How do I fetch more than 1000 actions?

[Deleted user]

I'm developing a Trello application where it grabs JSON files and converts it to CSV, and from what I see, even SAVING a file from a link like https://trello.com/b/ID.json manually and automatically only saves the first 1000 actions, and the board I want to archive as JSON has more than 1000 actions, I've also asked Stack Overflow and haven't found much of an answer (posts over there said that 1000 was the limit).

@[deleted]  The API rate limits will prevent you from getting more. See https://help.trello.com/article/838-api-rate-limits

To overcome it I would put a trigger on any change on that board and or any specific set of actions and sent to an endpoint that process the json into a file. From there you can do your magic. 
Just curious, what application are you trying to build? In this demo, a custom power up gathers data and sends it a endpoint Superhero Power and a module is automatically executed. https://youtu.be/hR_dnGGsHNw

I'm simply trying to archive a board, and I figured it out in the meantime, I just sent multiple requests and used the &before parameter and changed what would go into the &before parameter every time, so I'd get new actions.
