- WooCommerce installed and activated
- PHP 7.2 or higher
- A Credo account with API credentials

Search for "Credo WooCommerce Payment Gateway" and click Install Now.
After installation completes, click Activate Plugin.
Configuration
Get your API credentials
- Log in to your Credo dashboard
- Go to Settings > Developer > API Keys

Configure the plugin
- In WordPress, go to WooCommerce > Settings > Payments
- Find Credo Payment Gateway and click Manage
- Configure the following settings:
| Setting | Description |

Testing
Enable test mode
- Go to WooCommerce > Settings > Payments > Credo
- Set Transaction Mode to Test Mode
- Enter your sandbox API keys
- Save changes
Run a test transaction
- Add a product to your cart and proceed to checkout
- Select Credo as the payment method
- Complete payment using test card details
- Verify the order status updates to "Processing" or "Completed"
Switch to live
Once testing is complete:
- Change Transaction Mode to Live Mode
- Replace sandbox keys with live API keys
- Save changes
Webhook setup (recommended)
To ensure order statuses update reliably—even with poor network connections—configure a webhook:
Copy the webhook URL shown in red at the top of your Credo settings page.
Log in to your Credo dashboard.
Go to Settings > Webhooks and paste the URL.
Save the webhook configuration.
Troubleshooting
Credo doesn't appear at checkout
- Check that Enable/Disable is toggled on
- Verify both API keys are entered correctly
- Ensure you've clicked Save Changes
- Clear any caching plugins
Payments failing in test mode
- Confirm you're using sandbox API keys (not live keys)
- Check that Transaction Mode is set to Test Mode
- Use the correct test card numbers
Orders not updating after payment
- Verify your webhook URL is configured in the Credo dashboard
- Check that your server can receive POST requests from external sources
- Review WooCommerce logs for webhook errors
