Structured data missing from webhook, after call ...
# support
e
After calling my assistant and completing the conversation, I don't see any structured data in the webhook data. I'm wondering why the structured data isn't appearing in the webhook payload after the call is finished. I've used this feature successfully many times before without any issues, so I'm confused why this problem is occurring now. Has there been any update or change to how structured data is handled in webhooks? Please advise on this issue.

Hi there! 👋 I understand how frustrating it can be when features that were working suddenly stop functioning. I can't pinpoint exactly why your specific implementation is failing without seeing your configuration or logs, but I can definitely help with common causes and troubleshooting steps for this issue. Based on the information I found, there are several potential reasons why structured data might be missing from your webhook payload: ## Recent Updates That Might Be Affecting Your Webhooks There have been some recent updates that could potentially impact webhook structured data handling: - On January 29, 2025, there were [updates to Tool Calls](https://docs.vapi.ai/changelog/2025/1/29) where the
ToolCall
schema was revamped. You should update your tool calls to use the new
function
property with
id
and
function
details (instead of older
tool
and
toolBody
properties). - The same update introduced [Regex Validation with Json Outputs](https://docs.vapi.ai/changelog/2025/1/29), which could be filtering or altering your structured data. - There's a known [casing discrepancy issue](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1341204221826957432) between Vapi webhook logs (which use snake_case) and server logs (which use camelCase). ## Common Issues & Troubleshooting Steps Here are some common issues and troubleshooting steps to check: 1. **Check Webhook Configuration**: - Verify your webhook URL is correctly configured in the Vapi platform - Confirm the events expected to trigger the webhook are actually occurring - Review the HTTP method used (GET, POST, etc.) 2. **Inspect Logs**: - Check server logs for errors preventing the webhook from being called - Look at webhook delivery logs for clues - Use browser developer tools to inspect network activity 3. **Data Format Issues**: - Ensure the data structure matches the expected format - Check that serialization isn't altering the structure
- Confirm the
Content-Type
header is set to
application/json
- Verify JSON formatting is correct (line breaks should be escaped as
\\n
) 4. **Tool Configuration**: - If you're using the
tool-call
block, make sure parameters are correctly defined - Check that dynamic variables are being passed correctly - Verify the
toolCallId
in the response matches the one sent in the request 5. **Recent System Changes**: - The issue could be due to a temporary system glitch - Check if you've made any recent changes to your implementation Would you like me to provide more specific troubleshooting steps for any of these areas? Or do you have any additional details about your implementation that might help narrow down the cause?
