When the "Manage Pipelines" page under CRM Settings shows no pipeline configured, the Zoho CRM API returns a 204 No Content response for pipeline-related endpoints on the Deals module. However, once a custom pipeline is added, the API correctly returns data for both the Standard pipeline and the newly created custom pipeline.
This means the Standard/default pipeline is invisible to the API unless at least one additional custom pipeline exists — which is unexpected behavior.
The API should return the Standard (default) pipeline even when no custom pipelines have been created. A 204 response implies no content exists, but the Standard pipeline is always present by default and should be reflected in the API response.
This behavior breaks third-party integrations that rely on the pipeline API to read Deals data. In cases where an end user has not manually added a custom pipeline, the integration receives no pipeline data and cannot function correctly — even though the Deals module itself is active and in use.
We have reproduced this behavior across multiple CRM instances, confirming it is consistent and not isolated to a single account configuration.
Please let us know if you need API logs, specific integration IDs, or any further details to investigate.
