Introducing Box Sign APIs

Today, July 26th, 2021, begins the roll out of Box Sign! Programmatically harness the full functionality of the Box Sign web app experience by leveraging our newest API endpoints to create, list, resend, and cancel Box Sign requests.

Box Sign must be rolled out to your enterprise before use of these endpoints. We will notify Admins as it becomes available for their Box instance. Over the next few months we plan to support Business, Business Plus, Enterprise, Enterprise Suites, and Starter plans. For details on enablement and access restriction, please see our support article.

Creating a Box Sign request

At a minimum, using the create Box Sign request endpoint requires selecting a file for signature, a destination folder for the signed document/signing log, and designating signers. At this time, only one file can be signed per request.

curl -i -X POST "https://api.box.com/2.0/sign_requests" \
     -H "Authorization: Bearer <ACCESS_TOKEN>" \
     -d '{
       "signers": [
          {    
            "role": "signer",
            "email": "example_email@box.com"
          }
        ],
       "source_files": [
          {
            "type": "file",
            "id": "123456789"
          }
       ],
       "parent_folder": 
          {
            "type": "folder",
            "id": "0987654321"
          }
     }'

Fetching a list of all Box Sign requests

The list sign requests endpoint can be used to view a list of all Box Sign requests created by the user associated with the passed Access Token.

curl -i -X GET "https://api.box.com/2.0/sign_requests" \
     -H "Authorization: Bearer <ACCESS_TOKEN>"

For more details, please see our guide and reference documentation.

Fetching a Box Sign request by ID

The get Box Sign request by ID endpoint can be used to view information about a specific Box Sign request. This endpoint requires the sign request’s ID, which can be obtained by using the list Box Sign requests endpoint or in the response when creating a Box Sign request.

curl -i -X GET "https://api.box.com/2.0/sign_requests/<SIGN_REQUEST_ID>" \
     -H "Authorization: Bearer <ACCESS_TOKEN>

For more details, please see our guide and reference documentation.

Resending a Box Sign request

The resend a Box sign request endpoint can be used to resend request emails to any remaining signers.

curl -i -X POST
"https://api.box.com/2.0/sign_requests/<SIGN_REQUEST_ID>/resend" \
     -H "Authorization: Bearer <ACCESS_TOKEN>"

For more details, please see our guide and reference documentation.

Cancelling a Box Sign request

A Box Sign request, that has not yet been signed or declined, can be cancelled using the cancel Box Sign request endpoint. Any outstanding signers will no longer be able to sign the document.

curl -i -X POST
"https://api.box.com/2.0/sign_requests/<SIGN_REQUEST_ID>/cancel" \
     -H "Authorization: Bearer <ACCESS_TOKEN>"

For more details, please see our guide and reference documentation.
