test_mode: true on the request envelope to validate the envelope and every event without creating a canonical record or forwarding to OpenAI. Use this as the final integration check before sending live conversions.
Results
Inspect every result in a200 response. Possible statuses are accepted, duplicate, suppressed, invalid, and, in test mode, validated. Retry the complete request with the same event IDs only after a 503, when Thrad could not determine a durable outcome.
Common errors
