Checklist: Schedule a multi-image carousel without it breaking
Carousels (swipeable multi-image posts) are the most fragile thing to schedule via API. Pre-flight before you queue.
—
Step 1: Confirm the network supports API carousel publishing — IG yes, some others reminder-only.
—
Step 2: Order slides in the upload pane, not the filename — most tools ignore file numbering.
—
Step 3: Match every slide to the same aspect ratio (4:5) or the network crops mid-carousel.
—
Step 4: Keep slides under the cap (IG = 10 for legacy API) or the post silently fails.
—
Step 5: Test one carousel live before batching a week of them.
✔ No reminder pop-ups at posting time
✔ Clean uniform slides
✖ Carousel API support varies wildly by tool
Best for: educational/B2B accounts using swipe-throughs.
Pick this if a carousel ever posted as a single image. Later ($25/mo) and Publer (free) support API carousels.
