For more information on FuseSign please see [https://fusesign.com](https://fusesign.com/) or <developersupport@fuse.work>. \
\
\&#xNAN;*To interact with API using postman, we suggest following the process of importing* [*swagger into postman*](https://learning.postman.com/docs/getting-started/importing-and-exporting/importing-from-swagger/) *using the public* [*swagger.json*](https://api.fuse.work/swagger/v1/swagger.json)

### 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.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://fuseworks.gitbook.io/fusesign/getting-started/readme.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
