Help with Lemmy API

I would like to be able to use the command line (curl) to get a list of communities I am currently subscribed to.

I know that there is a full-blown API, but it only briefly covers what it is possible with simple a curl request, and most of it seems to refer to an API that runs in javascript (which seems excessively complex for what I want to do?)

A simple curl request like this seems to work,

curl "https://mander.xyz/api/v3/community/list" | jq

But I wouldn't know how to make it list only communities that I subscribe to? Does anyone know more?

For subscribed communities you have to add an auth parameter (that you can obtain by POST'ing {username_or_email: "your_name", password: "your_password"} to /user/login, then extracting the jwt from the response) and type_=Subscribed. A complete request would look like that:

curl "https://mander.xyz/api/v3/community/list?auth=verylongstring&type_=Subscribed" | jq
- While this is the correct syntax, in reality the API is broken and isn't returning communities (either filtered or sorted first) by their listingtype == "Subscribed"
- Rofl I don't know why someone downvoted you, this was nice information thanks.
  
  I like to add that the keys must be wrapped in double quotes to be parsed as proper JSON.
  
  # POST to login endpoint curl -v --data '{"username_or_email": "username", "password": "password"}' --header 'Content-Type: application/json' https://example.com/api/v3/user/login
  
  You are totally right, seems like I forgot them ^^'
- What if the account has 2FA?
  
  In that case add a totp_2fa_token field to the login struct which holds the top token. The rest remains the same.
- This works! Thanks.
  
  If you're up for it, one last question: just running curl "https://mander.xyz/api/v3/community/list?auth=longstring&type_=Subscribed gives me only a few subscribed communities.
  
  I can increase the number of subscribed communities that I get back, by adding &limit=.
  
  curl "https://mander.xyz/api/v3/community/list?auth=longstring&type_=Subscribed&limit=50"
  
  However, putting the limit too low I don't get all my subscribed communities, while putting the limit too high results in an error.
  
  Is there a way to set limit to "max" or the limit to "nil" or something like that?
  
  Wait, I see, the fetch limit is 50...
  
  Any ideas how I could easily get all communities I subscribed to?
