Question

Lemon Squeezy OAuth connection returns 400 Bad Request

I am trying to connect my Lemon Squeezy store to Zapier.

The connection process works normally until the authorization step:

Zapier → Lemon Squeezy → Connect → Authorization Request → Authorize

After I click “Authorize”, Lemon Squeezy immediately returns:

“Oops! An Error Occurred. The server returned a 400 Bad Request.”

I have already tried:

The same 400 Bad Request occurs every time.

Could you please check whether there is an OAuth authorization issue with my Lemon Squeezy account/store or the Zapier integration?

Thank you.
