What Is an SMS API?
An SMS API (Application Programming Interface) allows businesses to send and receive text messages programmatically through their chosen software or apps. API integration puts more control in your hands for your marketing targets, enabling high-volume messaging for reminders, marketing, alerts, and secure authentication.
The Trum·pia Advantage
Contact Management
With Trum·pia's SMS API, you have powerful database management at your fingertips. You don't have to write code to create lists, add contacts, update them, or even unsubscribe them. It's almost like having a built-in CRM database at no additional cost. We even handle compliance requirements such as disclosures, opt-out footers, and blocking messages for subscribers who texted “Stop.”
End User Tools
Trum·pia is more than just an API. We also offer a cloud service that includes a suite of powerful user tools like automated workflows and Smart Targeting that save you lengthy programming and code maintenance time. Do less work, yet become more productive than ever.
2-Factor Authentication
Quickly increase login security with our 2-factor authentication. This secures your software or website by requiring a one-time passcode that's either emailed or texted to subscribers.
Number Options
Trum·pia's API service supports dedicated shortcode, 10DLC, and toll-free options. Enjoy high volume throughput, reliability, and scalability. In particular, our short code and toll-free numbers can handle up to 300 and 150 messages per second, respectively.
Compliance
Be compliant. Use high throughput numbers to
mass message rather than rotating P2P numbers.
Accolades
Named Best for Marketing Campaigns by Forbes Advisor







Every Channel
Short Codes
Get a dedicated 5- or 6-digit number that is provisioned for mass text messaging, and you can both send and receive SMS and MMS at the number. Messages sent from short codes benefit from faster message delivery, higher open rates, and more, making them ideal for SMS marketing.
Toll-Free Numbers
Use a 10-digit toll-free number to send and receive messages. Toll-free numbers give the same benefits as dedicated short codes without the higher cost.
10-Digit Long Code (10DLC)
Use a compliant 10-digit local number to send and receive messages. 10DLC numbers give the same benefits as dedicated short codes without the expense and lengthy approval process.
Landline Texting
Send and receive text messages through your existing business landline number. This allows you to publish a single familiar number for customers to text and call without having to share your personal number.
MMS
Send more than just a plain 160-character message. With MMS support, you can send pictures and videos as well as 500-character messages for more engaging content. Multimedia messaging allows your messages to stand out from the crowd.

Frequently Asked Questions
Is SMS API secure for sensitive data?
What is Toll-Free API?
A Toll-Free API is an API that uses a Toll-Free number to send messages instead of a short code. These are 10-digit numbers that begin with the prefix 800, 888, 877, 866, 855, 844, or 833, and they give you the appearance of a large, nationally known company. Wireless carriers allow these numbers to send text messages for commercial use.
What are the advantages of a Toll-Free API?
One of the best things about using a Toll-Free number is that there is very minimal setup time. The process to choose and switch your Toll-Free number should be completed in minutes. For example, Trum·pia’s provisioning process is instant and should not require any downtime for your texting campaigns.
With a Toll-Free API, you can send SMS text messages and make calls from the same number, so your customers don’t have to worry about reaching you via a different number. The same phone number can be used for voice calls, faxes, and texts, which establishes a consistent, familiar channel for communicating.
If I don't have a coding team, can I still use an API?
Absolutely. If you don’t have a coding team, you can either hire Trum·pia to build integrations for you or use our Zapier integrations to recreate many of the same functions. Our customer support provides additional tech help for clients as they need it.
