Business Central Get Token SharePoint - sharepoint

Question

I'm trying to connect the business central with the sharepoint, I already did it in the postman, it worked fine, the GET and POST.
But now Im trying to do it on BC, the token is created but not working, I think it has some problem with the connection or the URL's.
codeunit 50100 "APISharePoint"
{
var
OAuth2: Codeunit OAuth2;
ClientIdTxt: Label '4d148348-137a-40e7-b20c-a458c2a03c65', Locked = true;
ClientSecret: Label 'Ai2pOhE7yeZ8WRxrwSrHdpVtNqJg51tg2X+s8CJDLy4=', Locked = true;
ResourceUrlTxt: Label 'https://crmbc384959.sharepoint.com', Locked = true;
OAuthAuthorityUrlTxt: Label 'https://login.microsoftonline.com/ec36749a-af47-4f04-892c-98666b6cac1b/oauth2/v2.0/token', Locked = true;
procedure GetAccessToken(): Text
var
PromptInteraction: Enum "Prompt Interaction";
AccessToken: Text;
AuthCodeError: Text;
RedirectURLTxt: Text;
begin
// OAuth2.GetDefaultRedirectURL(RedirectURLTxt);
RedirectURLTxt := 'https://localhost';
if OAuth2.AcquireTokenWithClientCredentials(ClientIdTxt, ClientSecret, OAuthAuthorityUrlTxt, RedirectURLTxt, ResourceURLTxt, AccessToken) then
exit(AccessToken)
else
exit('');
end;
procedure HttpGet(AccessToken: Text; Url: Text /*var JResponse: JsonObject*/): Boolean
var
Client: HttpClient;
Headers: HttpHeaders;
RequestMessage: HttpRequestMessage;
ResponseMessage: HttpResponseMessage;
RequestContent: HttpContent;
ResponseText: Text;
IsSucces: Boolean;
begin
Headers := Client.DefaultRequestHeaders();
Headers.Add('Authorization', StrSubstNo('Bearer %1', AccessToken));
Headers.Add('Accept', 'application/json;odata=verbose');
RequestMessage.Content.GetHeaders(Headers); //asd
Headers.Remove('Content-Type');
Headers.Add('Content-Type', 'application/json;odata=verbose');
RequestMessage.SetRequestUri(Url);
RequestMessage.Method := 'GET';
if Client.Send(RequestMessage, ResponseMessage) then
if ResponseMessage.IsSuccessStatusCode() then begin
if ResponseMessage.Content.ReadAs(ResponseText) then
IsSucces := true;
// end else
// ResponseMessage.Content.ReadAs(ResponseText);
// JResponse.ReadFrom(ResponseText);
exit(IsSucces);
end;
end;

Maybe your problem is the combination of GET with a request content.
As far as i know, the underlaying implementation of the HttpClient in .NET does not support GET with a request content. You can read more about it here: How to use HttpClient to send content in body of GET request?
Maybe you can try GET without setting the content-type on the content or use POST or PUT instead.
But you didn't supply a error message so this is just a guess.
