[poojarathod]

Hi Sir, I have a question: If I want to use the token that I received after logging into an application as a variable in the header of all subsequent requests, can it be done? I tried using the same syntax of using a global variable in the body "{{var_name}}", in he header section, but getting an error. Could you pls let me know how I can do this?

[Swapnil-npiw]

good evening sir, 1)please take one project(BANKING DOMAIN/TELECOM) tell how to do in that.
2nd question is that how to do simple API testing without internet in postman with one example.

[anudeepreddy]

Thank you, mr pavan for this session😊🙏

[chaitanyasunkara]

Thank You, Pavan Ji. Your Sessions are helping me. Small Correction in this session Instead of pm. global.set, we need to use collection variable - Thanks

[dhananjaymalhotra]

Hi Sir. Thanks for the videos. In API chaining, since the variable is set at collection level, we will have to use pm.collectionVariables.set("username", value); instead of pm.globals.set("username", value); to get the desired output.

[venkatjayakumar]

Awesome Mr Pawan. Excellent detailed explanation.

[santanunayak]

Sir if I have to learn rest assured with java and I want to know everything about API automation, should I watch all your postman videos or only starting 4?

[sohelahmadkhan]

all your videos based on postman are amazing, Thanks for these videos
it is really very helpful for the freshers and for the experienced as well.

[sivakrishna-qpyr]

It is very useful sir.. thanks for sharing your knowledge to us

[sivakrishna]

Where did you handling error? suppose, first request is failed due to some issue and response 4XX. then why are you are not stopping to execute update request?

[kshipra]

2 Questions--1) the variable you created for API chaining is Collection variable or Environment/Global Variable ???? 2) At 17:47, it is not clearly understood how is this created variable substituted in subsequent request.

[sachiniyer]

00:00 API chaining
18:00 Authorization
