Sophos Central API Testing with Swagger

Question

I have recently began testing the Sophos API for Sophos central. 
 
 I have created an API key within the Sophos Central Console 
 
 And using this , I have downloaded the Central SEIM Integration script and I have been able to execute the file script successfully. 
 community.sophos.com/.../125169 
 
 However, I now want to see what other capabilities the API offers. 
 I have followed the instructions in the following doc. 
 community.sophos.com/.../125398 
 
 When I try and test any of the API commands I get errors. 
 I have no changed the API is any way, however testing any individual command from within the Swagger Editor fails. 
 Its intimates that the error may well be a "cross origin call issue", but the KB article does not provide any information on whether the Sophos server allows this and if not, how to test with the Swagger editor. _ I feel that the documentation is missing some additional instructions to get this to work. 
 Has anyone managed to get any API commands to work within the swagger editor ? 
 
 Any advice would be welcome.

For reference for anyone else trying to do more with the API. 
 Use swagger only as an api doumentation/interpretation tool. 
 Any attempt to call/test the api direct from the swagger interface fails, due to a cross-origin-call issue. 
 Solution: - use Postman API Runner plugin for Chrome. 
 Sample below enumerates endpoints using http://api1.central.sophos.com/gateway/migration-tool/v1/endpoints 
 Create Authorization Key and x-api-key and enter values generated within Sophos Central fro client. 
 ** important** include the whole of the Authorization key including the word Basic otherwise it will fail 
 Hope this helps someone else
