Troubleshooting Connection Issues

If you're experiencing problems connecting your Stripe account to the plugin, this guide covers the most common issues and their solutions.

Connection Test Fails​

Server Firewall Blocking Requests​

Symptoms: Connection test fails even with correct API keys Cause: Your hosting provider has a firewall that blocks outbound requests to Stripe's servers

Contact your hosting provider to whitelist api.stripe.com.

Incorrect API Keys​

Symptoms: "Invalid API key" error during connection test Cause: Wrong keys entered or keys from different mode (live vs test)

Verify you're using the correct keys for your current mode:

  • For Test mode: Use keys that start with pk_test_ and sk_test_
  • For Live mode: Use keys that start with pk_live_ and sk_live_

oAuth Connection Problems​

PHP Error During Redirect​

Symptoms: PHP error occurs when redirecting from Stripe back to your API Settings page Cause: Webserver settings filtering request parameters

If you encounter a PHP error during the redirect from Stripe to your API Settings page, this could be caused by your webserver settings. Some webservers are setup to filter request parameters.
