but now the result is like

of course i try with token but need a clear url get/post to obtain data, this is because need obtaind data from a thirt party (excel like) data.

how to manage or create this request idealy without programing?

If you need the JSON,

You should be trying the following url in your browser:

yourerpsite/api/resource/Customer

Would suggest going through the right resources:

https://frappeframework.com/docs/user/en/guides/integration/rest_api#rest

https://frappeframework.com/docs/user/en/guides/integration/rest_api/listing_documents

https://frappeframework.com/docs/user/en/guides/integration/rest_api/manipulating_documents

i try exactly as described but every request return
Server Error

unknow if is my install, i try with 2 more servers.

ok i think the problem is because api is Case Sensitive, if use name exactly title work fine in mayor times.

tanks.
