Connect StartERP to everything you use
Your sales, stock, customers and accounts are yours. Send them to the tools you already run, and let those tools write back, without waiting for us.
Four ways in
REST API with OAuth2
A client per program, read or change per area, IP allow-list, rate limits, a request log and a sandbox store. OpenAPI description and a Postman collection; no fee per call.
Signed webhooks
Sales, returns, quotations, purchases, customers, vendors, products and expenses are posted to your address the moment they are saved, signed with HMAC-SHA256 and retried when your side is down.
Zapier and Make
Start a Zap or a Make scenario on a new sale or customer, and add customers and sales from other apps: Google Sheets, Shopify, HubSpot, Slack and thousands more, with no code.
MCP server for AI apps
Connect Claude, ChatGPT, Cursor and other AI apps to your store with a personal key. They read what you may read, and any change waits for your approval.
Up and running in minutes
- Add the API access add-on to your store.

See it in the demo store
The demo shows the API clients and the developer guide. In your own store, webhooks and the API work the moment they are made.
