The whole platform, end to end.
LongboxSync is a real SaaS — multi-tenant, encrypted, monitored, and shippable to the Shopify App Store. Here's what's inside.
Sources
Whatever you already use, we ingest as-is.
API integration + CBIX import. We respect your existing publisher / variant tags.
Direct CLZ Cloud export support with field mapping.
API source adapter with manual + scheduled refresh.
Drop a .csv, .cbix, or .xlsx in the dashboard and we'll parse the columns automatically.
Destinations
Push to every marketplace your customers shop.
OAuth install, variants + inventory + price sync, real-time order reconciliation.
Sell API + Inventory + Fulfillment. ECDSA-signed notification verification.
Open API v3 with PKCE OAuth, listing publish, receipt webhooks.
Push inventory back into HipComic for cross-promotion.
Sync engine
The invisible work that keeps everything aligned.
Per-item content hash. We only push what actually changed — no surprise rate-limit bills.
Every sync runs in a queued background task with retry + timeout. Bulk jobs survive deploys.
Order webhooks decrement the source within seconds so no marketplace oversells.
Per-tenant cadence from 5 minutes to daily. Pause/resume from the dashboard.
Security & ops
Built like a SaaS, not a script.
Marketplace tokens stored with envelope encryption. We can't read them; you can revoke any time.
Every query is scoped by tenant_id. Audit logs and Sentry events are tagged automatically.
Email + webhook alerts when a sync fails, a credential expires, or a marketplace returns 4xx.
customers/data_request, customers/redact, shop/redact all signed-and-verified out of the box.
