Connect Amazon S3 buckets or S3-compatible storage services (MinIO, DigitalOcean Spaces, Cloudflare R2, Tigris) to sync files into your Supermemory knowledge base.

<Note>
The S3 connector requires a **Scale Plan** or higher. You can also create S3 connectors directly from the [Supermemory Console](https://console.supermemory.ai).

## Quick setup

<Tabs>
  <Tab title="TypeScript">
    ```typescript
    import { Supermemory } from "supermemory"

    const supermemory = new Supermemory({ apiKey: process.env.SUPERMEMORY_API_KEY })

    const connector = await supermemory.connectors.create("org-123", {
      provider: "s3",
      config: {
        bucket: "my-documents-bucket",
        region: "us-east-1",
        accessKeyId: process.env.AWS_ACCESS_KEY_ID!,
        secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY!,
      },
    })

    // S3 doesn't require OAuth; authorization is null and the first sync starts now
    console.log("Connector ID:", connector.id)
    ```
  </Tab>
  <Tab title="Python">
    ```python
    from supermemory import Supermemory
    import os

    client = Supermemory(api_key=os.environ["SUPERMEMORY_API_KEY"])

    connector = client.connectors.create(
        "org-123",
        request={
            "provider": "s3",
            "config": {
                "bucket": "my-documents-bucket",
                "region": "us-east-1",
                "accessKeyId": os.environ["AWS_ACCESS_KEY_ID"],
                "secretAccessKey": os.environ["AWS_SECRET_ACCESS_KEY"],
            },
        },
    )

    # S3 doesn't require OAuth; authorization is None and the first sync starts now
    print(f"Connector ID: {connector.id}")
    ```
  </Tab>
  <Tab title="cURL">
    ```bash
    curl -X POST "https://api.supermemory.ai/ns/org-123/connectors" \
      -H "Authorization: Bearer $SUPERMEMORY_API_KEY" \
      -H "Content-Type: application/json" \
      -d '{
        "provider": "s3",

          "region": "us-east-1",
          "accessKeyId": "AKIAIOSFODNN7EXAMPLE",
          "secretAccessKey": "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY"
        }
      }'

    # Response: {"id": "PTzGiUYei7pgzg5buzZHgA", "authorization": null}
    ```
  </Tab>
</Tabs>

## Configuration options

For S3, provider-specific fields go inside the `config` object. The namespace is in the URL, and `documentLimit` stays top-level in the body.

| Parameter | Location | Required | Description |
|-----------|----------|----------|-------------|
| `bucket` | `config.bucket` | Yes | S3 bucket name |
| `region` | `config.region` | Yes | AWS region (e.g., `us-east-1`). Use `auto` for S3-compatible providers that don't expose AWS-style regions (MinIO, R2, Tigris). |
| `accessKeyId` | `config.accessKeyId` | Yes | AWS access key ID or S3-compatible service key |
| `secretAccessKey` | `config.secretAccessKey` | Yes | AWS secret access key |
| `endpoint` | `config.endpoint` | No | Custom endpoint for S3-compatible services |
| `prefix` | `config.prefix` | No | Key prefix filter (e.g., `documents/`) |
| `documentLimit` | top-level | No | Maximum documents to sync (default: 10,000) |

<Note>
Credentials are stored encrypted and are never returned by `connectors.get` or `connectors.list`. The `config` in responses contains only non-secret fields such as `bucket`, `region`, `endpoint` and `prefix`.
</Note>

## S3-compatible services

Use `config.endpoint` to connect to S3-compatible storage. These services don't use AWS-style regions, so set `config.region` to `auto`. The value is still required for request signing but the service ignores it.

```typescript
// MinIO
const connector = await supermemory.connectors.create("minio-sync", {
  provider: "s3",
  config: {
    bucket: "my-bucket",
    region: "auto",
    accessKeyId: "minio-key",
    secretAccessKey: "minio-secret",
    endpoint: "https://minio.example.com",
  },
})
```

Common S3-compatible endpoint values:

| Service | `config.endpoint` | `config.region` |
|---------|-------------------|-----------------|
| DigitalOcean Spaces | `https://nyc3.digitaloceanspaces.com` | `nyc3` |
| Cloudflare R2 | `https://<account-id>.r2.cloudflarestorage.com` | `auto` |
| Tigris | `https://t3.storage.dev` | `auto` |

