If you're encountering WhatsApp API error 2064, which states "Invalid Flow ID," it means the specified Flow ID is either incorrect, doesn’t exist, or isn’t associated with your WhatsApp Business Account (WABA). This error can prevent your automation flows from executing properly.

Possible Causes of Error 2064

  1. Incorrect Flow ID – The Flow ID used in your request may be mistyped or invalid.

  2. Flow Not Linked to Your WABA – The specified Flow ID belongs to a different WhatsApp Business Account.

  3. Deleted or Inactive Flow – The flow may have been deleted or is in an inactive state.

  4. API Permission Issues – Your account may lack the necessary permissions to access the flow.

How to Fix WhatsApp API Error 2064

1. Verify the Flow ID

Double-check the Flow ID in your API request. Retrieve the correct Flow ID from the WhatsApp Business Manager or API response.

2. Ensure the Flow Belongs to Your WABA

Confirm that the Flow ID is created under the same WABA used in your API request. If managing multiple WABAs, ensure you're using the correct account.

3. Check the Flow’s Status

Make sure the flow is not deleted or inactive. If it was recently modified, refresh the API request with the latest Flow ID.

4. Verify API Permissions

Ensure that your API credentials have the necessary permissions to access flows. If needed, update your access settings in Meta’s Developer Console.

5. Contact Meta Support

If you've verified everything and the issue persists, reach out to Meta’s Business Support for assistance.
