We need an API

38.
Consuming the web2000-2008: Desktop browser2008-2012: Mobile browser2008-2012: iPhone and Android apps2010-2014: Tablets, tablets, tablets2014-2016: Your fridge (Internet of Things)

39.
Twitter & FacebookBy show of hands

40.
Make everyone API(as the French say)

41.
What is an API?Software-to-Software interfaceContract between software and developersFunctionalities, constraints (technical / legal) Programming instructions andstandardsOpen services to other software developers (public or private)

42.
Expose services to 3rd partiesValuableFlexibleManagedSupportedHave a plan

43.
Reach More Clients

44.
ASP.NET Web APIPart of ASP.NET MVC 4Framework to build HTTP Services (REST)Solid featuresModern HTTP programming modelContent negotiation (e.g. Xml, json, ...)Query composition (OData query support)Model binding and validation (conversion to .NET objects)RoutesFilters (e.g. Validation, exception handling, ...)And more!

45.
demoBe detailed!Think about RFC 2324 (HTCPCP)

46.
demoASP.NET Web APILet’s craft a quick API

47.
A lot of public API’s…“your API consumer isn’t really your user,but an application acting on behalf of a user”(or: API consumer != user)

48.
So they do this!

49.
In our own API, authN / authZAPI access using OAuth2Access Control Service to the rescue!Client authorized in BrewBuddy.netAccess/refresh tokens through ACS
