About this integration

Connect Docupost to Definable to auto-index uploads, answer questions over a doc set, extract structured fields from contracts. Personas call Docupost's 3 tools directly from chat or scheduled flows. Connect this integration to a knowledge persona — the agent will ground answers in your documents with citations.

Connect Docupost to Definable and it becomes a set of typed tools your agents plan with — triggered by events, run on schedules, or invoked mid-conversation. Every write is checked by the verifier before it lands.

Personas can call any of the 3 Docupost tools directly, then chain the result into another integration without you writing code.

02 How does Docupost authentication work?

Docupost uses API_KEY on Definable. You connect once from the integrations page, scoped to the permissions you choose, and from then on any persona that has the integration enabled can act on your behalf. Tokens are encrypted at rest and rotated automatically.
