I'm trying to create a flow in Power Apps that will call an API which uses HMAC auth. I can't, for the life of me, figure out how to do this with Power Automate I have an Appid and AppKey provided by the API authors, but I'm not sure where to put those and I don't see a way to generate the token. Right now I have a flow that uses an HTTP post trigger. Please help!
hi @xChristine7714 I try firstable in Postman to see if the values are ok, In HTTP you need to know what headers needs the API and in body what are the parameter are needed I give you and example about how to send Bearer token in HTTP.
This example is for Dynamics.
you can contact me at email@example.com to do a Teams call if you want.
If you want to skip the Power Automate part and do the authentication and utilise the external service in Power Apps only, you can create a custom connector for it and that will save the flow runs. You can check here for more details on getting started to create a custom connector: https://docs.microsoft.com/en-us/connectors/custom-connectors/
Hope this Helps!
