Build API Access

An objective-c macOS/tvOS/iOS library for impCentral API access

Latest Release: 3.3.0


About BuildAPIAccess

BuildAPIAccess is an Objective-C (macOS, iOS and tvOS) wrapper for Electric Imp’s impCentral™ API. It is called BuildAPIAccess for historical reasons: it was written to the support Electric Imp’s Build API, the predecessor to the impCentral API.

BuildAPIAccess requires the (included) classes Connexion, Token and LogStreamEvent. All three are convenience classes for combining properties.

  • Connexion combines an NSURLSession instance and associated impCentral API connection data.
  • Token is used to store impCentral API authorization data.
  • LogStreamEvent is a packaging object for Server-Sent Events (SSE) issued by the impCentral API’s logging system.

API Usage and Methods

Please see the Read Me on GitHub for a full API listing.

HTTP User Agent

BuildAPIAccess issues HTTPS requests with a custom user agent string of the following form:


impCentral API Authorization

Making use of the impCentral API requires an Electric Imp account. You will need your account username and password to authorize calls to the API. These are passed into the login: method. BuildAPIAccess instances do not maintain a permanent record of the selected account; this is the task of the host application.
