Use this guide to understand what happens to the API requests after the expiry of the free trial/subscription to the web application QR API.
Initially, while Signing up for the QR API tool, there were 20 Free API requests to test the tool. Now when the first 20 requests are utilized or the free trial period expires, the API key will become invalid. This also happens while the user is subscribed to any plan (BASIC, STANDARD, PRO, ENTERPRISE) and the plan validity expires.
Now, when the system or mobile app sends an API Request with an invalid key, a QR Code image with a preview watermark will be returned.
Such QR Codes are unscannable by most QR Code scanning apps.
To activate the API key, log in to the account and start/reactivate the subscription.
