Hi @Arun1,

Here is how you request access token via Postman for Atlassian 3LO:

  1. Enter the API URL to which you want to make a call. For ex:

  2. Click on the ‘Authorization’ tab and select ‘OAuth 2.0’.

  3. Then click the ‘Get New Access Token’ button. You should see a dialog box. Fill them as shown below.

  4. Make sure the above callback URL is updated in your app settings page too in

  5. When you click the ‘Request Token’, you will be directed to login screen and then will receive the access token with other data like refresh token, expiry etc.

Let us know if you have any more questions :slight_smile:

Oh ok. Basic auth for REST APIs might fit your bill. It uses a username and API token. Please keep in mind this is only useful for making calls from scripts.


Hi @aagrawal2 ,
I have followed the same flow but I am not redirected to the login page,
for me its showing this error Please see the image and guide me what I should do to resolve this.

Hey @AbhishekJaswal, my name is Dmitrii, I’m a developer on DAC.
It looks from the error that you were not logged in on
Could you please login there and try the OAuth2 flow again?
