Read timed out - End of Day price data

Requirements: We want End of Day price from DSS
Technology : Salesforce
DSS REST API Service : https://hosted.datascopeapi.reuters.com/RestApi/v1/Extractions/ExtractWithNotes
Issue : System.CalloutException: Read timed out
Expected API: Instead of timeout can you send us ExtractionID and Data "Example: ExtractionId='0x053b21c6eadb5821'" as a response body. we will retrieve data from DSS REST AOU "ExtractResult(ExtractionId='0x053b21c6eadb5821'


Sample code


request.setTimeout(120000); //Maximum in milliseconds
request.setMethod('POST');
request.setHeader('Content-Type', 'application/json');
request.setHeader('Prefer','respond-async');
request.setHeader('Authorization',userAuthResponseSessionToken);
HttpResponse response = http.send(request); //Getting Timeout from DSS
system.debug('Status Code is '+response.getStatusCode()); //Exception thorwn above line, hence don't get status code here as 202 Accepted or 200 etc
String resultBody = response.getBody();
System.debug(Logginglevel.DEBUG,response.getBody());

@abhishek.tripathi, could you please:

  • Post the full body of your POST request ? (This can be done as an attachment if it is large)
  • Tell us if the timeout happens systematically or only occasionally ?

That would help us debug the issue you are facing.

Answer by Veerapath, copied here to be able to close the thread:

The error indicates that the value in the Authorization header is incorrect. The Authorization header needs to start with "Token" string. Please modify the code as follows.

request.setHeader('Authorization','Token'+ usrAuthResponseSession);

Hi @abhishek.tripathi,

The ExtractWithNotes requires request's body. From the code, I cannot see the .setBody() method. Could you verify and add the body of the request?
