# Linking Twilio as a source - Docs

**Alpha release**

This source is currently in **alpha**. The interface and available tables may change.

Enter your Twilio credentials to pull your Twilio data into the PostHog data warehouse.

## Adding a data source

1.  Go to the [sources tab](https://app.posthog.com/data-management/sources) of the data pipeline section in PostHog.
2.  Click **\+ New source** and then click **Link** next to Twilio.
3.  Find your **Account SID** on the [Twilio Console dashboard](https://console.twilio.com). For the remaining credentials, choose an authentication method:
    -   **API key (SID + secret)** — recommended, since it can be revoked independently. Create a [Standard API key](https://console.twilio.com/us1/account/keys-credentials/api-keys) and copy its `API key SID` and `API key secret`.
    -   **Auth token** — alternatively, use the `Auth token` shown alongside your Account SID in the console.
4.  Back in PostHog, enter your Account SID, pick the authentication method, fill in the matching credentials, and click **Next**.
5.  Select the tables you want to sync, set the sync method and frequency, then click **Import**.

Once the syncs are complete, you can start using Twilio data in PostHog.
