Build it your way
If your system can make an HTTPS request, it can text your customers. Create an API key in the portal, post a number and a message, and KiwiTxt handles delivery, the inbox and the record keeping.
- In every plan
- 14-day free trial
- Nothing to install
Send a text with one HTTPS request, and have replies posted back to your own system.
One request to send
POST a mobile number and a message with your key as a bearer token. That is the whole integration.
Safe to retry
Send an idempotency key and a repeated request returns the original result instead of texting again.
Replies pushed to you
Point KiwiTxt at your endpoint and inbound texts are delivered there, signed and retried if you are down.
No code needed either
Prefer not to build? A custom webhook or the Zapier app does the same job without writing any.
API and webhooks questions
Where do I get an API key?
A workspace admin creates one in the portal under Tools, and can revoke it at any time.
Are there rate limits?
Yes, a per-workspace ceiling so one runaway loop cannot flood your customers or your bill.
Is the API included?
Yes, in the one plan, with the texts charged as usual.
