Introduction whats is an api

Introduction:Whats is an API?

  • Definition: “language and message format used by an application program to communicate with a control program” .

  • In Simple Terms ,It receives your request, and then, based entirely on the information you gave it returns a result.

  • Ex:Google API's, Flickr API's, Delicious API's etc


Why do companies actually provide api s

Why do companies actually provide API's ?

  • Create an ecosystem of innovation and tap into a wider audience.

  • Once such a freedom is given the applications can be extended in ways that may have been impossible, uneconomical or unimaginable for the original developers to do themselves.

  • The new reality is that open data is a competitive advantage.


Why do we need api s

Why do we need API's?

  • For example:you need to use maps in your application or a project.

  • Highly impossible task for you to launch satellites into space and provide your own map interface.

  • API's come to your rescue. Google Maps or Yahoo Map's API provide rich set of data they have collected and use them for your specific purposes.

  • Over 1000 Web Service API-added to directory of API tracking site programmableweb.com and many more are expected.

  • Big market player’s such as Amazon, eBay, Google and others have already released Web API’s.


Amazon web api s

Amazon Web API's.

  • Amazon Product Advertising API:

  • Opens doors to Amazon's databases-Build Web store to sell Amazon items or your own items.

  • As a Developer you get access to large data that Amazon has like:

    • Reviews, seller reviews,as well as most of the functionality.

    • Retrieving product and pricing information

    • Retrieving customer reviews of a product

    • Retrieving product images

    • Performing simple and advanced searches

    • Retrieving wish lists by name, e-mail, and other identifiers.


How product advertising api works

How Product Advertising API works

  • Your application uses the Product Advertising API to supply details regarding items such as description, images, seller and customer reviews.

  • Customers shop on your web site.

  • Customer is ready to purchase the items in their e-commerce shopping cart.

  • your application sends an form to Product Advertising API and Amazon completes the purchase by getting purchase information.

  • Amazon fulfills the order by shipping the items.


E bay web api s

E-Bay Web API's

  • eBay is a major contender for Amazon in the e-Commerce space, and its database of on-line sales might well be the largest ever assembled.

  • E-Bay Finding API:

    • The Finding API provides programmatic access to the next generation search capabilities on the eBay platform.

    • Lets you search and browse for items listed on eBay, and provides useful metadata to refine searches and enhance the search experience


How the e bay api works

How the E-Bay API works

  • 1) A user enters "laptop" in your cool application.

  • 2) Your app uses makes a search request for " laptop" using one of the eBay Web Services.

  • 3) The eBay database looks for "laptop".

  • 4) The eBay database sends the response back to you using the API.

  • 5) Your app displays the search results to the user.


Comparison of amazon v s ebay web api s

Comparison of Amazon v/s eBay Web API’s

  • Describing Metadata:

    • In comparison to Amazon, eBay’s tagging of Metadata is limited.

    • Amazon as a vendor could pull out more info about the Items dimensions and description.

    • In contrast eBay's only real information is the categorization of the item based on prices and the format used to describe it.

  • Number of Queries made:

    • Amazon doesn’t have any restrictions on the number of queries made except for no more than 1 per sec per IP.

    • Ebay has a limit of 5000 queries per day.

  • REST and SOAP Protocol Support:

    • Both eBay and Amazon e Commerce API’s provide the options of querying the API’s using both REST and SOAP protocols.

    • Though eBay has limited set REST API’s its SOAP and XML API’s are particularly rich.

  • Registration Process:

    • Ebay's has more tedious process,If not confusing.

    • Amazon's is rather friendly and could be completed in breeze.

  • Number of Results returned:

    • Amazon returns 10 items per page for every request.

    • Ebay returns 400 items per page.

    • So eBay's more Item per page is improvement for people looking for more popular items.

  • Documentation:

    • Both Amazon and eBay API’s have been extensively documented and they have lots of tutorials for covering all the details about the API.

    • Very important: In making API easy to use and understand.

  • Developer Community interaction:

    • Amazon has done a good job by supporting their API's well with lot of Developer Forums and organizing Developer Chats.

    • Ebay on the is trying to have similar developer Forums and Help Desk.


Conclusion

Conclusion

  • Amazon is an impressive performer having created a niche set of functionalities for the developers to use and some very useful developer communities.

  • It also doesn’t have any restrictions on the number of queries that can be made unlike the eBay services.

  • eBay-a major player in eCommerce sector and access to its data might well be worth the pain.

  • Ebay has its share of success to with 60k Users.
