Nginx

I was building a billing automation for a managed Chatwoot platform for one of my clients. The plan was simple: daily cron, read the inbox list from Chatwoot, turn it into Moneybird invoices. The API docs were clear. The access token was fresh. And every single call came back with:

{"errors":["You need to sign in or sign up before continuing."]}

HTTP 401. Every endpoint. Every variation of the auth header I tried. User access token, platform token, query parameter, Bearer prefix, no prefix. Same answer.
