Dropbox Sign

The Dropbox Sign module is a Drupal integration for the Dropbox Sign electronic signature API.
This module enables seamless integration with the Dropbox Sign API, allowing users to manage and process electronic signature requests directly from Drupal.

This module was inspired by and based on the original HelloSign module, which integrated Drupal with the HelloSign API.
As the HelloSign API evolved into the Dropbox Sign API, this module was adapted to support the new API while retaining the core functionality of the original HelloSign integration.

REQUIREMENTS:

• This module requires the Dropbox Sign PHP SDK.
• This module requires the Encryption module as a dependency.

CONFIGURATION:

Configure Dropbox Sign in Administration » Configuration » System » Dropbox
Sign API or by going directly to /admin/config/system/dropbox-sign:

1. Dropbox Sign API Key:
   The API key associated with your Dropbox Sign account. You can create an
   account at https://app.hellosign.com/account/signUp.
2. Dropbox Sign Client ID:
   The Client ID associated with your Dropbox Sign project. After you have a
   Dropbox Sign account, you can create a client for the domain name you are
   using, and a client ID will be assigned to you.
3. CC email addresses:
   A comma-separated list of email addresses which will be copied on every
   Dropbox Sign signature request. Useful if you want to track completed
   requests by email without manually adding an additional address to every
   signature request.
4. Test mode:
   Enables and disables test mode. In test mode, all requests sent to Dropbox
   Sign will indicate that they are test requests.

USING THE API:

• To create a new Signature Request API connection, fetch the Dropbox Sign service
  and call getSignatureRequestApi().
  $signatureApi = \Drupal::service('dropbox_sign')->getSignatureRequestApi()
• To create a new signature request, call the createSignatureRequest method on
  the Dropbox Sign service with the following parameters:

  $title : Document title
  $subject : Email subject
  $signers : Array of signers with a key of email address and a value of name
  $file : A full path to a local system file
  $mode : The type of signature request, either "embedded" or "email"
  $redirectUrl : The redirected Url after the signature is made (Optional)
  $msg : The email content to be sent for the signature request (Optional)
  
  If success, it returns a signature_request_id token from Dropbox Sign and an
  array of signatures. If failure, it returns an empty array.

• To get the sign_url for the SignatureEmbedRequest, fetch the Dropbox Sign
  service and call getSignUrl().

  $sign_url = \Drupal::service('dropbox_sign')->getSignUrl($signatureId)
  

• To use any of the other methods the Dropbox Sign PHP requires, simply call
  those methods on the signatureApi.
  Ex: $signatureApi->signatureRequestCancel($signature_request_id)
• To include signature place holder inside custom templates, simply add this tag:

  [sig|req|signer1] : represents a placeholder to the signature request of
  the first signer
