This page is about WebAPI session methods, in a series for the WebAPI reference manual.

startSession

Start a Web AIM session. Since the AIM server needs to deliver asynchronous events, such as receiving IMs or buddy updates, a session is required for some of the APIs. However most of the APIs do not require a session, so there is no need to create one. After starting a session the AIM Session Id (aimsid) can be used instead of an NINA Authentication Token for most of the APIs. An NINA Authentication Token is required to start a session, which can be obtained with either getToken or clientLogin.

If end user interaction is required, a redirect URL is provide that needs to be shown to the end user in a DHTML control (such as an iframe). This redirection is to request the user's permission to access their Buddy List.

If an iframe is used, the calling code can detect when the end user has completed the interaction by looking for the #CONSENTDONE URL fragment, which the iframe will add to the parent document. The startSession call must be repeated at this point. If the end user does not give permission, the iframe will add the URL fragment #CONSENTCANCEL.

When using a token created with clientLogin the startSession call must be signed. An example of how to calculate sig_sha256 can be found at ClientLogin Example. URL signing requires the computers clock to be accurate or the use of hostTime returned by clientLogin, parameters must be in alphabetical order, and percent-encoding uses upper case characters.

fetchEvents

Fetch outstanding events for an aimsid, waiting up to timeout milliseconds before returning. This URL is never formed on its own - instead, the URL is created by taking the fetchBaseURL returned by startSession or the last fetchEvents call, appending the required format parameter, and then optionally appending a requestId or callback parameters.

Appending the aimsid is not necessary; the API automatically adds it to the fetchBaseURL as the first parameter. The client should wait at least timeToNextFetch milliseconds between calls and make sure to use the new fetchBaseURL returned for the next call. Using an old fetchBaseURL will cause previous events to be repeated. A session will be timed out if there isn't an active fetchEvents for more then 30 seconds.

Input Parameters

Type	Field	Description
Format	f	[Required] The format of the data returned

Integer	timeout	[Default 1 hour] Timeout in milliseconds that the server will wait before returning. Minimum 500ms, maximum 1 hour. On timeout the server will still respond, there will be no events however. For a web application this must be set.
Boolean	peek	If true, then this fetch will not update the most recent seqNum returned

endSession

To be used when the user logs out or navigates away from the application, endSession ends an Web AIM session and set this session offline. A sessionEnded event will be generated after the last event is retrieved, so the client knows when to stop fetching events. If there isn't a active fetchEvents for more then 30 seconds, the backend will auto end the session.

startOSCARSession

Start a OSCAR AIM session. This API requires that the token came from a previous clientLogin call and that the URL is signed. For a complete example on using startOSCARSession see the OSCAR Protocol Signon Example. URL signing requires the computers clock to be accurate or the use of hostTime returned by clientLogin, parameters must be in alphabetical order, and percent-encoding uses upper case characters.

The lang is the 2 letter language code for I18N (default: en) and the locale is the 2 letter Locale code for I18N (default: us). If not passed in, the language will be extracted from HTTP header (Accept-Language) and if that is not available will default to "en-us".
