What's the modern way to request a 3rd party API?

Question

JavaScript

I have a Node JS server, I receive data from the client-server, that is, recursively from the client with a POST request by sending a token, my server interacts with the API of a third-party application and the client receives the next portion of json data, well, I think you understand.
But this is slow, every time you receive a token on the client and return it, is there something more modern, fellow programmers? I understand that it is impossible to shift the request recursion to the server, there can be a lot of data. Maybe there are some examples
