Global with sharing class DocGeneration {

public static String Callout(){;
String resbody;
Http http = new Http();
HttpRequest req = new HttpRequest();
req.setEndpoint('callout:Tooling_API/services/data/v35.0/tooling/query/?q=Select+Id+from+Layout');
req.setMethod('GET');
req.setHeader('Content-Type', 'application/json;charset=UTF-8');
system.debug('req:' + req);
HttpResponse res = new HttpResponse();
res = http.send(req);
resbody= res.getBody();
system.debug('res:' + resbody);
return resbody;
}
}
When I am calling this method from annonymous Apex in developer console, It is returning the status as 200 but HTTPResponse has no body.Am I doing anything wrong? Please help.
I made some changes in your code. As I have ran the code in classic so I used my org's Instance url and ans Session Id as below and I got response in the assert.
String resbody; Http http = new Http(); HttpRequest req = new HttpRequest(); req.setEndpoint(URL.getSalesforceBaseUrl().toExternalForm()+'/services/data/v35.0/tooling/query/?q=Select+Id+from+Layout'); req.setMethod('GET'); req.setHeader( 'Authorization', 'Bearer '+userInfo.getSessionId() ); req.setHeader('Content-Type', 'application/json;charset=UTF-8'); system.debug('req:' + req); HttpResponse res = new HttpResponse(); res = http.send(req); resbody= res.getBody(); system.assert(false, 'res:' + resbody);You said you are also getting the code 200 which means your authentication is successfully performing. I would suggest you to assert the response and execute the code in execute annonymous.
Please try and let me know the results.

I can see the result but I am unable to store it in a string. Is there any way? Thanks in advance
