Before you test any booking, contact, or scheduling flow in Retell, make sure your Retell agent is using the correct Sympana Connector function setup and webhook configuration.Start by connecting Sympana Connector to Retell using the Retell setup guide. Then open the Retell function tools page in this documentation and use the exact Sympana Connector function names shown there. These names need to match the expected Retell setup so your agent can call the right actions.After the functions are added, review your prompt. The prompt should clearly tell the agent when to get contact data, when to create or update a contact, when to retrieve available slots, and when to create or reschedule an appointment. Without this instruction layer, the functions may exist but the agent may not use them correctly.Next, test the workflow with a real use case. Confirm that the agent can identify the contact, retrieve available slots, and complete the intended action inside GoHighLevel. If a function does not fire correctly, check the function name, the prompt instructions, and the related Sympana webhook setup.If you still run into issues, contact support at support@sympana.com.
