I have created a Python module to interact with Bitbucket. This module consists of all the curl commands in official Bitbucket REST API for Data Center instances.
On that module, I built an application capable of transferring all the, projects, users, groups with repositories; as it is in the source Bitbucket instance. This project is open-source and publicly available on Github.
Can I share this Python module in official pages and my project in Atlassian Marketplace (with Java version)? Are there any legal issue?
