Payactiv Access-as-a-Service API
Access-as-a-Service is Payactiv's API-driven infrastructure for embedding Earned Wage Access, debit and payroll card programs, instant payouts, and HCM workforce-data workflows into a partner platform under the partner's own brand. Payactiv documents the surface as authentication, orchestration, webhooks and sandbox environments, with an OpenAPI-based reference, change log and sandbox samples published inside the developer portal. The specification is not served anonymously.
