How to use bitbucket cloud APIs ?

[abhinav.mr.impractical]

Bitbucket cloud APIs have a good documentation, but I could not find a comprehensive examples showing how to make authenticated calls to those APIs.

My requirement is very simple.  As a bitbucket cloud admin for a given workspace, I would like to get a list of all the repos the workspace has.

I would like to be able to do this from my python backend (a simple script & nothing else). There is no user interaction involved in this case.  Now having gone through the documentation & a bunch of online resources, it appears that there are a few ways to get authentication tokens, which is (obviously) the first step to be able to call any other APIs.

Here are a few things I'm struggling with & would really appreciate any inputs around the same : (PS: pointing me to the right resources would also be great help. Don't necessarily need direct spoon fed answers :) )

1. What's the difference between the different tokens? On Bitbucket cloud I can see App Tokens & Oauth Consumers. Which one is the one to be used in my case above? And with each, what should be the respective header value?
   
   
2. What's the endpoint to which the call needs to be made? For example to get a list of the all repos in the given workspace, for which I am an admin, would it be https://api.bitbucket.org/2.0/repositories/<my_workspace_name_here> or would it be https://bitbucket.org/<my_workspace_name_here>/2.0/repositories/ or would it be something else? 
   
   
3. There is this official python lib from Atlassian https://atlassian-python-api.readthedocs.io/index.html which does seem to talk about how to get the authentication done for Bitbucket cloud using the app password, something like using the below:
   
   

   bitbucket_app_pw = Cloud(
       url='https://api.bitbucket.org/',
       username=bitbucket_username,
       password=bitbucket_app_password,
       cloud=True)

and then the corresponding API call to list the repos seems to be 

bitbucket.project_list()

but the `bitbucket` Cloud object, obtained from the former snippet above, does not seem to have the project_list method at all. Am I missing something here?
