Trello API get json from board, Power Ups And automations

I’m trying to download the json that Trello itself makes available because I have some power ups that are not listed in the REST API.
My idea is to download the json automatically, but I can only perform this procedure on public boards.

My idea is to download the json link and place it in a cloud bucket to process and consume in a dw.

Does anyone have any ideas on how I can perform this procedure?

Thanks.

Not quite sure if this is what you are asking, but I think you are trying to access a board JSON, like this on ANY board, not just public boards:

https://trello.com/b/QyOJuXQO.json

You will need to create a standard API project get an API key, sign-in using the standard authentication flow (https://developer.atlassian.com/cloud/trello/guides/rest-api/authorization/), get your token and then from there, you can use a function like this one to grab the board data:

  getWholeBoardData = async (shortLink, name, key, token) => {
    // NOTE: There is an issue here if the board has a "/" in the name.
    //       So we have to parse it out so that we can access the data properly.
    if (name.indexOf("/") > 0 || name.indexOf("\\")) {
      name = name.replace(/\\/g, " - ").replace(/\//g, "-");
    }
    /** @type {String} */
    const uri = `https://trello.com/b/${shortLink}/${name}.json?key=${key}&token=${token}`;
    /** @type {Response} */
    const response = await fetch(uri, { method: 'get' });
    /** @type {JSON} */
    const json = await response.json();
    if (json !== undefined && json !== null && json !== "") {
      return json;
    } else {
      return null;
    }
  }

But it requires the service you are using to be authorized as a user and a member of that board.
