API integration with google sheet, Yukassa and 2 banks

The site is self-written. You need integration with google sheet and several payment cards.

1 - Pass user data from the pop-up form to google sheets via webhook. The registration form is drawn up and uploaded to the site. You only need integration into a specific google sheet. More details in the tk in the attachment.

2 - Connect to the payment page widget yukassa and 2 installments of banks (sber and tks). Everyone gives ready-made scripts. The payment page is already laid out. All that is needed is integration. All keys for api and access are available. Links and more details in the attachment.

I am looking for experienced programmers who have worked with such tasks. Perfectly full stack.

Write in the comments the timing and budget.
