What does getData(callback) retrieve for a custom block?

Explanation:
getData(callback) is used to retrieve the custom block’s saved configuration and pass it to the provided callback so the Journey Builder editor can restore the block to its existing state. This lets the editor pre-fill fields with the values the user previously saved, ensuring continuity when the block is reopened or edited. It’s about loading and rehydrating state, not about authenticating the user, updating the canvas in real time, or setting the entire block content directly. Authentication is handled separately, and canvas updates or rendering are managed by other lifecycle methods.
