I'm just getting into looking at how to create a Custom API. I have a few questions to see if you can point me into the right direction.

1. Using VSCode with the AL extension at some point the new tables and code need to be published.

Where do the tables and AL code get published to. In order words what environment onPrem or Cloud does the code get executed from?

Right now I'm using the free BC cloud version.

Thanks,

Dave

You have to upload the app file to environment that you want once you have completed your custom API created and App file generated in VS Code.

Hi,

The code will execute from the environment where you publish and install your extension.

If you install extension in SaaS it will run from SaaS otherwise if you install extension in on Prem it will run from on Prem environment.

You have to upload your AL code as an extension into the cloud version of BC. If its a sandbox environment you can upload the extension directly from VSCode or by uploading the extension .app file in the application, if its a production environment - you have to upload it using the .app file.

Hi, If you are using the free BC cloud version and publish directly from VS Code, it will be installed to the environment specified in the launch.json file.

For example,

You can find it on the page below once it is installed.

Hope this helps.

Thanks.
