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.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/stampli: open an issue to ask a question, or submit a pull request to add artifacts.
