Feature Request: Increase or customize list of categories

[MrCaringi]

It is necessary to increase the quantity of categories listed by the bot,

I suggest two options

• define a new ENVIRONMENT VARIABLE (in docker-compose.yml file) in order to indicate the quantity of categories to be showed
• or maybe paginate the results, using buttons to advance/back the pages

thanks in advance!

Just for the records,

some findings:

Official API documentation regarding the categories endpoint: https://api-docs.firefly-iii.org/#/categories/listCategory

It seems like there is no way to increase the number of items to be returned by the endpoint, is limited to 50, but it support pagination

I propose two solutions:

SOLUTION APPROACH 1:

ask for the firts page, and repeat the request for the URL indicated in the element links.next until there is no more links.next in the API response

SOLUTION APPROACH 2

to get the total page number in the first request (without a page value in the query parameter) meta.pagination.total_pages

this way you can know how many request have to be made in order to get all the categories

Finally, no matter which option is used, I think, in telegram can be implemented pages buttons, i.e (https://t.me/BotFather list of bots)
