This is not our API. This repository is an independent, third-party profile of a company's publicly available API surface, maintained by API Evangelist. API Evangelist does not operate, host, resell, or support this company's APIs, and is not affiliated with or endorsed by the company unless stated on the profile.
Where the information came from. Everything here is assembled from material a member of the public can reach with a browser and no credentials — the company's own website, developer portal and documentation, the specifications it publishes for public use (OpenAPI, AsyncAPI, JSON Schema,
apis.json,llms.txtand similar), its public repositories, and its public status, pricing and changelog pages. Nothing here is obtained by breaching a system, defeating an access control, or using credentials of any kind.The rating is an independent assessment. The Kin Score and Agent Readiness rating are independently calculated scores of a company's public API artifacts, produced by API Evangelist against a published rubric. They are not certifications, endorsements, security assessments, or audits, and they score published artifacts — not the quality, safety, or security of the software.
Corrections, re-scores, and removal are free. No partnership, contract, or purchase is required, and you do not need to justify the request.
- Something wrong? Open an issue on this repository, or email info@apievangelist.com.
- Published something new? Ask for a re-score and we will re-run the rating.
- Want the listing taken down? Say so and we will honor it. The profile is reduced to your company name, a factual description, and a link to your own site, and the company is recorded as unrated — never scored zero for having asked.
Response times. Acknowledgement within one business day; removal or restriction within two business days; corrections and re-scores within five business days.
On a security or compliance team? Email info@apievangelist.com with security in the subject line and you will get a person, not a form. We will tell you exactly which public URLs this profile was built from so your team can see the same surface we did, and we will take the listing down on request while you work through it.
Full detail: Where this data comes from
Stampli is an AI-driven accounts payable (AP) and procure-to-pay automation platform. It automates invoice capture and coding, approval workflows, vendor management, payments, and corporate cards, while staying aligned to a customer's ERP as the system of record.
APIs.json: https://raw.githubusercontent.com/api-evangelist/stampli/refs/heads/main/apis.yml
Stampli does not offer a public, self-serve developer API. This catalog entry is an honest, sourced stub documenting that fact.
What Stampli refers to as its "API" is not a developer-facing product. It is a set of pre-built, in-house integrations that Stampli builds, operates, and maintains itself:
- API integration (cloud-to-cloud): Managed connectors that auto-sync master data between Stampli and cloud ERPs such as NetSuite, Sage Intacct, and QuickBooks Online.
- Bridge integration (cloud-to-on-premises): An executable application that moves data between on-premises ERP applications (e.g., SAP S/4HANA, Sage 100) and Stampli.
- File integration: Templated file-based sync for ERPs where no API or Bridge connector exists.
Stampli explicitly states its integrations are "built in-house" by its own engineering team rather than relying on third-party connectors or developers. There is:
- No developer portal.
developer.stampli.comdoes not resolve. - No published API reference, OpenAPI/Swagger document, or endpoint list on Stampli's own properties.
- No self-service authentication, API keys, or sandbox documented publicly.
- No documented webhooks, REST, GraphQL, or WebSocket surface available to third parties.
Access to any programmatic data flow is gated behind a sales and onboarding relationship; Stampli configures the ERP sync on the customer's behalf. Third-party API tracker sites list speculative "OpenAPI/webhook/auth" capability flags for Stampli, but none are corroborated by a public Stampli developer resource, so they are not treated as confirmed here.
Even though there is no public API, Stampli's managed integrations move a well-understood set of AP/procure-to-pay objects between the ERP and Stampli. These are documented here as modeled, not confirmed endpoints, because Stampli exposes no public reference for them:
- Invoices (capture, coding, custom fields)
- Vendors / vendor master data
- Purchase Orders (2- and 3-way matching, line items)
- GL Accounts and coding/dimension fields
- Locations / Entities (master lists)
- Approvals / approval workflows
- Payments and corporate cards
- Accounts Payable
- AP Automation
- Procure-to-Pay
- Invoice Management
- Vendor Management
- ERP Integration
- FinTech
- No Public API
- Gated API

Stampli does not publish list pricing. Cost is quote-based and varies by invoice volume, number of users, and modules selected; buyers must contact Stampli sales for a quote. Implementation/onboarding is a separate cost. See https://www.stampli.com/pricing/.
