How I Built a Simple, Pay-As-You-Go SMS API for Developers

#sms #api #saas

Hi Devs! 👋

Like many of you, I’ve worked on projects that needed SMS functionality—whether it was for alerts, reminders, or notifications. But every time, I found existing SMS APIs either too expensive, overly complicated, or locked behind subscription models that didn’t make sense for small projects or MVPs.

So, I decided to build something simpler: SMS Textr.

Why I Built SMS Textr
I wanted to create an SMS API that is:

Affordable: Pay only for what you use, no monthly subscriptions.
Simple to integrate: Get started in minutes with minimal setup.
Built for developers: Straightforward API documentation and example code to help you hit the ground running.

How It Works

Step 1: Sign up and grab your API key.
Step 2: Send a POST request with the recipient number, message, and API key.
Step 3: Done! Your SMS is on its way.
Here’s an example in Node.js:

// Node.js code to send SMS using our API
const axios = require('axios');

axios.post('https://smstextr.web.app/api/sendsms', {
            to: '+1 123-456-7890',
            message: 'Hello from SMS Textr API!',
            apikey: 'Your_API_Key'
})
.then(response => console.log(response.data))
.catch(error => console.error('Error:', error.response.data));

Who Is It For?
Developers: Testing or adding SMS to their projects.
Small businesses: Sending appointment reminders or customer updates.
Startups: Cost-effective messaging during early MVP stages.
