Send SMS from the systems you already use.

A ready connection for Altegio, and the API and SMPP for everything else: CRM, online shop, booking system or your own application.

Altegio

Install Messedo in the Altegio marketplace and connect it to your Messedo account: booking confirmations and reminders go out as SMS from your Sender ID.

How to connect Altegio

REST API

JSON over HTTPS with a token: sending, statuses, balance and Sender IDs. Works with any CRM, website or app that can send an HTTP request.

API documentation

Delivery reports to your URL

Messedo sends the final status of every message to your server, repeats it if there was no answer and shows each attempt in the dashboard.

Report format

SMPP 3.4

For SMS platforms and high volumes: plain or TLS connection, up to 10 sessions per account, delivery receipts.

SMPP settings

OTP and notifications

Codes, order statuses and reminders from your system: typical scenarios and the first request.

OTP and transactional SMS

Your system is not listed?

Any system that can make an HTTPS request will do.

Most CRMs and online shop platforms can call an external URL on an event (a webhook). Point it to the Messedo API with your token — or tell us about your system and we will suggest how to connect it.
