Good afternoon, I have an issue regarding calling a function in Vapi, that should be transferring appointment details to a make.com webhook. While the make.com webhook is listening to determine the data structure, while doing the call, and after the call, I assume the function is not being called as the webhook in make.com is still listening. What are possible problems, I already went through many options. I hope you can help me. Kind regards, Steve Biewer

Hey again, Here are some pictures of - The make.com scenario - The function -The prompt Note: I unfortunately cannot show you the server URL. They are the same though.

@steveboy01 Thank you for the update, Steve. Since I'm unable to view pictures, let's proceed with a few troubleshooting steps that you can follow: 1. **Verify the Webhook URL**: Even though you've mentioned the URLs are the same, please ensure that there are no typos or accidental spaces in the webhook URL you've configured in VAPI. 2. **Check the Function Configuration**: Review the function configuration in VAPI to ensure that it's set up correctly to send data to the make.com webhook. This includes the HTTP method (POST, GET, etc.), headers, and any required authentication. 3. **Test the Webhook Manually**: Try to trigger the make.com webhook manually using a tool like Postman or cURL. This can help you verify that the webhook is operational and can receive data as expected. 4. **Review Logs**: Check the logs in VAPI and make.com for any error messages or indications of what might be going wrong. This can provide clues about connectivity issues or data format problems. 5. **Simplify the Scenario**: If possible, simplify the make.com scenario to the bare minimum to test the connectivity and gradually add complexity once the basic connection is confirmed. 6. **Contact Support**: If you've gone through all the above steps and the issue persists, it might be best to contact VAPI support directly with details of the function call and any error logs you have. They might be able to provide more specific guidance based on their system's behavior. If you have any specific error messages or details about the function call that you can share, please do so, as it might help in diagnosing the issue further. If you need assistance with contacting support or any other action, please let me know!

Could you evaluate this prompt? Identity You are a VAPI Scheduling Assistant, responsible for managing appointments using the schedule function and sending details to Make.com webhooks while troubleshooting integration issues. Style Maintain a professional, concise, and helpful tone. Provide clear, step-by-step instructions and troubleshooting guidance. Response Guidelines Use bullet points for clarity. Include JSON examples when relevant. Limit troubleshooting to 3–5 key checks per issue. Task & Goals Schedule an appointment by collecting: Attendee name, date & time, notes (if any) Send details to Make.com, ensuring: Correct webhook URL & data format Necessary headers/authentication Verify & troubleshoot issues: Check URL, connectivity, data format, authentication, and logs Example Execution json Copy Edit { "attendee": "John Doe", "date": "2025-02-10", "time": "15:00", "notes": "" } Sent to https://hook.make.com/your-webhook-url ✅ Success | ❌ Failure – Troubleshooting steps provided

@steveboy01 The prompt you've provided outlines a clear and structured approach for a VAPI Scheduling Assistant's responsibilities. Here's an evaluation based on the criteria given: - **Identity**: The identity is well-defined, focusing on scheduling and integration with Make.com webhooks. - **Style**: The style directive to maintain a professional, concise, and helpful tone is appropriate for the intended support and troubleshooting role. - **Response Guidelines**: The use of bullet points and JSON examples will enhance readability and comprehension, which is beneficial for users following the instructions. - **Task & Goals**: The tasks are clearly outlined, with specific goals for collecting appointment details and ensuring successful integration with Make.com. - **Troubleshooting**: Limiting troubleshooting to 3–5 key checks is a practical approach to avoid overwhelming the user and to focus on the most common issues. - **Example Execution**: The JSON example provided is relevant and gives a clear template of what data needs to be collected and sent. Overall, the prompt is well-constructed and aligns with the objectives of a VAPI Scheduling Assistant. It sets clear expectations for the assistant's role and provides a framework for assisting users effectively. The inclusion of an example execution with a JSON payload and a webhook URL is particularly helpful, as it gives users a concrete example to follow. The success and failure indicators, along with troubleshooting steps, will guide users through resolving issues they may encounter.

Should this prompt be calling the function properly

@steveboy01 To determine if the prompt is correctly calling the function, I would need to see the specific code or command being used to call the function within VAPI. The prompt you've provided is a guideline for how to structure the interaction, but it doesn't contain the actual function call or the technical details needed to execute it. For a function to be called properly in VAPI, you would typically need: - The function name and any required endpoint. - The necessary parameters, such as attendee name, date, time, and notes. - The correct headers and authentication tokens if required by the webhook. - The appropriate method for the HTTP request (usually POST for webhooks). If you have a code snippet or command that you're using to call the function, please share it (without sensitive information like URLs or tokens), and I can help you evaluate whether it's set up correctly. If you're unsure how to format the function call, I can guide you through the process.

what do you mean with any required endpoint

@steveboy01 Apologies for any confusion. In the context of APIs and webhooks, an "endpoint" refers to a specific URL or URI (Uniform Resource Identifier) where an API can be accessed by a client application. When you call a function that interacts with an external service, like a make.com webhook, you typically need to specify the endpoint to which the data should be sent. Here's a breakdown of what an endpoint usually includes: - **Base URL**: The root address of the API service (e.g.,

https://api.make.com

). - **Path**: The specific path to the resource or function you want to access (e.g.,

/webhooks/receive_data

). - **Query Parameters**: Optional key-value pairs that can be appended to the endpoint to provide additional information (e.g.,

?user_id=123

). When combined, these form the complete endpoint that you would call to interact with the API or webhook:

https://api.make.com/webhooks/receive_data?user_id=123

In the case of your function call to send appointment details to a make.com webhook, you would need to specify the endpoint provided by make.com where the VAPI should send the data. This endpoint is unique to your make.com scenario and is used to ensure that the data reaches the correct destination. If you're setting up a function call in VAPI, you would include this endpoint in your configuration, along with any other necessary parameters, headers, and authentication details required by the make.com webhook to successfully receive and process the data.

@steveboy01 can you share the call ID so I can take a look?
