BYOC Edge Webhook Payload Truncation on Large IVR Data

Voice & Telephony

Stuck on a silent failure where the BYOC Edge drops outbound webhook payloads exceeding 2KB when triggered by a complex IVR flow. The ServiceNow integration receives a 200 OK but the JSON body is truncated, causing the Data Action to fail validation on the missing history array. Is there a documented payload size limit for BYOC Edge webhook invocations that requires chunking?

This looks like a configuration mismatch rather than a hard platform limit.

  • Verify the maxPayloadSize in the BYOC Edge configuration is set above 2KB.
  • Check if the IVR data action is inadvertently splitting the JSON array.
  • Ensure the ServiceNow endpoint accepts multipart/form-data if binary data is included.
