SMS Tools Walkthrough
There are a couple of options that we provide through our SMS Tools add-on that can help improve your workflow by enabling SMS features. Take a look at the different features we offer to see if this add-on can increase the capability for your workflow.
SMS Tools Add-on
The SMS Tools add-on is an additional charge that provides two SMS-based features that can be included in your workflow: SMS authentication and SMS delivery. This add-on can be used with a Standard API plan or higher. For more details on our API plans, please see our plans and pricing page. For any questions regarding the SMS Tools add-on option or billing, please contact our Sales team with this form.
SMS Authentication
The SMS authentication feature provides the option to include a unique SMS authentication code that is sent to the signer once the signature request is submitted. In order for the signer to open and complete their portion of the document, they’ll need to provide the unique code sent via SMS. This adds an additional layer of security when having your signers complete their signature requests.
SMS Delivery
The SMS delivery feature provides a link to sign the signature request via both email and SMS. Once the signature request is sent to the signers, each signer will receive both an email notification and an SMS message with a link to complete their portion of the document.
