API endpoints adhere to the general format below:
<url>/<api_version>/<entity>/<verb>
As an example, the API endpoint to create a campaign is the following:
https://ads.nextdoor.com/v2/api/campaign/create
Some endpoints require a resource id (e.g. campaigns, ad groups, etc.). In those cases, the resource id is the last path element of the URL:
https://ads.nextdoor.com/v2/api/campaign/get/123456789
