Re: 404 error on accessing REST API ABAP

Isn't it OAuth2?

Your first HTTP request is to get the token.

Your second HTTP request is to run the API and it's 404 which means not found.

You say the second one returns 404 page not found, it means that the URL is invalid

https://zzzzzz.sharepoint.com/sites/galaxy/_api/Web/GetFileByServerRelativeUrl

Hi, 404 error means connection refused, if URL is wrong it will not be accessible even on first time, but as i mentioned i am able to access for the first time i am getting data from both of the the API's , but when i execute for second time the second url https://zzzzzz.sharepoint.com/sites/galaxy/_api/Web/GetFileByServerRelativeUrl returns 404 error 'Connection refused'

Re: 404 error on accessing REST API ABAP

Sandra_Rossi — Fri, 10 Mar 2023 08:53:11 GMT

Weird to have 404 page not found with a different error reason.

Usually it's 401 or 403 for login error or whatever.

HTTP 404 - Wikipedia

Anyway, did you try to do 3 requests, 1 to get a token followed by 2 calls to API?

get a token
call GetFileByServerRelativeUrl with token above
call again GetFileByServerRelativeUrl with same token

Does it work? (it should, because the token has a sufficient expiration time)

Hi sandra,

no it didn't work , still returning 404 connection refused

I guess you need to check Sharepoint API documentation, how to use it exactly.

You'd better ask in Microsoft-related forums, or Stack Overflow, or things like that.

Possibly, someone working on SAP product may also know.
