API testing deals with verifying and validating the business logic of 
an application, which is typically encompassed in the business layer 
and is instrumental in handling all the transactions between the user 
interface and underlying data. Additionally, it also deals 
with contract testing i.e. verifying the compatibility and interactions 
between various services.  
 
The contract is between a client/consumer and an API/service 
provider.  
 
Testing APIs is a task not to be taken lightly since they can span 
multiple applications and are also used for third party integrations. 
Our article here identifies the top 5 common mistakes that people 
tend to commit while testing APIs.

Testing API in isolation 
 
API automation without considering interacting modules/plugins, data 
input/output, and the environment is a big folly that can lead to a potential 
disaster. APIs often depend on other APIs and sometimes on external services 
also.  
 
It is vital to test the third-party APIs in a test environment and then test the 
dependent API along with those APIs to have a holistic picture. In a nutshell, the 
whole ecosystem needs to be tested in order to ensure that any changes/upgrades 
in other APIs do not impact the functioning of dependent APIs. Ideally, the 
whole workflow should be checked multiple times with a variety of inputs to 
cover all possibilities.

Ignoring regression testing 
 
Not performing regression testing enough on APIs can prove to be the single 
biggest failure point.  
APIs keep evolving as and when the functional requirements evolve and change. 
Any minor change should be tested thoroughly.  
It is wrong to assume that minor changes will not have a major impact on the 
functioning of the API and other dependent modules/API.
