Introduction
The CallBack URL feature allows you to record your transaction to your personal servers in real-time.
When a card transaction has been completed, Blink can send your transaction data to a URL, where it can be added to your database, develop custom notifications/ emails for your customers/ staff, update invoices etc… instantly; removing the need for exporting to CSV and uploading to your own software. As it is done a Callback function, it runs in the background and so your payment flows will stay as they are.
Important to bear in mind
It only works when the payment is made, cannot be used to pull previous transaction data.
It is only available for Card transactions, not Open Banking or Direct Debit Transactions.
The Callback URL will send all transactions, including declined transactions. Ecom transactions may be recorded multiple times due 3D-Secure authentication requirements.
A developer (junior-level) will may be needed to format the data.
