API Connections – Dataverse with Client Certificate Authentication Issue on Logic App

Kumar Rathinam 20 Microsoft Employee

We are using the Dataverse connector in both Power Apps and Logic Apps.

We were able to successfully configure the Dataverse connector using client certificate authentication in Power Apps. However, the same configuration fails in Logic Apps.

The following error is displayed in the API Connections section when attempting to use client certificate authentication in Logic Apps same auth working fine on PowerApps :

I think that LA never reaches the dv mTLS broker at all… its conn stack routes cert‑auth thru the old ARM handler, so the chain dies before the STS handshake even starts. only way i’ve kept it alive was slidin an aad‑app shim so LA talks to that hop instead… dv’s cert path just won’t negotiate on LA’s transport layer I think.

Hi @Kumar Rathinam,

Thanks for the confirmation. Glad the issue is resolved.

The issue occurred because the connection in Logic Apps was created using a .pfx certificate without a password.

Although the same certificate authentication was working in Power Apps, Logic Apps requires the .pfx certificate to have a password during connection creation.

To resolve the issue:

Generated new .pfx certificates with passwords for both Dev and Prod environments.
After using the password-protected certificates, the connection was recreated in API Connections.

The Dataverse connector was successfully configured in Logic Apps using client certificate authentication, and the connection started working as expected.

Hope this helps!
