Client Credential Flow in power automate

[johnjohn123]

We want to call 3rd party API, the 3rd party API follow the Client Credential flow as per this document:-

https://auth0.com/docs/get-started/authentication-and-authorization-flow/client-credentials-flow

so how we can call this API inside our Power Automate flow? i tried to create a custom connector, but seems custom connectors does not support Client Credential flows.. any advice?

Thanks

hi @johnjohn123  I think you can use this guide How to create a custom connector in power automate with Graph API #PowerAutomate #GraphAPI - YouTube

I am experiencing a similar issue. The above mentioned YouTube video didn't address it. According to Swagger documentation, clientCredentials is a valid flow type, but when I try to edit the flow value in the custom connector Swagger Editor, I get an error:

Structural error at securityDefinitions.oauth2_auth.flow
should be equal to one of the allowed values
allowedValues: implicit, password, application, accessCode

The accessCode flow seems to be the closest option to a clientCredentials flow, but it doesn't seem to work with the API I'm working with.

Since many automations effectively serve as middleware to quickly connect two systems and possibly introduce some business logic or data transformation, incorporating the clientCredentials option seems like a valuable feature moving forward.
