Native integrations and a REST API.

These integrations connect Mercantyl to the ERP, accounting, CRM, payments, and shipping tools you already run. They handle data movement between systems.

They are not how you get B2B features. Per-buyer pricing, NET terms, MOQs, multi-user accounts, quote-to-order, and PO workflows are part of the core platform. No app store, no per-feature subscriptions on top of yours. See the B2B toolkit

50+ native integrations, plus REST and webhooks for everything else.

REST API & webhooks

Every entity in Mercantyl, products, prices, orders, buyers, fulfillments, is available via authenticated REST. Subscribe to webhook events to drive your own pipelines.

  • Bulk import/export endpoints (CSV and JSON)
  • Real-time order webhooks (created, paid, shipped, returned)
  • Inventory sync automation across warehouses
  • Rate-limited at 10K req/min on Professional+
  • OAuth 2.0 + scoped API keys
  • OpenAPI 3.1 spec for your codegen pipeline

Built for ERP, OMS, and DIY stacks

Enterprise ERP

NetSuite and Salesforce ship pre-wired. Inventory, customers, and orders sync bidirectionally. Field-level mapping is configurable.

Accounting & Tax

QuickBooks online sync. TaxJar and Avalara integrations for sales-tax compliance. Push invoices and payments automatically.

Marketing & CRM

Klaviyo for buyer-segment campaigns. Slack for ops alerts. Zapier for the long tail of business apps you already use.

Custom workflows

Webhook + API combo handles anything else. Most integrations take a single afternoon, no vendor SOWs.
