30 * The API kernel dispatches a series of events while processing each API request.
31 * For a successful API request, the sequence is RESOLVE => AUTHORIZE => PREPARE => RESPOND.
32 * If an exception arises in any stage, then the sequence is aborted and the EXCEPTION
33 * event is dispatched.
35 * Event subscribers which are concerned about the order of execution should assign
36 * a weight to their subscription (such as W_EARLY, W_MIDDLE, or W_LATE).
42 * Determine whether the API request is allowed for the current user.
43 * For successful execution, at least one listener must invoke
44 * $event->authorize().
48 const AUTHORIZE
= 'civi.api.authorize';
51 * Determine which API provider executes the given request. For successful
52 * execution, at least one listener must invoke
53 * $event->setProvider($provider).
57 const RESOLVE
= 'civi.api.resolve';
60 * Apply pre-execution logic
64 const PREPARE
= 'civi.api.prepare';
67 * Apply post-execution logic
71 const RESPOND
= 'civi.api.respond';
74 * Handle any exceptions.
