Connecting Zapier Webhook To VAPI
Hi Aryan ®,
If you need help setting up or troubleshooting your Vapi webhook integration, here are some key steps and considerations:
1. Set Up Local Webhook Forwarding:
- Use the
vapi listen command for local testing (vapi listen --forward-to localhost:3000/webhook).
- Employ a tunneling solution like ngrok to expose your local server (ngrok http 4242).
2. Update Your Webhook URLs:
- Once the public URL is obtained from ngrok, update your Vapi Dashboard with this URL for webhook configurations.
3. Test Webhook Events:
- Trigger events in your Vapi environment to ensure they're being received and forwarded correctly to your local setup.
4. Troubleshooting:
- Ensure your local server is running.
- Verify the correct port and endpoint path in your configurations.
- Use tools like curl to test your endpoint directly if needed.
You can follow this guide for detailed instructions on setting up local webhook testing.5 replies

Parameters derived from properties in APIRequest tool not working correctly
Hi Ovi1kanobe,
If you are encountering issues with API request tools, particularly with query parameters not being passed correctly, ensure that your request configuration includes all required fields such as
type, method, url, and other relevant data according to the API Reference.
If the type is apiRequest, the object should include method, url, and credentialId along with any necessary headers and body. Check if the rejectionPlan and variableExtractionPlan are properly defined to manage any issues arising during the request execution.
Also, keep in mind the CreateApiRequestToolDto configuration, and ensure that all required fields are correctly set up, which may impact how the parameters are recognized and executed during tests or actual requests.
For detailed steps, you can reference the SDK documentation to ensure your implementation follows the required specifications.6 replies

Transfer Call not working
Hi Gigamajig Inc.,
To troubleshoot transfer call issues effectively, consider the following steps:
1. Verify the Vapi Forwarding:
- Use the Vapi API to confirm if the transfer was initiated successfully. You can execute a GET request using cURL or the SDK, as shown in the documentation here.
2. Check Configuration:
- Ensure that the
serverMessages in the assistant settings do not include "phone-call-control" if Vapi is managing the call control. Use phoneCallProviderBypassEnabled: false for standard Vapi forwarding.
3. Review Call Transfer Scenarios:
- Ensure the use case is supported. For example, web-to-phone number transfers aren't supported.
4. Analyze Telephony Provider Logs:
- Obtain the phoneCallProviderId from the Vapi API call response. Check logs on your telephony provider (Twilio, Vonage, Telnyx) for transfer-related issues.
5. SIP Provider Analysis (if applicable):
- Conduct SIP packet analysis through Wireshark using REFER packets to determine if the transfer request was appropriately sent and acknowledged.
6. Check Destination Number:
- Confirm that the destination number format is correct, includes the country code, and is reachable.
If the problem persists, it may be worth checking your telephony provider’s dashboard for specific errors or configuration settings that might impact call transfers. This could involve examining transfer scenarios or SIP configuration as outlined in the detailed documentation here.
If you need further assistance in resolving this, ensure you have tested each of these areas thoroughly.7 replies
Dynamic Transfer Tool in Squad for Transfer to Agent Issue
Hi Toph,
To implement a dynamic call transfer using Vapi, ensure the following steps are followed:
1. Create a Dynamic Transfer Tool:Leave the
destinations array empty, and specify the tool type as transferCall. Here's a basic structure:
2. Webhook Setup:Use a transfer-destination-request webhook to dynamically determine the transfer destination. Make sure your server logic correctly interprets the context from the webhook and responds with the appropriate destination.
3. Assistant Configuration:Integrate your dynamic transfer tool into an assistant configuration, enabling the transfer-destination-request server event to activate dynamic routing.
4. Testing:Assign the created assistant with the dynamic transfer tool to a phone number. Test various transfer scenarios and monitor the webhook server logs to verify the routing decisions are being made correctly.
For complete procedural steps, you can refer to the Dynamic Transfers documentation.4 replies

SSML parsing working inconsistently - delivering a system for a client asap
Hi Logos,
For SSML parsing issues, ensure that your voice agent is properly configured to support SSML inputs. SSML parsing might not function consistently due to varying factors such as incorrect SSML syntax or voice agent settings.
To troubleshoot, consider the following steps:
1. Check SSML Syntax: Ensure that your SSML is correctly formatted. Each tag should be properly closed and nested according to the SSML specification.
2. Review Voice Agent Settings: Ensure that the voice profile you are using supports SSML. Not all voice profiles have SSML capabilities.
3. Validate Inputs: Confirm that inputs containing SSML are reaching the voice agent without being altered or stripped of tags.
4. Test with Different Providers: If using a non-native provider, verify their SSML support, as some providers may have limited or different SSML capabilities.
For further details, you can refer to the API Reference.
If these do not resolve the issue, consider examining logs for errors related to SSML parsing which may provide more insight into specific problems.

Issue: Assistant not receiving variables (Name, deal_id)
Hi maureen,
To ensure that the dynamic variables are set correctly for your assistant, make sure that your JSON payload specifies the
assistantOverrides with the variableValues accurately. Here's an example structure for setting the variables:
Ensure that:
- The JSON payload is well-formed and includes all necessary sections.
- The call to the /call/phone endpoint includes the correct assistantId and phoneNumberId.
For further details, you can refer to the documentation on using dynamic variables. If the assistant still doesn't receive the variables, double-check if they appear correctly in the Vapi Call Logs under "Variables" section.5 replies
transferCall Tool Executes But Call Ends - No Transfer
Hi Burak,
To troubleshoot issues with call forwarding dropping immediately after initiation, follow these steps:
1. Verify Forwarding Initiation: Check if Vapi successfully initiated the forwarding.
- Use the API to fetch the call details and look for
"endedReason": "assistant-forwarded-call". If not present, verify your configuration.
2. Configuration Check: Ensure your serverMessages does not include "phone-call-control". If present, it's overriding Vapi's control.
3. Telephony Provider Logs: If the call was marked as forwarded but still drops, check your telephony provider's logs using the phoneCallProviderId for errors in their dashboard.
4. SIP Analysis (if applicable): Download the PCAP file and use Wireshark to check for SIP transfer packets. Look for REFER packets and responses.
5. Common Solutions:
- Verify the destination number format is correct and reachable.
- Ensure phoneCallProviderBypassEnabled is set to false unless custom call control is implemented.
For detailed steps, see the Debug call forwarding drops guide.7 replies
