Troubleshooting - Alignet Integration Docs

1. Common Errors table

Identifies the symptoms and applying the recommended solution:

Problem	probable cause	Suggested solution
No Loading Form	Invalid credentials or wrong environment.	Check that the Merchant ID and the Keys match the mode (Sandboxproduction).
Successful payment without order	The Webhole (S2S) was unable to notify your store.	Validate that you URL S2S be public and check if a Firewall or Security Plugin blocks the IP from Alignet One.
Failed billing data	Mandatory fields are missing from check out.	Make sure that the client complete name, name, email and phone.
Reversal doesn’t work.	The transaction doesn’t allow refunds yet.	Check that the original transaction is in status Liquid. Payments on the same day do not always allow for an immediate reverting.
Payment button doesn’t appear	JavaScript conflict or SSL absent.	Check the browser console (F12) and be sure to navigate by HTTPS.

2. Technical Diagnosis (Logs)

The plugin records every relevant interaction. If a payment fails “quietly,” the logs will tell you why.

Go to WooCommerce > State > Loks.

At the right drop-down, look for the file that starts with payme- checkout-… and give them to See.

Search for lines that contain ERROR or RESPONSE. That’s where you’ll see the processor’s response code (Visa / Mastercard).

Can compare the error codes found in the login with our Response Codes Guide.

3. Server Verification

To have the plugin communicated with the gateway correctly Alignet One, your server should allow:

Data output: Connections to the URLs of API of Alignet One (Port 443).

Data entry (S2S): Your server should accept requests POST Exstore.

Extensions PHP: Check that curl and openssl are active in your PHP.
