Question

I have used a redirect method of payment using PHP. Can any one help with the callback file content?

I don't know what to define in callback.php file. I can't find any help from any source. I have already refereed below link about callback in dibs http://tech.dibspayment.com/DX/Hosted/Output_parameters/Return_pages

Answer 1

You need to understand that callbackUrl is a parameter which same as others cancelReturnUrl and acceptReturnUrl parameters. Short description from your references

acceptReturnUrl

Upon returning to acceptReturnUrl, the customer will normally expect a receipt to be displayed.

cancelReturnUrl

In case the customer cancels the purchase using the functionality in the payment window (not by closing the window), he is returned to the cancelReturnUrl

callbackUrl

When the customer finishes a payment, he is redirected to the acceptReturnUrl along with the return parameters. If the customer stops the communication (closes the browser, loses internet connection ect.) before reaching the webshop, the shop system is not informed of the result of the purchase. To avoid this situation, an automatic server-to-server call can be sent to the shop backend, enabled by sending along the "callbackUrl" parameter. This URL is then automatically called with the return parameters when the purchase is accepted.

The call is created as a post. All the previously described return parameters are returned to the callbackUrl, and it accepts only port 80 (HTTP), 443 (HTTPS ) and 20080.

Because http is a stateless protocol which means that the connection between the browser and the server is lost once the transaction ends. To solve this problem your payment gateway(DIBS) suggest to use callbackUrl parameter, give an url to this parameter which is listened at your side. If any problem occur like mentioned in the case (closes the browser, loses internet connection ect.) DIBS will return this url address which mentioned at your callbackUrl parameter with payment return parameters.

So at backend you can update your payment information.
