Previously, the HTTP Request action in Workflows did not support the content type application/json-patch+json, which is needed by PATCH operations in the IdentityNow APIs. This meant that users of the HTTP Request action could not invoke PATCH APIs in IdentityNow, like update role.
With the latest update to Workflows, the HTTP Request action now supports the JSON PATCH content type. When invoking a PATCH API in IdentityNow, please use the following request content type in the HTTP Request action.
Only use the JSON Patch request content type when invoking an IdentityNow PATCH API. For any other operation, like POST or PUT, please use the JSON content type.
