TextSpot does not have a public REST API. If that is what brought you here, the honest answer is that we are not the right platform for it, and the last section of this page names the ones that are.
What we have instead is Zapier, which connects TextSpot to roughly 7,000 other apps without anyone writing code. For most businesses that ask about an API, that turns out to be the thing they actually wanted. This page is about telling those two situations apart before you pay anyone.
What an SMS API actually does
An API lets your own software send and receive texts directly. Your system makes a request — this number, this message — and the platform sends it and reports back what happened. Nobody logs into a dashboard, because the software is doing the sending.
That is the whole idea. Texting stops being a thing a person does and becomes a thing your software does, triggered by whatever your software already knows: an order shipped, a balance dropped, a shift opened up, a code needs confirming.
When you genuinely need one
There are real cases. You need an API if any of these describe you:
- You are building texting into a product. Not sending texts as a business, but shipping messaging as a feature your own customers use.
- Your trigger lives in software you wrote. If the event that should fire a text happens inside your own codebase, no off-the-shelf connector knows about it.
- Timing is measured in seconds. Two-factor codes, fraud alerts, dispatch and on-call notifications. Anything where a two-minute delay is a failure.
- You need to act on replies programmatically. Not a keyword autoresponder, but your own logic reading inbound messages and deciding what happens next.
- Your volume makes per-message pricing cheaper than plan pricing. At high enough throughput the maths flips.
When you don’t
Most businesses that ask for an API want automation. Those are different things, and the difference is worth money, because automation is available without hiring a developer.
If the events that should trigger your texts already happen inside tools somebody else built — a CRM, a scheduler, a form, a spreadsheet, a store platform — a connector already exists. Building against an API to get the same outcome is the more expensive route to the same text message.
Signs you are in this group:
- The trigger happens in an app you bought rather than one you wrote.
- You would have to hire someone to use the API you are asking for.
- Your volume is thousands of messages a month, not thousands a minute.
- “API” appeared on a requirements list and nobody can name the workflow it was for.
What we do instead
TextSpot connects to about 7,000 apps through Zapier. You pick a trigger in one app and a TextSpot action follows it. No code, and no developer on retainer to keep it running.
In practice that covers most of what people describe when they say they need an API:
- A booking in Calendly sends a confirmation, then a reminder the day before.
- A new row in Google Sheets texts the person named in it.
- An order marked shipped in your store platform texts the tracking link.
- A deal moving stage in your CRM fires a follow-up.
- A form submission adds someone to a list and sends a welcome message.
Where that approach runs out
Zapier is not a substitute for an API and we would rather say where it stops than let you find out in production.
- Latency. Lower Zapier plans poll on a schedule rather than firing instantly. Fine for a reminder, useless for a login code.
- Throughput. It is built for workflows, not for pushing very large volumes through quickly.
- Branching logic. Simple conditions are fine. Anything resembling a real decision tree gets awkward and fragile.
- Inbound handling. Reacting to replies with your own logic is limited compared with what an API gives you.
- Cost at scale. Zapier bills by task. At high volume those tasks add up and the economics stop making sense.
Hitting any of those walls is a good signal. It usually means you have crossed from wanting automation to genuinely needing an API.
If you need a real API
We would rather tell you now than after you have signed up and discovered it.
SlickText and TextUs both offer a REST API, and both are reasonable choices if that is a hard requirement. Our comparisons cover where each one differs from us on price, setup and what they are built for: TextSpot vs SlickText and TextSpot vs TextUs.
Twilio is worth knowing about but sits in a different category. It sells messaging infrastructure rather than a texting application, so you get an API and a set of building blocks, and you build the product around them. That is the right call if you have engineers and want control over everything. It is the wrong call if you wanted software that already works.
What we are actually good at
Sending texts without building anything. Pricing is published on the site, registration is a one-time $19 and two to three business days, and every plan includes every feature. If that is the shape of the problem, we are a good fit. If you need endpoints and API keys, take one of the links above with our blessing.
