Connect with service principal

[matejskubic]

Is your feature request related to a problem? Please describe.
Custom connector should provide an option to connect with service principal credentials.

Describe the solution you'd like
Like other standard connectors provides option to connect with service principal credentials.

Describe alternatives you've considered
Already tried in swagger editor to change flow from accessCode to application. After Update connector action oauth2 flow is changed back to accessCode.

Sample yaml:

securityDefinitions:
  oauth2_auth:
    type: oauth2
    flow: application 
    tokenUrl: https://login.microsoftonline.com/common/oauth2/token

Additional context
Custom connector should provide connectivity without user context (aka service-to-service communication) and application permission (not delegated).

With Azure AD we have figured it out, however this doesn't work with generic OAuth2 provider. If your case is AAD, I can share the solution - however it is not officially supported by Microsoft.

By the way, we just released a token-proxy to enable client_credentials flow via Azure Functions, feel free to use it: https://github.com/TALXIS/token-proxy

Thanks @hajekj for the response. Please note that we have a forum as well which might be a better option get some answers for issues that are NOT related to certified connector and paconn cli. https://powerusers.microsoft.com/t5/General-Power-Automate/bd-p/MPAForum

This is now on roadmap as part of Release Wave 1 2022: https://docs.microsoft.com/en-us/power-platform-release-plan/2022wave1/power-platform-pro-development/service-principal-support-connectors

Did this ever get released in Release Wave 1 2022? I look at their documentation and do not see anything about support for service principals in custom connectors.

Is there any update about this feature? There is no support on custom connectors yet to use service principals

Is there any updated on this? It still doesn't appear to be possible to use service principals / client credentials flow with custom connectors.

Yes, this is now in preview - https://powerapps.microsoft.com/en-us/blog/public-preview-of-new-custom-connector-enhancements/
