If you have an application you would like to use the API with or your developer has requested your API details you can get them from within your admin area.

In your admin area go to "Account Details" -> "API Access"

Click the button "(Re)Generate API Key". This will create a unique API key for your store.

You will need to provide both the Company ID and the API Key when accessing the API for security reasons.

If you wish to revoke an applications access to your store API simply repeat the process above to generate a new API Key. The old key will be instantly deactivated once the new key is generated.
