Build on top
of lınq.
A clean REST API and webhooks for the data that runs your shop — customers, jobs, estimates, invoices and payments. Sync lınq with your accounting stack, your warehouse, or whatever you build next.
Sync customers & jobs
Read and write the customer record and the full job lifecycle — create work from your own intake, push status back.
Invoices & payments
Pull invoice and payment events into your accounting system. Reconcile payouts without copy-paste.
Real-time webhooks
Subscribe to events — job booked, invoice paid, estimate signed — and react the moment they happen.
OAuth 2.0 + scoped API keys.
Authenticate with a workspace API key for server-to-server access, or OAuth 2.0 for apps acting on a customer's behalf. Every token is scoped to the resources it needs.
