How do I authenticate?

With a per-tenant API key sent as a Bearer token. Generate keys (with scopes) in app.zobrx.com → Settings → Developers; the secret is shown once at creation.

Which modules are available?

Two are live: multi-channel Ecommerce — unified orders, returns, settlements, reimbursements and commission tax invoices across Amazon, Flipkart, Meesho, Myntra, Snapdeal, JioMart, AJIO, Shopify and offline, plus inbound product/stock sync from your ERP — and Amazon Vendor Central (purchase orders, inventory sync, invoices). Per-endpoint scopes gate each key, and the same API extends to more Zobrx modules over time.

Can Zobrx push data to my ERP?

Yes. Pull POs on a schedule, or register a webhook endpoint and Zobrx posts each new or changed PO, HMAC-signed, with retries. Invoices can flow back via API push, file upload, or a feed Zobrx polls.

Are there rate limits and idempotency?

Per-key rate limits return 429 with Retry-After. Every write accepts an Idempotency-Key header so retries never duplicate.

Is the API versioned?

Yes — the base path is /api/v1. Changes within a major version are additive; breaking changes ship under a new version.

Do you have SDKs or a sandbox?

The API is plain REST/JSON and works with any HTTP client today; official SDKs are on the roadmap. Contact us for sandbox or test-account access.

v1 · Preview

One API between Amazon and your ERP.

Connect your own ERP — Tally, SAP, Busy or custom — directly to the marketplace workflows Zobrx automates. Pull purchase orders, sync inventory, push invoices. Same auth, permissions and audit trail as the dashboard.

How it works

A bidirectional loop with your back office

Zobrx sits between Amazon Vendor Central and your ERP, so procure-to-pay runs without anyone re-keying data.

Purchase orders → your ERP

Zobrx ingests POs from Amazon Vendor Central. Pull them on a schedule, or register a webhook and Zobrx pushes each new PO to your ERP, HMAC-signed.

Inventory → auto-acknowledge

Sync stock levels back to Zobrx. It accepts the fulfillable quantity per PO line and backorders the rest — automatically, or as a suggestion you confirm.

Invoices → Amazon

Generate invoices in your ERP and push them to Zobrx. It maps each to the right PO, validates the GST/HSN tax split, and submits to Vendor Central.

Your ERP can act as a client (pull POs, push invoices) or a server (receive PO webhooks, expose an invoice feed Zobrx polls).

Quickstart

One key. Plain REST.

The Zobrx API is JSON over HTTPS. Authenticate with a per-tenant API key, target a connected Vendor Central account with one header, and call any endpoint with the HTTP client you already use.

API-key auth

A per-tenant key sent as a Bearer token. Generate and revoke keys in Settings → Developers; the secret is shown once.

Idempotency

Every write accepts an Idempotency-Key header, so retries never create duplicates.

Predictable limits

Per-key rate limits return 429 with Retry-After, so backoff is straightforward.

Ecommerce module

Every channel, one unified shape

Read your orders, returns, settlements, reimbursements and tax invoices across Amazon, Flipkart, Meesho, Myntra and more — or push your ERP catalog and stock into Zobrx. All money is in paise; buyer PII is redacted unless the key holds the ecommerce:pii:read scope.

GET/v1/ecommerce/orders

Unified order lines across Amazon, Flipkart, Meesho, Myntra, Snapdeal, JioMart, AJIO, Shopify and offline. Filter by channel, store, date, state.

GET/v1/ecommerce/returns

Multi-channel returns with claim-eligibility deadlines and reimbursement tracking.

GET/v1/ecommerce/settlements

Per-cycle settlement summaries — gross, fees, tax withheld, net settled, variance. Plus line-level detail.

GET/v1/ecommerce/reimbursements

Amazon FBA reimbursements bucketed by reason (warehouse-lost, damaged, fulfilment-error…).

GET/v1/ecommerce/tax/commission-invoices

Marketplace commission GST invoices with IGST/CGST/SGST splits, per channel and total.

GET/v1/ecommerce/inventory/products

Zobrx's unified per-product inventory rollup across channels and warehouses.

POST/v1/ecommerce/inventory/products

Inbound: push your ERP catalog + stock into Zobrx. Idempotent per SKU; a scheduled pull-feed is also supported.

Reads flow Zobrx → your ERP; products/stock flow your ERP → Zobrx (push, or a feed Zobrx polls on a schedule).

Webhooks

Push, not just poll.

Register an ERP endpoint and Zobrx posts each new or changed purchase order the moment it arrives from Amazon — so your back office reacts in real time instead of polling.
