Signaturely
Signaturely is simple electronic signature software for sending, signing, and managing legally binding documents online. Beyond the web app, Signaturely offers a documented public REST API (base https://api.signaturely.com/api/v1) gated behind separately billed API plans (Gold, Platinum, Titanium). The API is authenticated with an API key ("Authorization: Api-Key {API_KEY}") issued from the account API settings, with OAuth, embedded signing, and embedded requesting available on higher tiers. It lets developers send signature requests from templates, bulk-send from CSV data, manage documents (list, download, share, send reminders, revert, activity), manage templates and folders, manage team members, and subscribe to webhooks for document events. There is no separate "contacts" resource; signers are supplied inline on each signature request.
Signaturely publishes 7 APIs on the APIs.io network, including Documents API, Folders API, Signature Requests API, and 4 more. Tagged areas include Electronic Signature, E-Signature, Document Signing, E-Signature API, and Contracts.
Signaturely’s developer surface includes authentication, documentation, engineering blog, and 9 more developer resources.
