API calls from a PCF component - premium?

Posted on by ThorsteinnAsg

Hi everyone,

My team has been working on implementing API calls from a PCF component for a Canvas App. Are we at risk of violating licencing policy and/or making the app become premium at some point, possibly without us noticing? If so this would affect our client in a major way, any insights or thoughts are much appreciated. Thanks.

No, this is not a licensing issue. But you should expect to hit CORS issues, so be sure that the systems you are calling will support cross-origin calls.

Hi @ThorsteinnAsg ,

A few thoughts on this.

Here are the PCF docs, where are a few Licensing sentences: https://learn.microsoft.com/en-us/power-apps/developer/component-framework/overview?WT.mc_id=BA-MVP-5004107#licensing

There is stated:

"Code components that connect to external services or data directly via the user's browser client and not through connectors are considered as premium. When these components are used in an app, the app becomes premium, and end-users are required to have Power Apps licenses."

On the other side, I understand that the PCFs need to declare "external-service-usage" in order to be considered premium (and there declare the domain).

<external-service-usage enabled="true"> <domain>www.microsoft.com</domain> </external-service-usage>

My thoughts on this: I understand that you don't want to declare it as premium, and that is working right now. I'm not sure if the guards are implemented already, or if it's possible to have issues in the future (like the connection being blocked because it's not declared...). . But these are just my thoughts.

Hi Diana,

What remains unclear to me is the term "external" in this context. Probably up for interpretation in each implementation.
