Integrations let your workflows talk to external platforms. Some nodes require a
connected integration before they can be used — you connect these on the
**Integrations** page in the app, and the corresponding nodes then appear in the
Node Library.

A node that needs an integration shows an **Integration required** note on its
reference page and links back to the relevant guide below.

## Managing integrations

The **Integrations** page lists the integrations you have connected. To add one, click
**Add Integration** and pick it from the dialog. Integrations you can connect only once,
such as Ytel or ElevenLabs, show **Connected** there when they already are.

The **Status** column shows one of two values:

- **Active** — the credentials are saved.
- **Needs Attention** — the provider rejected the saved credentials. This applies to Ytel
  and Zendesk. Open the integration and replace them.

Click the edit button on a row to open it. Tandem never shows a saved secret again, so a
saved API key, token, or password appears as **Saved**, with the last four characters where
Tandem keeps them. Type in the field to replace it. Leave it blank to keep the saved value.
Credentials that work as a pair, such as an AWS access key ID and secret access key, must be
entered together. Slack's optional signing secret also offers **Remove**.
