Campaign Subscription Management

Messaging activities fall under the regulatory guidelines of several groups, depending on the nation in which you send the messages. For more information see Preapproved US Short Codes compliance requirements

You use the opt-in API to:

Create an opt-out process so a user can unsubscribe to your campaign
Resubscribe a user to you campaign

Listen to the incoming requests and manage your recipient mailing list accordingly.
Send a request.
Check the response.

Unsubscribe to your campaign

Unsubscribe requests for Event Based Alerts are forwarded to the webhook endpoint you set in Dashboard.

To handle unsubscribe requests:

Listen to the incoming unsubscribe requests and manage your recipient mailing list accordingly. Once a recipient number has unsubscribed from your campaign, any outbound SMS to that number will be blocked.
Send a request and see the list of phone numbers that are unsubscribed from your campaign:

var https = require('https');

   'Content-Length': Buffer.byteLength(data)
