One system. Every channel. Always up to date.
Synaps maintains a live requirements map for every marketplace. When a platform updates its specs — new mandatory fields, changed taxonomy, stricter image rules — your catalog is automatically re-validated and any new blockers are surfaced and fixed. No manual monitoring. No surprise rejections.
Daily catalog scanning against live marketplace specs
Automatic re-enrichment when requirements change
Validation before submission — not after rejection
