trello.uploadAttachment sends file bytes to a card as multipart/form-data and can use the attachment as the card cover.

automations/upload-trello-attachment.automation.ts

import { automation, onDashboardRun } from "automate.ax"
import { trello } from "automate.ax/trello"

export default automation("Upload Trello attachment", () => {
  onDashboardRun({ title: "Upload Trello attachment" })
  trello.uploadAttachment({
    card: "card-id",
    file: new File(["Release notes"], "release-notes.txt", {
      type: "text/plain",
    }),
    name: "Release notes",
    setCover: false,
  })
})

Provide card as an ID, short link, or URL and file as a File. Optional name sets a display name of at most 256 characters. setCover defaults to false. Optional second argument { account } selects a Trello binding. Returns Signal<TrelloAttachment> with the uploaded attachment’s metadata. Trello applies its provider upload-size and board limits.
