The essence is as follows. There is a site built on tilda. I connected CRM and various payments to the site ... In order to communicate with the API of payments, you need to send complex headers + BASE AUTH, the constructor's server, complex headers like Authorization blocks. I need to communicate with the merchants API - in order to pull up some info on the site for later sending to CRM, but I cannot do this because of the security policy of the server. Tell me some services, workarounds. Ie, I need to send the info from the site of the designer with a simple request for a third-party script that already has no problems with CORS, which will safely send the request with the information received further. Who has any considerations on this subject, are there any services for intermediate scripts on JS for the implementation of my wishes?
