Hi everyone,
I’m working on integrating a third-party service with ServiceNow. The third-party stores their data in AWS, and I’m trying to make a REST call to their URL from ServiceNow. However, I keep encountering this error:
"Only one auth mechanism allowed; only the X-Amz-Algorithm query parameter, Signature query string parameter, or the Authorization header should be specified."
I'm hitting the URL provided by the third-party app, and I’m able to get the attachment successfully when I use Postman. However, the same request is not working when I try it using a ServiceNow outbound REST message.
I’ve ensured that the authentication mechanism is set up properly, but I’m still facing this issue. Has anyone experienced a similar problem or could provide some insights into why this might be happening in ServiceNow but works fine in Postman?
Any suggestions or guidance would be greatly appreciated. Thanks!
