Hello guys, I am currently working on integrating VAPI with Zapier to automate calls to customers based on data from Google Sheets. However, I am encountering issues when trying to make POST requests through Zapier's Webhooks. Specifically, I am receiving the following error message: Error Message: Couldn't Get Assistant. Need Either assistant, assistantId, squad, Or squadId. (HTTP Status Code: 400) Here’s a brief overview of my current setup: I am including both the assistantId and the full assistant object in the request payload, as required by the API documentation. The Authorization header uses the correct Bearer token. The JSON data is formatted correctly, but it seems like the request is not recognizing the assistantId or related fields. Could you kindly assist me in understanding what might be causing this issue? Is there a specific format for assistantId or additional details required for the assistant or squad that I'm missing? I would appreciate any guidance you can provide on how to resolve this problem. Below is a snippet of the JSON payload I am currently using: { "assistantId": "aba779ad-8f94-4e78-be1d-c16d15449c5e", "assistant": { "transcriber": { "provider": "deepgram", "model": "nova-2", "keywords": [] }, "name": "Peter", "model": { "provider": "openai", "model": "gpt-4", "systemPrompt": "..." }, "voice": { "provider": "11labs", "voiceId": "nI2Qrkdp8gkUCYPK9fTv" }, "firstMessage": "Zdravím, som Peter...", "endCallMessage": "Dovidenia." }, "customer": { "number": "+421902698385", "name": "Martin" }, "phoneNumberId": "383abe82-9bc0-4a8c-abd2-9b5240a6f4bc", "phoneNumber": { "twilioPhoneNumber": "+1 (650) 667 8638", "twilioAccountSid": "ACb93a304bfa81xxxxxedcd57bdf44c2", "twilioAuthToken": "7f4711b8fb35770677904xxxxxxdb5" } } Than you very much 🙂 https://cdn.discordapp.com/attachments/1282061624508809296/1282061624798347426/Snimka_obrazovky_2024-09-07_o_21.29.27.png?ex=66ddfc6e&is=66dcaaee&hm=4b283a0fe73c921611e18f855f1bcade2bd465491fbc3fb9befb7224c0830579& https://cdn.discordapp.com/attachments/1282061624508809296/1282061625171644598/Snimka_obrazovky_2024-09-07_o_21.31.49.png?ex=66ddfc6e&is=66dcaaee&hm=4a16e100b115d51e21ce6f3b546ae22e856afd02483f2ba6c45539e8f065ea59&

@Fanfantulipan Hello! I'm glad to assist you with integrating VAPI with Zapier. Based on the error message you're receiving, it seems like there might be an issue with how the

assistantId

or the

assistant

object is being recognized by the VAPI when you make the POST request. Here are a few things you can check and try to resolve the issue: 1. **Double-check the Payload**: Ensure that the

assistantId

is correctly placed at the top level of your JSON payload and that it matches the format expected by the VAPI. 2. **Verify Assistant Object**: Confirm that the

assistant

object is complete and correctly formatted according to the VAPI documentation. All required fields should be present. 3. **Headers and Authorization**: Make sure that the Authorization header is correctly formatted with the Bearer token and that there are no issues with token expiration or permissions. 4. **Content-Type Header**: Ensure that the

Content-Type

header is set to

application/json

in your POST request. 5. **Check for Typos**: Simple typos or case sensitivity issues in the field names can cause the API to not recognize the parameters. Verify that all field names are correct. 6. **API Endpoint**: Confirm that you are posting to the correct API endpoint and that the endpoint is expecting the payload structure you are sending. 7. **Zapier Configuration**: Review your Zapier webhook configuration to ensure that it's set up to send the data in the correct format and that there are no additional transformations or formatting that might be altering the payload. If after checking these points the issue persists, it might be helpful to see the exact request being sent to the VAPI. You can use tools like Postman or cURL to replicate the request outside of Zapier to see if the issue is with the VAPI or with how Zapier is sending the request. If you need further assistance or if there's anything else I can help you with, please let me know!

Additionally, I have successfully tested making calls directly through the VAPI interface, and everything works as expected. However, when attempting to do the same via Zapier, the above error occurs.

@Fanfantulipan Sweet. Have a great day!
