depending on probation and contract configuration.
Notice period values are returned with their applicable time unit in the
additional_details.time_unit field of the validation rules response. Time units can vary by
country but are typically WEEK. Always check the time_unit field to correctly interpret the
min and max values for notice period.
Notice period general rules
These rules apply only when notice_period_type is set to CUSTOM.
- The
minandmaxnotice period values range from 0 to 12 weeks. - Rules vary for
FULL_TIMEandPART_TIMEemployees. - The notice period before probation must always be shorter than the notice period after probation.
Tenure-based notice period
Only notice_period_after_probation supports tenure-based rules. These rules depend on the contract duration and define different notice period values for different tenure ranges.
Example rule definition

FAQ
Can I update multiple data points in a single amendment?
Yes. You can include multiple data points in a single amendment request. All changes will be processed together and follow the same approval flow.
What happens if I update an amendment after fetching effective date limits?
You must fetch the effective date limits again after making changes to the amendment. The valid date range may change based on the updated data points.
Can I cancel an amendment after the employee has signed it?
No. Once the employee signs the amendment, it cannot be canceled. You can only cancel amendments before they reach the signature stage.
How do I know which validation approach to use?
For most use cases, the hybrid approach works best. Use client-side validation for fields with
external_validation: false and server-side validation for fields with external_validation: true. This provides immediate feedback for simple fields while ensuring complete validation
for complex fields.
What happens if I include custom items in my amendment?
Custom items are reviewed separately by Deel’s internal team. If only custom items are rejected, the amendment may still proceed with standard changes. However, if the amendment contains only custom items and they are rejected, the entire amendment will be rejected.
Do all amendments require an effective date?
No. The effective date is optional. If you do not provide one, the system automatically sets it to when all parties confirm the amendment. However, some amendments may require an effective date based on the data points being changed.