Cloudflare R2 example:

```typescript
const connector = await supermemory.connectors.create("r2-sync", {
  provider: "s3",
  config: {
    bucket: "my-bucket",
    region: "auto",
    accessKeyId: process.env.R2_ACCESS_KEY_ID!,
    secretAccessKey: process.env.R2_SECRET_ACCESS_KEY!,
    endpoint: "https://<account-id>.r2.cloudflarestorage.com",
  },
})
```

<Note>
For S3-compatible services, `config.endpoint` is the base S3 endpoint. Do not include the bucket name in the endpoint URL; pass the bucket separately as `config.bucket`.
</Note>

## Prefix filtering

Sync only files within a specific path:

```typescript
const connector = await supermemory.connectors.create("engineering-docs", {
  provider: "s3",
  config: {
    bucket: "company-data",
    region: "us-east-1",
    accessKeyId: process.env.AWS_ACCESS_KEY_ID!,
    secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY!,
    prefix: "documents/engineering/", // Only syncs files under this path
  },
})
```

## Multi-Tenant Buckets

A connector syncs into exactly one namespace. For a bucket shared by many tenants, create one connector per tenant namespace and point each at that tenant's path with `config.prefix`:

```typescript
await supermemory.connectors.create("user-123", {
  provider: "s3",
  config: {
    bucket: "user-files",
    region: "us-east-1",
    accessKeyId: process.env.AWS_ACCESS_KEY_ID!,
    secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY!,
    prefix: "users/user-123/",
  },
})
```

## Connector Management

### Check Sync Status

<Tabs>
  <Tab title="TypeScript">
    ```typescript
    const connector = await supermemory.connectors.get("org-123", "PTzGiUYei7pgzg5buzZHgA", {
      include: "syncs",
    })

    console.log("Bucket:", connector.config?.bucket)
    console.log("Last sync:", connector.latestRun?.system.status, connector.latestRun?.error)
    console.log("Files synced:", connector.documentCount)
    ```
  </Tab>
  <Tab title="cURL">
    ```bash
    curl "https://api.supermemory.ai/ns/org-123/connectors/PTzGiUYei7pgzg5buzZHgA?include=syncs" \
      -H "Authorization: Bearer $SUPERMEMORY_API_KEY"
    ```
  </Tab>
</Tabs>

### Delete Connector

<Tabs>
  <Tab title="TypeScript">
    ```typescript
    await supermemory.connectors.delete("org-123", "PTzGiUYei7pgzg5buzZHgA")
    ```
  </Tab>
  <Tab title="cURL">
    ```bash
    curl -X DELETE "https://api.supermemory.ai/ns/org-123/connectors/PTzGiUYei7pgzg5buzZHgA" \
      -H "Authorization: Bearer $SUPERMEMORY_API_KEY"
    ```
  </Tab>
</Tabs>

<Warning>
By default, deleting a connector removes all synced documents from Supermemory. To keep documents, pass `deleteDocuments: false` (`DELETE /ns/{namespace}/connectors/{id}?deleteDocuments=false`).
</Warning>

### Manual sync

The call returns `409` while a sync for that connector is already running.

<Tabs>
  <Tab title="TypeScript">
    ```typescript
    await supermemory.connectors.sync("org-123", "PTzGiUYei7pgzg5buzZHgA")
    ```
  </Tab>
  <Tab title="cURL">
    ```bash
    curl -X POST "https://api.supermemory.ai/ns/org-123/connectors/PTzGiUYei7pgzg5buzZHgA/sync" \
      -H "Authorization: Bearer $SUPERMEMORY_API_KEY"

    # Response: {"id": "PTzGiUYei7pgzg5buzZHgA", "status": "queued"}
    ```
  </Tab>
</Tabs>

## Sync behavior

| Feature | Behavior |
|---------|----------|
| **Initial sync** | Fetches all files matching prefix filter |
| **Incremental sync** | Only files modified since last sync |
| **Sync schedule** | Every 4 hours + manual triggers |
| **Document limit** | 10,000 files per connector (default) |

## IAM permissions

Minimum required permissions:

```json
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": ["s3:GetObject", "s3:ListBucket"],
      "Resource": [
        "arn:aws:s3:::your-bucket-name",
        "arn:aws:s3:::your-bucket-name/*"
      ]
    }
  ]
}
```

## Error codes

| Code | Message | Solution |
|------|---------|----------|
| 401 | Authentication failed | Verify access key and secret |
| 403 | Access denied | Check IAM permissions and bucket policy |
| 404 | Bucket not found | Verify bucket name and region |
