How do I license the use of Basemap-Layer in a javascript app?

[LukasKoerdt]

Hi,

I want to switch to esri-leaflet and have a developer account at ArcGIS for Developers.

I want to upgrade my account to a paid one, before distributing the app.

I was using Mapbox so far and had to pass my API key before creating a basemap.

My question is how do I do that with esri JS-API? I could't find any resources on this topic.

I'm able to create a map with L.esri.basemapLayer("Streets").addTo(map); and it works perfectly. Why don't I need to pass my credentials so I can be charged for the use?

Thanks in advance
