Description:
Currently, the legacy Bitbucket Cloud invitation endpoint (POST https://api.bitbucket.org/1.0/invitations/\{accountname}/{repo_slug}{}) is one of the few v1 resources still supported for repository-level invitations. However, it does not support Atlassian API Tokens for authentication.

Customers attempting to use modern API Tokens receive authentication failures, as these legacy endpoints currently only support older methods like App Passwords.

Suggested Change:
Update the authentication layer for the /1.0/invitations endpoint to support Atlassian API Tokens, providing a consistent experience with the v2 REST APIs.

Workaround:
For now, users can be invited using app passwords (if you have any) or directly from the UI
