The TrueDialog SMS Texting API

More Pre-built Features Than Any Other SMS API. 

Why Build What We’ve Already Built?

Code Less. Move Faster. Save Money.

The features below are not included with Twilio or other SMS API Vendors. All are included free with TrueDialog’s SMS API. We have 47 API endpoints, more than six times our nearest competitor. And our API-first approach offers greater flexibility and makes implementation much smoother.


TrueDialog maintains our own duplicate Opt-Out information in our ISO 9001 cloud-database for extra protection against accidentally texting a contact that has Opted-Out. To achieve this same level of protection on other SMS APIs developers would have to build this capability themselves. This is a significant cost to us, but is greatly valued by our enterprise customers who are serious about compliance.

Our Unique “TrueDialog” Feature

We provide pre-built two-way text dialogs that create threaded, seamless conversations at scale.  No need to build and link all conversations using old “2 way” technology. With our proprietary "TrueDialog" Feature & Contact Center SMS Software, scalable multi-user 2-way texting is pre-built and ready to go.

Mobile App & Call Center Module

Pre-built Android and iPhone mobile app with full administrative controls. Mobilize your call center agents to engage in "TrueDialog" at scale.


Our campaign endpoint lets you send millions of messages with just one API call.  Other providers require one API call for each message sent.  Stop taxing your systems and bandwidth and get faster delivery.

Drill Down Reports

Use our prebuilt reporting or build your own custom reports with our report endpoints. Drill-down into metrics, response rates and analytics on campaigns and also get admin reports for staff and call center agent productivity. Our CDR logs are stored, searchable and retrievable for compliance and to easily research text message history.

Scheduling Engine

Schedule campaigns anytime using our Flex Schedule capabilities. No need to use 3rd party scheduling, ours is built in.


With our full suite of calling APIs, you can easily deploy click-to-call, bridge calls, conference calls, recorded audio, and call forwarding.


Our campaign endpoint lets you send millions of messages with just one API call.  Other providers require one API call for each message sent.  Stop taxing your systems and bandwidth and get faster delivery.

Free Multi-Channel Urgent Alert System

Send instant Mass Notifications and Alerts with SMS Text, Voice, Email, and Social. Urgent Alert System included at no cost to our enterprise customers.
