Common errors

Could not download media — the mediaUrl is unreachable or returns wrong content-type. Confirm the file is served as image/webp.
Sticker too large — stickers must be ≤ 100 KB. Compress before uploading to your CDN.
Customer has not messaged within last 24 hours — outside the customer service window. Stickers can't be sent as templates, so wait for a new inbound first.
