Attribution in your app
Esri requires that when you use an ArcGIS Online basemap, Esri data services, or Esri API technology in your app you must also include Esri attribution. There are specific requirements for attribution you may be required to address in your app depending on how your app is built and the data it uses.
- Data attribution (basemaps, layers), when you use specific data hosted on ArcGIS Online that requires attribution.
- Esri attribution, using Powered by Esri, when your app is built with the ArcGIS API for JavaScript or uses data served by Esri through ArcGIS Online.
Display attribution on the map
When building your app with the ArcGIS API for JavaScript, both data and Esri attribution can easily be handled using the default implementation at the bottom of the map. This is the recommended placement, so apply it there if it works with your app design.
More information on attribution requirements can be found on the Attribution in your app page.
