Anyone been able to successfully connect to Xero API through an action in CustomGPT?
I’ve been able to get through the authentication flow okay and get Xero’s pop up window inviting me to authorize access. But when I then prompt the GPT, it buffers on Starting action and doesn’t go anywhere.
Thinking the connection may need the tenant ID in the header, in which case it isn’t possible as OpenAI doesn’t allow custom headers in CustomGPT actions yet.
So frustrating, if that’s what it is as it prevents connection of a lot of apps.
