How to Pass Dynamic URL Parameters in Vapi.ai Work...
# supporte

05/14/2025, 2:41 PMHi everyone 👋,
I’m working on a Vapi.ai workflow and need to send dynamic URL parameters in an API Request node. I understand that I can use double curly braces for dynamic variables, like {{userId}}, but I’m unsure how to set these variables dynamically during the call.
Specifically, I’m looking to:
• Pass dynamic values (e.g., userId, status) into the API Request node’s URL.
• Ensure these values are set correctly during the call initiation.
I’ve read the Vapi documentation on dynamic variables, but I’m still a bit confused about the implementation.
Could someone guide me on how to achieve this? Any examples or best practices would be greatly appreciated!
Thanks in advance! 🙏

05/14/2025, 2:43 PMTo pass dynamic URL parameters in a Vapi.ai Workflow API Request node, set your variables (e.g., userId, status) during call initiation by including them in the assistantOverrides.variableValues object. For example:
Copy code
json
{
"assistantId": "your-assistant-id",
"assistantOverrides": {
"variableValues": {
"userId": "12345",
"status": "active"
}
},
"customer": {
"number": "+1xxxxxxxxxx"
},
"phoneNumberId": "your-phone-id"
}"param1": "{{userId}}"k
