It looks like what you saw was a bug getting fixed, so sorry about that! The correct behaviour is that if you call get_app_origin() or get_api_origin() from an app in the Anvil editor, they’ll return a temporary development URL. If you’re running in the editor but you want to get the public URL of your app, call get_api_origin("published").
We’ve updated the docs to spell this out more clearly. Here’s the important part:
Sometimes you will want to generate URLs that point to your HTTP endpoints without having to hard-code the origin of your app. Instead of writing:
endpoint_url = "https://my-app.anvil.app/_/api/users"You can call
anvil.server.get_api_origin():
endpoint_url = anvil.server.get_api_origin() + "/users"This has the advantage of returning whichever origin the user is currently connected on, i.e. if you have published a version but you are running your development version in the Anvil editor,
get_api_origin()will return a temporary private link to your development version, so you can test your APIs before publishing them!If you’re running in the editor,
get_api_origin()might return a URL that’s private or not permanent. To get the origin for the published version of your app, callget_api_origin('published').
