Azure / Entra ID integration
Automatically synchronise the contacts from your Microsoft Entra ID (formerly Azure Active Directory) and send SMS messages to your employees and users in just a few clicks. One central source, always up to date — no more manual imports.
- Free to use
- You only pay SMS credits when you send
- Secure OAuth2 connection
How does it work?
In three simple steps you send SMS messages to your entire organisation.
1. Connect
Securely link your Microsoft environment through an Azure app registration. A one-time setup — we only request read access to your contacts.
2. Synchronise
Your users and their phone numbers are retrieved automatically from Entra ID. Changes in your directory follow along with every synchronisation.
3. Send
Select contacts or groups and send your message — straight from our online tool, to one person or your entire team at once.
