+# Proactive SMS API
+
+The Proactive SMS feature allows you to start personalized two-way conversations using Short Message Service (SMS) messages. These automated interactions are based on campaigns designed in the Ada dashboard, which you can trigger using the Proactive SMS API. With this API, you can use events from external systems to initiate real-time notifications, such as:
+
+* Order updates for e-commerce customers
+* Drip campaigns managed through a marketing automation platform
+* Travel updates such as flight status changes
+* Account notifications or alerts for fintech platforms
+* Alerts to software as a service (SaaS) account holders, such as overage warnings, onboarding reminders, or upsell offers
+
+**Example**
+
+<%= image_tag "images/proactive-sms-api-flow.png" %>
+
+When you send the request to trigger a campaign, you’ll include the phone number of your recipient, along with any metadata that you want to use to personalize your interaction with the chatter. Each piece of metadata becomes a variable that you can use throughout a conversation, by including it in the answers within your campaign.
+
+
+
+## Getting started
+
+To use the Proactive SMS API you need to:
+
+* be an Ada Engage or Ada CX client, with an Ada bot Owner or Administrator account
+* create a new Proactive SMS Campaign (learn how in our [Resource Center](https://adasupporthelp.zendesk.com/hc/en-us/articles/4411541727635-Proactive-SMS-Campaigns))
+* have a SunCo account, and a Twilio account configured with a phone number
+* obtain an API token for authentication
+
+
+
+### Authentication
+
+To connect with the Proactive SMS API, you need an access token that you’ll include in the header of your requests.
+
+1. In the Ada dashboard, go to **Settings > Integrations > API Integrations > Proactive SMS API**.
+2. Click **Configure**.
+3. Copy the API Access Token. Keep it in a safe place, as you won’t be able to access it again.
+
+If you misplace your token, click the **Generate a new Access Token** button to get a new one. When you do this, it invalidates the previous token.
+
+## Proactive SMS API Reference

+You can also copy this address directly from your dashboard, in the **Campaign Triggers** section of your SMS campaign.
+
