# Integrations

> Connect external systems once, then use them from any pipeline. Pipelines call providers through a proxy; secrets never touch generated step code.

A **provider** is an external system the platform can call—Gmail, Slack, Snowflake, and so on. An **integration** is your authenticated connection to one provider. Connect a provider once; reuse it across pipelines, apps, and queries.

## Provider catalog

| Provider     | Category     | Auth                 | Tutorial                                       |
| ------------ | ------------ | -------------------- | ---------------------------------------------- |
| Gmail        | Email        | OAuth (Nango)        | [Connect Gmail](/docs/integrations/gmail)           |
| Slack        | Messaging    | OAuth (Nango)        | [Connect Slack](/docs/integrations/slack)           |

| Pappers      | Public data  | API key              | [Connect Pappers](/docs/integrations/pappers)       |

## Connection statuses

Once connected, each integration shows one of three statuses:

| Status           | Meaning                                                                                                                                                                  |
| ---------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **Connected**    | Auth is valid; pipelines using this provider will run.                                                                                                                   |
| **Disconnected** | The connection was deleted or never completed.                                                                                                                           |
| **Error**        | The provider rejected a recent request (revoked permissions, expired credential, scope missing). Look at **Monitoring → Priority actions** for the **Reconnect** prompt. |

## How pipelines reach the provider

Generated step code never sees raw credentials. The pipeline calls a platform proxy that injects the right token (Nango handles OAuth refresh; the platform handles API keys) and routes the request. This is why:

* You connect once, not per pipeline.
* Revoking a connection takes effect everywhere immediately.
* Rotating a credential doesn't require touching any step.

See [Authentication](/docs/integrations/authentication) for the auth modes used by each provider type.
