Project Title Debug Production Clover POS OAuth – Invalid OAuth Credentials (Base44 App) Project Description I’m looking for an experienced Clover POS developer to help debug and resolve a production OAuth authentication issue with my Clover app. The app is built on Base44 (frontend + backend) and is approved by Clover, but during the OAuth flow I’m receiving “Invalid OAuth Credentials” errors when merchants attempt to connect their Clover account. This is not a beginner task — I need someone who has worked directly with Clover OAuth, production apps, and redirect URI debugging. Environment Clover POS Production App already approved in Clover Developer Dashboard Backend hosted on Base44 OAuth flow: Clover → Redirect URI → Token exchange The Issue OAuth authorization initiates correctly Clover redirects back to my app Token exchange fails with Invalid OAuth Credentials Redirect URI recently updated and needs verification Need to confirm: Client ID / Client Secret handling Redirect URI exact match OAuth token request format Base44 environment variables are not altering secrets Production vs sandbox credential mismatch What I Need Help With Review Clover OAuth configuration (production) Verify redirect URI and token exchange flow Identify why Clover is rejecting OAuth credentials Fix the issue so merchants can successfully connect Clover Optional: quick walkthrough explaining the fix
