Question

API

When sending a get request according to the API documentation to the server, it returns a 404 error, although when you go to this link in the browser, the xml opens according to the documentation. Other requests go through, I can get data about the device, the user, but the device profiles do not work. prompt with what it can be connected?

Answer 1

give an example of the get request you are sending.
give an example of the full answer you get in return.
provide a link to the documentation for the API.
then it will be possible to talk in detail, but for now, with the available information about the problem, it will be fortune-telling on coffee grounds.

Answer 2

Sending request incorrectly

Answer 3

The problem may be that you are sending a request with http and you need with https or vice versa.

Answer 4

Even in my practice, in particular, there was such a reaction to the absence of a User-Agent

Answer 5

Are you sending an Accept header?
If you're sending something like application/xml, then try sending text/html (which is often what the browser sends).
