Hello Team,
I am using Rational team concert v6.0.6 from opensource jazz.net and using the opensource Bitbucket provided by atlassian.
I am trying to configure RTC to use the Bitbucket repository (RTC can integrate with Github)
I am configuring the Bitbucket repository in RTC and from that i am using the webhook url

When i am configuring the Webhook in Bitbucket, i am not having a option to add the authentication details of RTC, I used App password for the same. but didn't work.
for any trigger event in Bitbucket, i am getting the below error.

Can anyone please let me know that the integration with RTC is possible or not?. and if yes then can you please route to the relevant documentation or please let me know the steps.
Reference details:
RTC Version: 6.0.6
BitBucket Cloud is used from https://bitbucket.org
Thanks for the help!
Abhilash
