Limitations and considerations

Consider the following limitations when working with WhatsApp Flows:

  • Flow name uniqueness — Flow names must be unique within a WABA.

  • Flow JSON size — The maximum size of a Flow JSON definition is 10 MB.

  • Flow JSON version — Supported versions for publishing are 5.1, 6.0–6.3, and 7.0–7.3. We recommend version 7.3.

  • Only DRAFT Flows can be deleted — Published or deprecated Flows cannot be deleted.

  • Data exchange endpoints — Flows with endpoints that exchange data between screens and a business server (the endpoint_uri and data_exchange capabilities) are planned for an upcoming release. Only Flows without an endpoint are currently supported.

  • Flow migration — Copying or migrating Flows between WABAs is not supported. You can clone a Flow within the same WABA using the cloneFlowId parameter.

  • Rate limits — Standard Meta API rate limits apply to all Flow operations.
