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.
