Can’t send IM chat message using API

(Business Account)
When I’m trying to send IM message to user using API I got next response:
400 Bad Request {‘code’: 2, ‘message’: ‘Send IM Message failed, please try later again.’}
What does ‘code: 2’ mean? I can’t find any reference to this in documentation.

Same app code is well working with free account.

Thank you!

Hi @igor.pischik,

Hi @igor.pischik,

Can you send us your account ID and email to developersupport@zoom.us?

Hi @igor.pischik,

Wanted to follow up, right now there is a bug within our API that is preventing sending messages for some users. We are currently working on this and should have a fix tentatively for our June release.

Thanks
