Website token, how to get/parse it correctly?

Question

PHP

Good day to all!
On the website of the payment gateway, when requesting the calculation of the commission for sending from card to card, the following data is sent: sPan, rPan, amount, and, in fact, the token. The question is how it can be obtained/generated and so on. I tried to search in the page code, but there is a completely different token. I apologize in advance if this is a stupid question.
PS Screenshots for clarity:

naturally different, it changes with each sending, and judging by the fact that you are parsing something there, you obviously wandered somewhere in the wrong place
