Hi @javiernei,
Welcome to the Community.
Suppose you see the error "Invalid request: method must be POST" when connecting Social Champ to Zapier. In that case, it likely means the app expects a different type of request—typically during authentication. Make sure you're using the correct sign-in method (like an API key or OAuth), try reconnecting in an incognito browser session, and confirm whether you're using a public integration or a custom webhook. If Social Champ isn't officially supported, you may need to use Webhooks by Zapier and structure your request manually.
Feel free to share an obscured (blurred) screenshot to help troubleshoot further.
Hola JammerS, thanks for your reply.
Social Champ is officially supported. I tried in another browser, but the message is the same:
The app returned "Invalid request: method must be POST".
Do not know how to do. Sad sad sad.
