Oneflow
Oneflow is a contract lifecycle management and e-signature platform that turns static documents into smart, data-rich digital contracts - covering creation from templates, negotiation, e-signing, and post-sign lifecycle management. The Oneflow Public API is a REST API at https://api.oneflow.com/v1 authenticated with an account API token (x-oneflow-api-token) plus an acting-user email header (x-oneflow-user-email) for permission checks. It lets teams programmatically create contracts from templates, add parties and participants, fill data fields and products, publish contracts for signing, download signed files, and subscribe to contract lifecycle events via webhooks. API access and webhooks are available on the Business and Enterprise plans.
Oneflow publishes 11 APIs on the APIs.io network, including Comments API, Contract Files API, Contracts API, and 8 more. Tagged areas include Contract Management, Contract Lifecycle Management, E-Signature, Digital Contracts, and Document Automation.
Oneflow’s developer surface includes authentication, documentation, and 8 more developer resources.
