Every time I send an on demand extraction request, I get a 404 response. Any help would be appreciated. Thank you.

I've formatted the request as below:

method:

POST

URL:

https://hosted.datascopeapi.reuters.com/RestApi/v1/Extractions/ExtractWithNotes

header

{ 'Authorization': u'Token <token>', 'Content-Type': 'application/json', 'Prefer': 'respond-async' }

content

{ '@data.type': '#ThomsonReuters.Dss.Api.Extractions.ExtractionRequests.CompositeExtractionRequest', 'ContentFieldNames': [ 'RIC', 'CUSIP'], 'IdentifierList': { '@data.type': 'ThomsonReuters.Dss.Api.Extractions.ExtractionRequests.InstrumentIdentifierList', 'InstrumentIdentifiers': [ { 'Identifier': 'IBM.N', 'IdentifierType': 'Ric' }, { 'Identifier': 'AAPL.O', 'IdentifierType': 'Ric' } ], 'UseUserPreferencesForValidationOptions': 'false', 'ValidationOptions': 'null'} }

Thank you for replying so quickly to my question. I based my request on the sample found in the tutorials. From what I can tell, my URL is the same as the one shown and that I was in fact sending a POST request. Adding instrument list, getting instrument lists, and deleting instrument list work for me. Are there anything else I could be missing?

I received a succesful code with the test using Postman.

Tried it on Postman. Got it to work. Went back to the code, apparently I added an excessive "https://hosted.datascopeapi.reuters.com/RestApi/v1" and was printing it out and the wrong place so it looked right... Thanks again for your help.
