I'm getting this 400 error when attempting to send a test notification. The customer is unable to see any traffic on the Dynatrace side, would there be a way to troubleshoot this error?</P> Thu, 18 Dec 2025 13:47:04 GMT dan_reed 2025-12-18T13:47:04Z https://community.dynatrace.com/t5/Alerting/Apigee-Custom-Integration-0Auth2-Invalid-Request-error/m-p/281786#M5761 <P>Trying to troubleshoot this custom integration error with apigee.

I am not familiar with Apigee's oAuth scheme, but I would recommend verifying that the oAuth settings on the Dynatrace side [see screenshot] are fully compliant with what Apigee needs to see on its side.</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="marco_irmer_0-1753206884730.png" style="width: 400px;"><img src="https://community.dynatrace.com/t5/image/serverpage/image-id/29140i23E0331B52CC8ED1/image-size/medium?v=v2&amp;px=400" role="button" title="marco_irmer_0-1753206884730.png" alt="marco_irmer_0-1753206884730.png" /></span></P><P>I hope that helps.</P> Tue, 22 Jul 2025 17:54:58 GMT https://community.dynatrace.com/t5/Alerting/Apigee-Custom-Integration-0Auth2-Invalid-Request-error/m-p/282084#M5772 marco_irmer 2025-07-22T17:54:58Z
