Ottimate V1 API Capabilities

The Ottimate API lets you integrate with Ottimate’s accounts payable platform. It’s a standard REST API using JSON over HTTPS with proper HTTP methods and status codes.

With the Ottimate API, you can:

  • Manage data - Fetch and update invoices, vendors, and dimensions in Ottimate
  • Build ERP integrations - Sync accounting data from unsupported ERPs to Ottimate

How Ottimate Works

Ottimate Workflow

Ottimate comprises the following main services, each accessible via API:

  • InstantCapture - Extracts invoice data from PDFs and images. Handles complex invoices with hundreds of line items.
  • Core AP - Automates accounts payable processing. Syncs data from your ERP, maps invoices to accounting dimensions, then exports completed bills back to your ERP.
  • VendorPay - Sends payments via ACH, check, or virtual card.
  • Reports - Shows spending patterns, cost breakdowns, and process metrics.

Not all endpoints are currently available. Please see Releases for current availability.
