Contact and chat APIs not working since Monday 13 May 2024

curl --location ‘’ --header ‘Content-Type: application/json’ --header ‘Authorization: Bearer api_key’

Expected: list of contacts
Received a single contact with the user itself and other contacts not being fetched despite being displayed/present on zoom app.
body{“message”:“hi”, “to_contact”:“emailid”}
Returns user blocked error despite that not being the case
“code”:5421,“message”:“Can not send message to a blocked contact.”

Hello Team,
Could you please help me resolve this issue?
I am still unable to use any of the APIs.

We have started encountering this issue over the weekend as well (May 19).

error 5421

Sending to a channel is still working, just to specific users
