helloworld.go - How to run GoLang Sample Code using the Hello World API and Mutual SSL

[shameem]

Hi @murotovb ,

Looks like you have made few changes to the code which we have provided on the forum. 

I would request you to try with our code without any modifications except replacing the placeholders.

If you still unable to get it running, share with us the "X-Correlation-ID".  You can print it by adding the line at the end.

log.Println("Response Header:", resp.Header.Get("X-Correlation-ID"))

Thank you.

Hi @shameem,

I've tried with the sample code without any modification. Still have the same error.

X-Correlation-ID: 1718275730_365_1219024619_-546f65b8c9_VDP_WS

Hi @murotovb,

Please provide the following information, in text (not screenshot) so that I can copy/paste the information for engineering. Thanks.

1. End Point
2. Request Header
3. Request Body
4. Response Header (include the x-correlation-id)
5. Response Body

You can find the x-correlation-id in the response header.

Hi @API_Products,

The problem is not related to wrong URL or payload.

If I add spaces in URL I'm getting the following error:
