Base44 SMS Integration

Base44 apps connect directly to the Mobile Message API, with no Zapier subscription or third-party connector required. Base44 is an AI app builder that turns plain-English prompts into working web apps, and its backend functions can call the Mobile Message API to send and receive SMS from any app you build.

Setup takes a few minutes. Add your Mobile Message API key as secrets in your Base44 app, then ask the Base44 AI to create a backend function that sends SMS through our API. Messages are delivered on direct Australian routes at just 1.6c each on your first purchase, using your own business name or a dedicated number as the sender.

Perfect for booking apps, customer portals, and internal tools built with Base44. Send appointment confirmations, order updates, staff alerts, and reminders the moment something happens in your app.

Key features:
• Send SMS from any Base44 app. A backend function calls the Mobile Message API directly, triggered by anything that happens in your app
• Two-way messaging. Inbound replies are forwarded to your app in real time via webhook
• Personalised messages. Fill in names, times, and order details from your app's own data
• Custom sender ID. Send from your business name or a dedicated Australian number
• Built-in opt-out compliance. Add the {optout} placeholder and an opt-out instruction is inserted automatically

A Base44 Builder plan or higher is required, as backend functions are not available on Base44's Free or Starter plans. On the Mobile Message side the integration is free, and you only pay for the messages you send.
