API documentation (Enterprise)

Enterprise plan customers have access to the Hammr API, enabling custom integrations with your existing tools and workflows.

The API provides programmatic access to your Hammr data, including contacts, leads, projects, estimates, and invoices. Use it to sync data with your accounting software, build custom reports, or connect to other business tools.

To get started with the API, contact your dedicated account manager. They'll provide your API credentials, documentation, and help you plan your integration.

Common integrations include syncing invoices with QuickBooks, connecting leads from your website contact form, and pulling project data into custom reporting dashboards.

The API follows REST conventions with JSON request and response bodies. Authentication uses API keys passed in the request header.
