HI @sacom01,

You're getting a 403 HTTP status error which means that the client understands the request but it did not authorize it. There's a permissions/authorization issue when connecting to the server.

I would reach out to your admin for ms teams at your company. I'm assuming you are using some kind fo API key to connect, you may need to check or configure the settings/credentials.

Let me know what you find out.

Hi,

Good to hear that's working now!

We'll go ahead and close this out, but feel free to open another if you have any new questions.
