ConnextDeveloper API
A full REST API for messaging
Send SMS, voice, and email, manage subscribers, and read logs programmatically — everything the portal does, over a clean REST API.
Org-messaging tools rarely give you an API
Most communication tools built for schools, clinics, and congregations lock you into their dashboard. When you want to trigger messages from your own app or sync your contacts, there's no way in.
- No programmatic way to send from your own systems
- Contact lists that can't sync automatically
- Delivery data trapped in a dashboard
- Waiting on support to provision access
Everything the portal does, programmatically
One REST API at api.connext.ms/api/v1 for messaging and data.
Send across channels
Trigger SMS, voice, and email from your own applications with the same capabilities the portal offers.
Manage subscribers
Create, update, and organize contacts and groups through the API to keep your systems in sync.
Read logs & analytics
Pull per-recipient delivery status, error categories, and click counts to power your own reporting.
Uncommon for org-messaging tools
A genuine full REST API is rare among tools built for schools, camps, and clinics. Connext gives you named, self-service API keys so you can build without waiting on anyone.
Questions, answered
Does Connext have an API?
Yes. Connext offers a full REST API at api.connext.ms/api/v1 that does everything the portal does — send messages, manage subscribers, and read logs — with self-service API keys.
What can I do with the messaging API?
You can send SMS, voice, and email, create and update subscribers and groups, and pull delivery logs and click analytics, all programmatically from your own applications.
How do I get API keys?
API keys are self-service. You create named keys yourself in the portal, so there's no need to wait on support to start building.
