My question:

Hello, I have been trying to get a token from a post request:

Post https://auth.mysite.com/oxauth/login

The body includes username and password, when I send this request from the console I can see 4 requests being sent:

Post https://auth.mysite.com/oxauth/login
Get https://auth.mysite.com/oxauth/authorize?scope…
Get https://auth.mysite.com/oxauth/authorize?scope=Email+permission
Get https://auth.mysite.com/#/login-callback/&access_token=9180228c-ef88-43d4-bh83-7fe587542f06

I need to find a way to get that access_token and save it in an environment variable, I’m new in postman and I don’t know how to access a chain response like that one.

I have tried with this one

const responseJson = pm.response.headers.get(‘location’);

console.log(Response URL: ${responseJson});

console.log(pm.request.url.query.toObject())

but both are empty

The OAuth flow is a bit more special since it involves a browser and a callback to Postman. I doubt you can grab the callback parameters from scripts with pm.request.

Do you have any other suggestions that I can take a look?

It would help if you could add more details regarding what you are actually trying to accomplish with Postman and some screenshots showing what you have tried so far.
