3773045 - Error when clearing extension fields using empty string: "Data format for ABC is invalid. Use code"

• You get an error when trying to clear an extension field using API Patch calls
• Return validation error: “Data format for ABC is invalid. Use CODE”. (ABC is an extension field of format CODE)
• Issue can occur with extension fields of other Type and Format as well

SAP Sales Cloud and SAP Service Cloud Version 2

1. Select any entity (example: Account).
2. Perform a PATCH request to the account service endpoint: https://{tenantURL}/sap/c4c/api/v1/account-service/accounts/{UUID}.
3. Use a body that sends an empty string for the extension field to be cleared, for example:
   { "id": "the id", "displayId": "the id", "extensions": { "ABC": "" } }
4. Observe the error: “Data format for ABC is invalid. Use CODE”.

• Empty string "" is not a valid value for extension fields.
• SAP Sales and Service Cloud V2 requires that extension fields be explicitly set to null (not an empty string "") when you want to clear them.
• Passing "" for fields triggers a format validation error and is as expected

1. To clear an extension field, include it in the payload and set its value to null.
2. Example PATCH body:
   { "id": "the id", "displayId": "the id", "extensions": { "ABC": null } }
