API testing can be one of the most challenging parts of software and QA testing because APIs can be complicated, they are often based on protocols and standards that we often do no encounter in other kinds of testing. While developers tend to test only the basic functionality they are working on, testers are in charge of testing functionality, performance and security of APIs, discovering how all components work together from end to end.

APIs are what gives value to an application. It’s what makes our phones “smart”, and it’s what streamlines business processes. If an API doesn’t work efficiently and effectively, it will never be adopted, regardless if it is a free or not. Also, if an API breaks because errors weren’t detected, there is the threat of not only breaking a single application, but an entire chain of business processes hinged to it

Our API Testing Services

Types of API’s we Test

REST

REST stands for REpresentational State Transfer which is new on the block as compared to SOAP which means it must overcome all the problems with SOAP. REST is a lightweight protocol which uses URL for all the needed information. It uses four HTTP methods to perform task-
  • Get- To get the information. For example getting longitude and latitude in case of location mapping API.
  • Post- To insert some data in resource.
  • Put- To update the resource.
  • Delete- To delete from resource.

SOAP

SOAP API- Stands for Simple Object Access Protocol. It uses XML for message exchanging. All the information which is required to perform this task is given in its WSDL which is Web Service Description Language. SOAP is heavy weight due to its extensive used standards and XML. The main advantages of SOAP over Rest is that it has built in error handling and it can be used with other protocols like SMTP
