To use the library, you need to know how to get some values. Also, some values will be described here, it is not necessary to know them, I decided to explain them for general understanding
key / token
DO NOT SHARE IT
The token is needed for authorization and operation of requests from your account. There are 3 ways to get a token:
if you look at the responce of character.get_histories(), then you will see that each story has its own external_id
topic_external_id / topic
The ID of the feed, I don't know where it comes from and how to get it. Also, community feed have their topic_external_id, you can get them in post.get_topics()
tgt / username
It is also a character identifier. It would be more correct to call it the nickname of the character
creator_id
Your account ID. Needed for functions with chat2, stored in your account information
