If the sender can use SMS Delivery via the DocuSign web app, then an access token for that account member (user) can use SMS Delivery via the eSignature REST API v2.1. Remember to use the API resource limits headers to avoid exceeding your integration key’s hourly limits. But you can use the eSignature REST API to send multiple envelopes that include SMS recipients. The DocuSign web app and the bulk send API methods do not yet support bulk sending with SMS Delivery. For example, with release 1, SMS Delivery can only be used with some types of recipients there’s a limit of five SMS Delivery recipients per envelope and more. Read the SMS Delivery guide to understand the capabilities and limitations of the SMS Delivery feature’s first release.
#Sms plus webapp update
You will need to update your envelopes to use a different authentication technique.
#Sms plus webapp verification
SMS and phone call identity verification methods are not available with SMS Delivery because they are not effective authentication challenges when SMS is used to deliver access to the signing session. For example, turn on Responsive Signing and investigate Smart Sections. Test your envelope formats and templates with mobile devices and update the envelope options to provide the best signing experience for your signers.

With SMS Delivery, the odds are high that the envelope will be signed using a mobile device. If SMS Delivery is not provisioned for your account, contact DocuSign Support for developer accounts or DocuSign Sales for production accounts. Next, use the web app to send an envelope to yourself using SMS Delivery to understand its user experience. If the new Delivery dropdown menu is in the recipient section, then your account has been provisioned with the SMS Delivery feature. Log in to your account using the DocuSign web app. The SMS Delivery User’s Guide is available on DocuSign Support you can also find our API 101 guide and how-to on the Developer Center. Meanwhile, here’s a brief introduction to using SMS Delivery via the eSignature REST API v2.1.


A later release (no schedule yet) will remove the email requirement. In this first release of the SMS Notification feature, the SMS notification messages are in addition to email notifications. Now, with the DocuSign SMS Delivery feature, you can enhance email notifications with real-time SMS notifications sent directly to a signer’s mobile device. Surveys have shown that people now prefer to receive urgent messages via SMS rather than email. Note: For the latest on SMS Delivery, see SMS Delivery Update.
