An expired API key can cause significant disruptions in payment processing by failing to authenticate transactions between your WooCommerce store and the payment gateway. Recognizing and addressing this issue promptly is crucial to ensuring seamless transaction operations.

This guide will help you understand the error messages associated with an expired API key, identify possible causes, and follow step-by-step troubleshooting measures to resolve the issue efficiently.

Error Message for an Expired API Key

The error message related to an expired API key may include phrases such as “Authentication Failed – Expired API Key,” “Invalid API Key – Expired,” or a similar indication that the API key used for authentication has passed its expiration date.

An expired API key can disrupt payment processing as it serves as a crucial authentication credential between the merchant’s system and the payment gateway. Without a valid and up-to-date API key, transactions cannot be successfully authorized and processed.

Possible Causes

Incorrect Entry: The API key may be expired if it was entered incorrectly in the payment gateway settings on your WordPress dashboard.

Disconnected Account: If your account with the payment gateway is disconnected or deactivated, it can lead to the expiration of the associated API key.

Troubleshooting Steps

Log into Payment Gateway:

Log in to your payment gateway account and locate the API key section in your payment gateway account.

Generate New Keys:

Follow the provider’s instructions to generate new API keys.

Update WooCommerce:

Go to WooCommerce settings and replace the old API key with the new one. Save the changes in WooCommerce settings.

Monitor Expiry:

Regularly check and renew API keys before they expire.

Document and Secure API Keys:

Keep a secure record of your API keys and credentials.
