Validating a Key

Using WC Key Manager, you can easily verify whether a license key is valid or not. If you are selling software and want to validate a license is still valid after it has been activated.
Checking if a license is valid and not expired is very similar to activating a license key.

Validating a license key is a straightforward process. You need to send a GET/POST request to the Licensing API endpoint like this:

https://example.com?wckm-api=validate_key&key=YOUR_LICENSE

Parameters

Parameter	Description
key	The license key that you want to activate.
label	The unique string to reference the activation.
product_id	(Optional) The key will automatically detect the product ID if not provided.
email	(Optional) The email address of the user who purchased the product.

Example Response:
The response for this request will be a JSON object. If the license key is valid, the response will be:

{
  "success": true,
  "message": "Key is valid.",
  "activation_limit": 0,
  "activation_count": 0,
  "activation_remaining": "unlimited",
  "expires": "never",
  "order_id": 139,
  "customer_name": "Antoinette Mraz",
  "customer_email": "[email protected]",
  "checksum": "ab142974d13a28dc5da2321a705df0d6"
}

If you pass the label parameter, the API will validate the license key against the label and returns the status of that activation, the response will be:

{
  "success": true,
  "message": "Key is valid.",
  "activation_limit": 0,
  "activation_count": 0,
  "activation_remaining": "unlimited",
  "expires": "never",
  "order_id": 139,
  "customer_name": "Antoinette Mraz",
  "customer_email": "[email protected]",
  "checksum": "ec0728cdd0eac85ba65b3e13905233d9",
  "label": "Hello",
  "label_status": "inactive"
}

If the license is invalid, the response will be:

{
  "success": false,
  "error": "invalid_key",
  "message": "Invalid key, please provide a valid key."
}

Possible errors:

invalid_key	When the key is empty or invalid.
missing_label	When the label is empty or invalid.
invalid_product	When the product ID provided but does not match with the key.
