AL CodeUnit API scope

Posted on by NW-02041031-0

We know that an AL Page can contain the line PageType = API; and a Query can contain: QueryType = API; so that a Web Service can be wrapped around them in Business Central and then be accessed from external software like Microsoft PowerApps (via a connection) or C#.NET (via an oData Connected Service). Can a CodeUnit contain a line like: CodeUnitType = API, for the same reason?

Alternatively can a procedure be defined in an API Page and then be called from external software?

I seem to be always posting on both forums because I'm working on a project that involves PowerApps interacting with Business Central (On-Prem). Here's a related PowerApps question: if we were to be able to define either an API scope CodeUnit or an API scope procedure within an API Page, can PowerApps call it?

Hi @NW-PA ,

Do you want to call a external API from your PowerApps app directly?

If you want to call a external API from your PowerApps app directly, I afraid that there is no way to achieve your needs in PowerApps currently.

If you want to call a REST API from PowerApps app, I think the Custom connector functionality could achieve your needs. You could consider define a Custom Connector within your PowerApps based on your external REST API, then you could call your external REST API through this Custom connector.

Note: The SOAP API is not supported within PowerApps currently, only REST API is supported.

More details about creating a Custom connector based on REST API within PowerApps, please refer to the following article:

https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/register-custom-api

Also please check and see if the following video resource would help in your scenario:
