Are you a partner, or a Zentail seller?

Partner integrations

A partner builds one application that many Zentail sellers connect to. You authenticate with the OAuth 2.0 authorization-code grant, and you hold one token per seller per application.

Sales channel

You run a marketplace or storefront, and Zentail sellers want their listings, orders and inventory to flow through it.

Includes three callbacks you implement on your own host for Zentail to call.

Inventory

You hold stock for Zentail sellers and keep quantities in step with their catalog.

Includes a warehouse-status callback Zentail declares but does not yet call.

Third-party logistics

You fulfil Zentail sellers' orders out of your own warehouses.

Covers orders, packages, warehouses and inventory. Shipping runs on the routes the Shipping software reference documents.

Shipping software

You take Zentail sellers' orders, buy the label and report the tracking back.

Includes a warehouse-status callback Zentail declares but does not yet call.

Build on the route each step leads with. Each guide shows a step’s route first and keeps the v1 route beside it in a Legacy (v1) aside. Where only a v1 route exists for a step, that route is the path.

Scripting your own account

A seller scripts their own Zentail account. You generate a token yourself at Settings → API access, and it is minted with a single broad scope.

Seller API

You are a Zentail seller scripting your own account: reports, CSV import validation, vendor lookups and stock.

Uses a token you generate yourself in account settings, not OAuth.
