Shopify Payment Not Working
Payment failures stop customers completing orders. This is a critical issue that requires immediate investigation. Payment failures can be caused by gateway configuration, API errors, or checkout-level issues that need technical resolution.
Common causes
- Payment gateway misconfigured or credentials expired
- Currency mismatch between store and gateway settings
- API key errors or gateway account suspended
- Checkout scripts interfering with payment submission
- 3D Secure or fraud protection blocking transactions
- Shopify Payments not supported in your region
Quick checks
- 01Log into your payment gateway dashboard and check for alerts
- 02Verify the gateway API credentials are current
- 03Confirm the store currency matches gateway configuration
- 04Test with a different payment method if available
- 05Check if the issue affects all customers or just some
When to get expert help
If the issue persists after completing these checks, deeper investigation is required. Complex issues often involve code-level conflicts that cannot be resolved without direct store access.
