I am a developer at Switchboard Health. I am working on a major project using VAPI and I have run into an issue with the webhooks. Our architecture uses AWS Lambda functions and I am trying to get a VAPI assistant to connect to my webhook. When it tries it is getting a 403. This appears to be due to the size of the json payload being sent. It’s 40+ KB in size. I think AWS may limit the allowable body to be under 40KB. Most of what is in the end-of-call-report is stuff that I don’t need in my webhook. I really only need the “call” and “message” sections. Is there any way that I can configure VAPI so that it only sends me what I need?

Problem solved, there was a firewall rule that was limiting the size of a POST payload.
