Overview
Version 3 of the ActiveCampaign API is structured around REST, HTTP, and JSON. API endpoint URLs are organized
around resources, such as contacts or deals. It uses HTTP methods for indicating the action to take on a resource,
and HTTP status codes for expressing error states. Resources are represented in JSON following a conventional
schema.
Version 1 of our API is still available here. We have no plans to sunset version 1 of our API at this time and if we
ever do, we will provide plenty of advance notice to our community.

All requests to the API are authenticated by providing your API key. The API key should be provided as an HTTP
header named Api-Token.
Example:
Account name: 123456demo.activehosted.com
API Token: 123abc-def-ghi
