HI team,

I am using a citrix application to connect to calendly with my users, I had a problem to verify the schedule a meet and the .har file is giving me this error: 

 

"method": "POST",          "url": "https://calendly.com/api/booking/invitees",

 

"response": {          "status": 400,

 

 "text": "{\"failure\":{\"error\":\"Oops, something went wrong.\",\"code\":\"forbidden\",\"context\":{\"telemetry_id\":\"tid-3f6fcd30-751f-4f1a-8468-25ece116e58f\",\"explanation\":\"Your meeting request could not be finalized with this host. If you feel you've reached this message in error, please reach out to support with below error code.\",\"stytch_block_verdict\":true}}}"          },

 

Is this because in Calendly platform is blocking me with the IP address we are using? 

 

It works outside the citrix, should we ask for a whitelist in Calendly side, how ca we do that?

Hey ​@Johan73735 - 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.

Since it works outside of Citrix, that environment may be contributing to the block, but the decision can be based on multiple signals rather than IP alone.

Finally, Calendly does not offer a general IP allowlisting process for booking traffic at this time. However, if you’re able to contact Calendly Support here and share the telemetry ID from the error along with details about your Citrix environment, our team can review that block more closely for you and advise on possible next steps.

Thanks!
