How to get liqpay payment status via php?

Question

PHP

There was a problem.
The person using the payment link fills in the amount and pays. Through callback I can get two POST parameters - data and signature. How to extract payment data from them? For example, I need to find out the amount that a person paid. The documentation is not clear at all. If possible, please post an example.

Answer 1

Read the liqpay documentation normally, everything is perfectly described there. In the callback you get data and signature, data is an array with information about the payment in base64 format, therefore, first you do a signature check, for this you need to read it

$sign = base64_encode( sha1( 
$private_key .  
$data . 
$private_key 
, 1 ));

And compare if your sign is equal to the received signature, then the request is valid.
Here is the link to the doc

Answer 2

if possible, ask support

Answer 3

I already understood. I just needed to decode base64 and everything is fine.
