Purpose

To perform a composite API call, consisting of one or up to five sub-requests.

Endpoints

Request Details

Request URL

{api-domain}/crm/{version}/__composite_requests

Header

Authorization: Zoho-oauthtoken d92d4xxxxxxxxxxxxx15f52

Scope

ZohoCRM.composite_requests.CUSTOM
(and) Scope of the subrequest

Sample Request

Copiedcurl "https://www.zohoapis.com/crm/v6/__composite_requests"
-X POST
-H "Authorization: Zoho-oauthtoken 1000.03xxxxxxxxxxxxxxxxxa5317.dxxxxxxxxxxxxxxxxxfa"
-d "@newdata.json"

Request JSON

rollback_on_failboolean, optional
Represents whether to rollback the composite API request if any of the sub-requests fail. The default value is false.
parallel_executionboolean, optional
Represents whether to process all independent sub-requests (sub-requests with no dependencies/references) in parallel. The default value is true. If "rollback_on_fail" is true, then the default value of this key is false.
__composite_requestsJSON array, mandatory
The JSON array containing the details of the sub-requests.
- sub_request_id (string, optional) - The request ID for the corresponding sub-request. The accepted regex is [a-zA-Z0-9][a-zA-Z0-9_]*.
- uri (string, mandatory) - The request URL of the corresponding sub-request. The accepted regex is /crm(/.*)?/v[0-9]+([.][0-9]+)?/.*.
- method (string, mandatory) - The request method of the corresponding sub-request. The possible methods are GET, POST, PUT, PATCH, and DELETE.
- params (JSON Object, optional) - The parameters for the corresponding sub-request.
- body (JSON object, optional) - The request body of the corresponding sub-request.
- headers (JSON object, optional) - Headers for the corresponding sub-request. Note that you cannot use the headers "authorization" or "x-crm-org" in this key.

Note

rollback_on_fail and parallel_execution keys cannot both be true, simultaneously. For such a request, the system throws the AMBIGUITY_DURING_PROCESSING error.
All Delete APIs (except Notification APIs) are only supported with ID support in the URL. Bulk delete option is not supported.
When rollback_on_fail is false:
- Workflows, approvals, and other automation actions are triggered as intended.
- One API credit is consumed.
When rollback_on_fail is true:
- Workflows:
  - The automation actions are executed only when all the sub-requests are served and a rollback is not performed. If one or more sub-requests fail and a rollback happens, the automation actions are not triggered.
  - For example, consider the case where a workflow is triggered every time a lead is created with the company name starting with 'S'. In sub-request 1, a lead is created, whose Company name starts with 'S', and sub-request 2 edits the newly created record's company name so that it does not start with 'S'. Only after executing both the sub-requests the workflow will be executed. But in this case, the workflow will not be triggered because the newly created Lead's company name is already updated in sub-request 2, and the criterion for the workflow is not met. Consider another case, where in sub-request 1, a lead is created, whose Company name is 'Silicon Solutions', and sub-request 2 edits this newly created record's website. If none of the other sub-requests change the company name of this newly created record, after executing all the sub-requests successfully, the workflow will be triggered.
- When a rollback happens, one credit will be used for the composite API.
- When all the sub-requests are successful, two credits will be used for the composite API.
Each composite API consumes five concurrency credits, irrespective of the number of sub-requests.
Each composite API reduces the sub-concurrency by one, while the sub-requests consume their respective sub-concurrencies.

Possible Errors For the sub-requests

MANDATORY_NOT_FOUND
You have not specified the mandatory key in one of the sub-requests, the data type is not consistent with the field, or not compliant with the regex.
Resolution: Input all manadatory values for every sub-request following the regex. Make sure the data type of the input matches with the field's.
INVALID_DATA
You have specified an invalid sub_request_id
Resolution: Specify a valid sub_request_id. The accepted regex is [a-zA-Z0-9][a-zA-Z0-9_]*.
INVALID_DATA
You have specify an invalid value for one of the keys
Resolution: Specify valid values for all the keys. Refer to the sample input section for more details.
DUPLICATE_DATA
You have specified the same sub_request_id for more than one sub_request
Resolution: Specify unique sub_request_id for all sub-requests.
NOT_ALLOWED
You have specified a version higher than that of the composite API's for one or more sub-requests in their URLs
Resolution: Specify a version equal to or less than that of the composite API for all the sub-requests.
NOT_SUPPORTED
You have tried to invoke an API that is not supported by composite API
Resolution: Refer to the supported APIs section above for the list of allowed APIs in a composite request.
LIMIT_EXCEEDED
You have exceeded the limit in the sub-request
Resolution: There are restrictions on the number of records that you can create, update, or delete in a composite request. Refer to the "Allowed APIs" section for the limits applicable to each API.
INVALID_REFERENCE
You have given an improper reference in the request body
Resolution: Refer to the notes section and sample input section for details on how to give a proper reference.
INVALID_REFERENCE
The response used in the given reference does not have a proper value
Resolution: Specify a valid reference.
INVALID_REFERENCE
You have given a reference which is yet to be executed
Resolution: This error is thrown for sequential execution ("parallel_execution" is false). Arrange the sub-requests so that the reference can be given properly.
INVALID_REFERENCE
The given reference refers to the same sub-request as it is referred to in
Resolution: Give a reference from another sub-request.
INVALID_REFERENCE
The sub-request referred to in the reference has failed
Resolution: This error is thrown for parallel execution ("parallel_execution" is true). You can only use successful sub-requests as references.
LOOPING_FOUND
The sub-requests are referring to each other
Resolution: This error is thrown for parallel execution ("parallel_execution" is true). Sub-requests cannot have references to each other. Specify the references such that there is no looping.
ROLLBACK_PERFORMED
The sub-request was rolled back because another sub-request in the composite API has failed
Resolution: This error is thrown only when "rollback_on_fail" is true. Make the necessary corrections so that the failed API can be successful.
PROCESSING_STOPPED
The sub-request was rolled back because another sub-request in the composite API has failed
Resolution: This error is thrown only when "rollback_on_fail" is true and there were unexecuted sub-requests when the transaction was rolled back. Make the necessary corrections so that the failed API can be successful.
REQUEST_TIMEOUT
The execution time taken to complete all the sub-requests in parallel has exceeded the default timeout period of five minutes
Resolution: Check the network for connectivity issues, or other reasons for execution time exceeding five minutes. The already triggered sub-request may be successfully executed in the back-end, even if this error is populated.
REQUEST_TIMEOUT
This error is thrown when connection time-out occurs during NIO flow and CRM is yet to receive the request
Resolution: This error is thrown for parallel execution ("parallel_execution" is true). Check the network for connectivity issues.
INTERNAL_ERROR
Internal server error
Resolution: Contact your system administrator or the support team.

Status Codes for a Composite Request

The following are the status codes in the response of a composite request.

When "rollback_on_fail" is true:
- Status code is 400, when a rollback is performed (one or all the sub-requests failed).
- Status code is 200, when a rollback is not performed.
When "rollback_on_fail" is false:
- Status code is 400, when none of the sub-requests is triggered.
- Status code is 207, when a few of the sub-requests are triggered.
- Status code is 200, when all the sub-requests are triggered. Note that a composite request is considered a success when all the sub-requests are triggered, irrespective of the success or failure of each of these sub-requests.
