An Overview

Welcome to the FuseSign API

This API Allows you to interact with the FuseSign platform to send out signing bundles.

For more information on FuseSign please see https://fusesign.com or support@fuse.work. We can provide a postman collection upon request

Key Features

  • OAuth2 or fixed header authentication.

  • GUIDs everywhere! (tenants, bundles, documents, customers, webhooks)

  • Webhooks for any events on a sent document bundle.

  • Metadata can be attached to objects to allow reference back to an external API.

  • Multiple methods to achieve the same result. For example:

    • A document can be uploaded before a bundle is sent and linked via ID, or sent via encoded base64, or sent via a download URL.

    • A customer can be created before a bundle is sent and linked via ID or can be included in the bundle payload.

Special Cases

  • Creating a Draft: To create a bundle as a draft, Set the CreationMode to CreateAsDraft.

    • This will populate the DraftUrl on the response bundle which can be used to review and send the bundle.

  • No FuseSign Emails: To disable FuseSign emails Set the Bundle -> Settings -> EmailPreference to NoFuseSignEmails.

    • This will return a CustomerSignUrl for each customer which can be used in your external emails.

  • View Modes (2FA)

    • SmsToSign will require 2FA authentication before signing. [Requires all customers to have a mobile number]

    • SmsToView will require a 2FA code before the recipient can even view the document. [Requires all customers to have a mobile number]

    • EmailToSign and EmailToView only requires an email address.
