How can I get all Actions for a Board using Trello's Rest API? - rest

Question

I want to get all the actions for a board, but Trello limits the results to 1000. I understand the correct way to deal with this is to paginate. I've tried both before and page as keywords:
Basic Call:
https://api.trello.com/1/board/[boardID]/
?key=[key]&token=[token]
&actions=commentCard&actions_limit=1000
Alternatives:
Before:
https://api.trello.com/1/board/[boardID]/
?key=[key]&token=[token]
&actions=commentCard&actions_limit=1000&
before=[oldest_returned_action's_date]
Page:
https://api.trello.com/1/board/[boardID]/
?key=[key]&token=[token]
&actions=commentCard&actions_limit=1000&
page=[page_number]
The result never varies --- I always get back [limit] number of actions, and they're always the same no matter the call. I checked the dates in what was returned and they certainly don't respect the before parameter. I even tried lowering the limit to make sure I wasn't trying to return more than I possessed. The problem persists.
How can I correctly get all actions for a Trello board?

Answer 1

Actions are in reverse chronological order (newest-to-oldest), so to page through the actions on a board, you would use something like:
curl "https://api.trello.com/1/boards/${BOARD_ID}/actions/?key=${TRELLO_API_KEY}&token=${TRELLO_TOKEN}&limit=1000"
then, from the last element of the array returned by the the above, select the date or id and pass that as the before parameter in the next call, e.g.:
curl "https://api.trello.com/1/boards/${BOARD_ID}/actions/?key=${TRELLO_API_KEY}&token=${TRELLO_TOKEN}&limit=1000&before=${DATE_OR_ID_OF_LAST_ACTION}"
and repeat, passing in either the id or date of the last action as the subsequent before parameter.
