Send KakaoTalk and SMS from your app
Register the message on the server, then pass a name and a few values from the app. Phone numbers never travel through the browser.
KakaoTalk business messaging is not offered by Lovable (feature comparison, 2026-07-26). Channel setup, sender-number registration, and template review are still filed by the business owner — we cannot do those for you.
What it is
A booking that nobody notices is the expensive kind. A message on arrival is the cheapest fix for it.
Who receives the message, what it says, and which sender number it uses are all server-side. The app passes a registered template name and a bounded set of values, so reading the front-end code reveals no phone numbers.
Message bodies are sealed with a key derived per project, and they are removed with the project when it is deleted.
A KakaoTalk message can fall back to SMS, and a send can be scheduled up to 30 days ahead.
How to use it
Step 1. Store the SOLAPI keys
The API key and secret go into the project vault. They are read immediately before a send and never reach the app source.
Step 2. Register what may be sent
Body text, sender number, KakaoTalk channel and template identifiers, allowed variables, and buttons are declared on the server. Nothing outside that declaration can be sent.
Step 3. Send by name
The app passes the template name, values, an optional scheduled time, and an idempotency key. Delivery status is available through a status lookup.
What we measured
Measured on 2026-07-21 against the code and database boundary. No message has been sent through a live SOLAPI account yet.
What it does not do
One recipient: the project owner
Messages go to the verified mobile number of the project owner. Sending to each of your customers is not built yet.
Kakao review is yours to file
Business channel creation, sender-number registration, and template approval are filed under your business registration. That track sits with the account owner.
Marketing messages are out of scope
Consent capture, advertising labels, and night-time sending limits for marketing messages are not in the product.
Alimtalk and short SMS only
Friend-talk and long-form SMS are not wired.
