PayPal Verification Skill

This skill provides a way to verify that your PayPal environment variables are correctly configured and that the API connection is healthy.

Usage

Run the verification script to check your local and production-ready credentials:

bash
node skills/paypal-verify/scripts/verify-env.js

What it Checks

  1. •Hidden Characters: Detects trailing newlines or spaces in Client IDs and Secrets (a common cause of invalid_client errors).
  2. •Environment Match: Ensures you are using Sandbox IDs with the Sandbox URL, or Live IDs with the Live URL.
  3. •Token Validation: Attempts to fetch an actual OAuth2 token from PayPal to prove the credentials work.

Common Fixes

If you see an "Invalid Client" error:

  • •Run node skills/paypal-verify/scripts/verify-env.js to see if a newline is detected.
  • •Use the sync-local-env-to-vercel.sh script to re-upload keys using printf which strips newlines.
  • •Ensure PAYPAL_ENVIRONMENT is exactly LIVE or SANDBOX.
