Parameters issue

Hi there! I see you're having trouble with parameters not appearing when connecting with make.com. Based on the images you shared, I can see the arguments section is showing as "Empty" when it should be displaying parameters. Here are some common reasons this might be happening and how to fix it: 1. Webhook Configuration Issues - Double-check your webhook URL in make.com is correctly configured and matches exactly with what Vapi expects - Ensure there are no typos or extra spaces in the URL 2. Data Formatting Problems - Make sure your data is correctly formatted for make.com expectations - Check that JSON serialization is properly configured with correct Content-Type headers 3. Variable Definition and Reference - Ensure variables are properly defined in the parent block - Reference variables correctly in tool calls using proper syntax, for example:
Copy code
json
   {
     "body": {
       "message": {
         "toolCalls": [
           {
             "function": {
               "name": "send_to_endpoint",
               "arguments": {
                 "parameter_name": "{{variable_reference}}"
               }
             }
           }
         ]
       }
     }
   }
4. Browser-Related Issues - Try clearing your browser cache or using a different browser - Disable any extensions that might interfere with make.com 5. Function Structure - Verify your function is properly structured with all required fields:
Copy code
json
   {
       "type": "function",
       "function": {
           "name": "function_name",
           "parameters": {
               "type": "object",
               "properties": {
                   "param_name": {"type": "string"}
               }
           },
           "description": "Description of what the function does"
       },
       "async": false,
       "server": {
           "url": "https://your-server-url/path"
       }
   }
For troubleshooting, I recommend:
- Testing with minimal datasets to isolate the issue - Using tools like Postman to manually test your API endpoints - Implementing detailed logging to track where data flow might be disrupted - Checking both Vapi and make.com logs for any error messages Let me know if any of these suggestions help or if you need more specific guidance! 🙂 Sources: - [Discord Channel Message](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1336399188665040968) - [Discord Channel Message](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1335308574556946480) - [Discord Channel Message](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1315677399026765855) - [Discord Channel Message](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1333880245681393756)
