"stytch_block_verdict:true"

Hey ​@Johan41001 - Thanks for reaching out!

In this case, stytch_block_verdict: true means the booking request was blocked by Calendly’s security checks during the scheduling flow.

In other words, the request reached Calendly successfully, but it was prevented from being finalized because it was flagged as suspicious. It does not usually point to a formatting issue with the API request itself.

If you’re seeing this unexpectedly, the best next step is to contact Calendly Support here and include the telemetry/error ID from the response so the team can review the specific block for you.
