Extract

When to use extract

Section titled “When to use extract”

Use extract when you need GeoJSON features near a point within a mile radius you choose—for example loading nearby boundaries for map display or downstream processing.

Lookup answers “which feature contains this point?” Extract returns a collection of features in an area.

Request

Section titled “Request”

Provide lat, long, service (one layer name from your key), and radius parameters as defined in your service OpenAPI document. Import that service’s spec via OpenAPI import—field names are not identical across all layers.

Response

Section titled “Response”

A GeoJSON feature collection suitable for map clients or transformation in Apex. When calling from Salesforce via External Service, validate field paths against the imported schema in Flow debug.

Salesforce notes

Section titled “Salesforce notes”
  • Uses the same Three_Levers_API Named Credential and ApiKey principal as lookup.
  • Separate External Service import if your licensed extract operations live on a different Swagger document than lookup-only services.
  • Large responses may affect Flow heap limits—filter or process in Apex for very dense areas.
