CHALLENGE #2 – Geocode customers (LEVEL 3)


As customers are created or modified, their addresses are automatically geocoded and their location are stored in a set of new fields on the Customer table. A factbox showing the current location of the customer on a map is added to the Customer Card and links to open a large map or get directions are available as well. As a bonus, you can create an action, which will display all customers within a certain range on a map.

To complete this challenge, you will need

  • A Dynamics 365 Business Central Sandbox Environment
  • Visual Studio Code with the AL Extension installed
    • Azure VMs will have VS Code pre-installed
  • A BingMaps API Key from (Public WebSite or Dev/Test key)

Expected result


  • Create an empty app
  • Create a table extension for the customer table and add fields
  • Create a page extension for the customer card and add fields
  • On the OnBeforeModify and OnBeforeInsert triggers on the Customer table, geocode the customer address using BingMaps API
  • Create a CardPart page showing a map of the geocoded position
  • Create an action opening a browser with all customers as shared places


  • In VS Code, use Ctrl+Shift+P and type AL GO and remove the customerlist page extension
  • Use the ttableext, the tfield and the tkey snippets
  • Use the tpageext and the tpagefield snippets
  • Use HttpClient to communicate with the Web Service and use Json types (JsonObject, JsonToken, JsonArray and JsonValue) to extract values from the Web Service result
  • Use tpage snippet and add usercontrol with the WebPageViewer. Use to see the html you can use In the control.
