Example code showing integrating of Nexmo and MailChimp. Shows acting on a MailChimp list via SMS, as well as using MailChimp list fields to broadcast SMS to a group.

The subscribe.php script checks incoming SMS messages for an email address and subscribes those addresses to a MailChimp list. The sender's number is stored in MailChimp as well.

The broadcast.php script fetches a MailChimp list, and sends a pre-defined SMS when a phone number is found in the configured field.

Configuration can be set in config.ini or as environment variables, with environment variables taking precedence.
