Walls.io Echo

Read and manage the authenticated user's Echo campaigns, their sharing visuals, their folders, and their analytics. All tools operate only on campaigns and folders owned by the connected user. Reference a campaign by its numeric id or slug, a folder or visual by its numeric id. Each campaign holds up to 10 sharing visuals, each with its own box_* element layout and its own sharing_url and sharing_text (empty values inherit from the primary visual at share time); the first visual (lowest position) is the primary one used when the campaign is shared. Add visuals by https URL (preferred) or base64, update their layout and sharing fields, or reorder them. Analytics tools accept an optional from/to date range (YYYY-MM-DD); omitting it returns lifetime totals (summary) or the last 30 days (timeseries/breakdown).
