Why add SMS to your Base44 strategy?
Base44 is an AI app builder that ships full-stack apps with real backends — auth, databases, and server-side functions baked in. Texto plugs in with a single REST API call: paste your API key into a Base44 backend function, POST to https://api.texto.com.au/send, and your app sends SMS to Australian numbers. No SDK, no middleware, no Zapier.
What can you do with Base44 + Texto?
Real use cases for sending SMS from Base44.
User welcome and onboarding SMS
When someone signs up to your Base44 app, fire off a welcome text from the signup function. SMS gets read in 3 minutes — way better than a welcome email that sits unopened.
OTP and verification codes
Generate a 6-digit code in your Base44 backend, store it against the user, and text it through Texto. Cheap, fast 2FA without the cost of dedicated auth providers.
Booking and appointment confirmations
Built a booking app on Base44? Text customers the moment they book, then again 24 hours before. No-show rates drop hard when reminders go via SMS.
Internal alerts to admins
New high-value order, support ticket, or failed payment? Have your Base44 app text the team owner so they hear about it instantly, not on the next email check.
Customer notifications from CRUD apps
Status changed, job complete, invoice ready, whatever — call Texto from the relevant Base44 function and the customer gets a text. One line of code per notification.
