what tool is this yaml for and how is it being used?

[reddev12]

remotely we will execute the ansible script ...and token is created from other script and kept as ansible vars ...just want to place that token variable in this yaml

url will contain f5 rest api

authx variable isn't populating, so that will need to be solved before you can troubleshoot anything else. what does that playbook look like?
