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.

True Team-to-1 Dialog

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.

Database Sync

We maintain a copy of your SMS texting data in our ISO 9001 cloud-database.  Records Retention is set to 5 years to help keep you CTIA complaint. Our CDR logs are searchable and retrievable if you need to research message history. All included free as a part of our SMS API and our full platform solution.

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.

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.

How does TrueDialog SMS stack-up to the competition? 

Unlike API-only competitors, TrueDialog offers both a complete turn-key Enterprise SMS Texting Platform as well as the TrueDialog SMS API. As a result, our SMS API customers have seamless access to all of our pre-built features; a clear advantage to our API-only competitors. So developers,  if you want to save money, code less and move faster, see how we compare.
