> Connect Twilio to sanda: what to prepare, the fields the connection form asks for, and how its data lands in your warehouse.

## Connect Twilio

:::steps
1. **Open the catalogue.** In the console, go to **Data · Connections** and press **New connection**.
2. **Choose Twilio.** It is listed under product and operations; you can also search for it by name.
3. **Fill in the form.** Enter the fields below. Credentials go straight to sanda’s sync engine and are never stored in sanda’s database.
4. **Choose what to sync.** Pick the streams you want, and a sync mode for each. See [choose what to sync](https://docs.sanda-os.com.au/connections/choose-streams).
5. **Run the first sync.** sanda tests the connection, then lands each stream as a table in your warehouse.
