Data Change Request API

Data change request is a collection of suggested changes for one or several objects.

Users without privileges to update objects, such as customer sales representatives, or users who want changes reviewed before being applied, can suggest changes. These suggested changes accumulate in the data change requests queue for review and approval by users with approval privileges.

Data changes may include any of the following activities:

Add/update/delete an attribute value
Create an entity or relationship
Delete a relationship
Change object fields like tags, roles, startDate, endDate, and so on.

DCR Security

Not all users can create, review, apply or reject data change requests. To be able to create a data change request, users must have:

READ privilege for objects for which data change request will be created;
INITIATE_CHANGE_REQUEST privilege for the whole object or at least for its attributes for which change requests will be created.

All users can view their own data change requests, but in order to be able to view data change requests from other users, users must have ACCEPT_CHANGE_REQUEST privilege for all objects in data change requests.

For applying or rejecting a data change request, users must have ACCEPT_CHANGE_REQUEST privilege for all objects in the data change request.

Note: Users with ROLE_ADMIN or ROLE_ADMIN_TENANT_* don't need ACCEPT_CHANGE_REQUEST and/or INITIATE_CHANGE_REQUEST privileges. Such users have full control over DCRs.

In order to apply a change request the users must also have READ, CREATE, UPDATE, DELETE, and MERGE privileges on the changed objects and depending on the change type, or, if the applyDcrWithoutPermissions flag is set to true, just a READ privilege. For more details, see topic Permissions.
