Stampli

Stampli is an AI-driven accounts payable and procure-to-pay automation platform (invoice capture, coding, approvals, vendor management, payments, and corporate cards) that stays aligned to a company's ERP as the system of record. Stampli does NOT publish a public, self-serve developer API or developer portal. What Stampli markets as its "API" is a set of pre-built, in-house cloud-to-cloud ERP integrations (plus on-premises "Bridge" connectors and file-based sync) that Stampli operates on the customer's behalf to sync master data - invoices, vendors, purchase orders, GL accounts, locations/entities, and approvals - between Stampli and 70+ ERPs such as NetSuite, Sage Intacct, QuickBooks, Microsoft Dynamics, SAP, Oracle, and Acumatica. Access is gated behind a sales/onboarding relationship; there is no documented public REST/GraphQL/WebSocket surface, no self-service authentication, no OpenAPI reference, and no published developer documentation as of this catalog entry. Integrations are configured by Stampli during onboarding rather than by third-party developers against an open API.

Stampli is profiled on the APIs.io network. Tagged areas include Accounts Payable, AP Automation, Procure-to-Pay, Invoice Management, and Vendor Management.

Stampli’s developer surface includes documentation, pricing, engineering blog, and 3 more developer resources.
