How to do API Versioning

1- URL based versioning

Easy and very common way to version api is to include version no in api url.
For e.g. http://myapi/v1.0.0 , http://myapi/v1.0.1

• Easy to use and identify different version by looking URL.
• Over time need to maintain various urls

2- Using query param

Another easy to use startegy for api versioning
For e.g. http://myapi?version=1.0.0

• Same url for different api version
• Need to add tranformation logic to route to particular version

3- Using custom HTTP header

Slight advantage over approach #2 since this will keep url short.

• same url for different api version
• Need to add tranformation logic to route to particular version

4- Using Accept HTTP Header

For e.g. Accept:application/v1.0.0+json , Aceept:application/v1.0.0+json

Slight advantage over approach #3 since no need to add new custom header.

• Same url for different api version
• Need to add tranformation logic to route to particular version
