PlanSource
PlanSource is a benefits administration and employee-benefits engagement platform used by employers, brokers, carriers and HR/payroll partners to run enrollment, eligibility, billing and benefits communication. Its public developer surface is the PlanSource Benefits Administration API (Admin API v2), a RESTful HTTPS API of 80 operations across 62 paths covering employee (subscriber) demographics, dependents, beneficiaries, coverages and stacked coverage lines, payroll deductions with lookup codes and pre-tax/post-tax/employer/imputed amounts, Evidence of Insurability decisions and form completions, ACA offer and enrollee reporting data, administrator accounts, and organization portal page content. It is designed to replace fixed-schedule EDI files with near real-time sync between an HCM/payroll system of record and PlanSource. Authentication is OAuth 2.0 client credentials (scope admin_api_v2) or a legacy AuthenticationString + Signature header pair, with OpenID Connect and SAML 2.0 available for end-user single sign-on. The API is documented on a ReadMe developer portal that publishes llms.txt, an agent-skills manifest and an OAuth-gated MCP server, and PlanSource maintains a SafeBase trust center listing SOC 2 Type 2, ISO/IEC 27001:2022, HIPAA, CCPA and 23 NYCRR 500.
PlanSource publishes 13 APIs on the APIs.io network, including ACA API, Administrators API, All API, and 10 more. Tagged areas include Employee Benefits, Benefits Administration, Insurance, Human Resources, and Payroll.
PlanSource’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, authentication, sandbox, and 22 more developer resources.
