Multiplier

Multiplier (usemultiplier.com) is a global employment platform offering Employer of Record (EOR), Contractor management, and Global Payroll across 150+ countries. Its API surface is integration-oriented - token-authenticated connections used to sync members (employees and contractors), employment contracts, payroll, payments, time off, and invoices between Multiplier and external HRIS systems such as Workday, HiBob, BambooHR, and Personio. Multiplier does not publish an open, self-serve public REST/GraphQL API reference; API access is provisioned per account via Service User tokens. Not to be confused with unrelated companies named "Multiplier".

Multiplier publishes 6 API contracts indexed on the APIs.io network, including Members API, Contracts API, Payroll API, and 3 more. Tagged areas include Employer of Record, Global Employment, Payroll, Human Resources, and Contractors.

Multiplier’s developer surface includes engineering blog, authentication, documentation, and 7 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Employment & Payroll regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
