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

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

## Quick Setup

<Tabs>
  <Tab title="TypeScript">
    ```typescript
    import Supermemory from 'supermemory';

    const client = new Supermemory({
      apiKey: process.env.SUPERMEMORY_API_KEY!
    });

    const connection = await client.connections.create('s3', {
      metadata: {
        accessKeyId: process.env.AWS_ACCESS_KEY_ID!,
        secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY!,
        bucket: 'my-documents-bucket',
        region: 'us-east-1'
      },
      containerTags: ['org-123']
    });
    ```
  </Tab>
  <Tab title="Python">
    ```python
    from supermemory import Supermemory
    import os

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

    connection = client.connections.create(
        's3',
        metadata={
            'accessKeyId': os.environ["AWS_ACCESS_KEY_ID"],
            'secretAccessKey': os.environ["AWS_SECRET_ACCESS_KEY"],
            'bucket': 'my-documents-bucket',
            'region': 'us-east-1'
        },
        container_tags=['org-123', 's3-sync']
    )
    ```
  </Tab>
  <Tab title="cURL">
    ```bash
    curl -X POST "https://api.supermemory.ai/v3/connections/s3" \
      -H "Authorization: Bearer $SUPERMEMORY_API_KEY" \
      -H "Content-Type: application/json" \
      -d '{
        "metadata": {
          "accessKeyId": "AKIAIOSFODNN7EXAMPLE",
          "secretAccessKey": "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY",
          "bucket": "my-documents-bucket",
          "region": "us-east-1"
        },
        "containerTags": ["org-123"]
      }'
    ```
  </Tab>
</Tabs>

## Configuration Options

For S3, provider-specific connection fields are passed inside the top-level `metadata` object. General connection options stay top-level.

| Parameter | Location | Required | Description |
|-----------|----------|----------|-------------|
| `accessKeyId` | `metadata.accessKeyId` | Yes | AWS access key ID or S3-compatible service key |
| `secretAccessKey` | `metadata.secretAccessKey` | Yes | AWS secret access key |
| `bucket` | `metadata.bucket` | Yes | S3 bucket name |
| `region` | `metadata.region` | Yes | AWS region (e.g., `us-east-1`). Use `auto` for Cloudflare R2. |
| `endpoint` | `metadata.endpoint` | No | Custom endpoint for S3-compatible services |
| `prefix` | `metadata.prefix` | No | Key prefix filter (e.g., `documents/`) |
| `containerTagRegex` | `metadata.containerTagRegex` | No | Regex to extract container tags from file paths |
| `containerTags` | top-level | No | Tags for organizing connections |
| `documentLimit` | top-level | No | Maximum documents to sync (default: 10,000) |

<Note>
In the Python SDK, use `container_tags` for the top-level option, but keep S3 metadata keys in camelCase: `accessKeyId`, `secretAccessKey`, and `containerTagRegex`.
</Note>

## S3-Compatible Services

Use `metadata.endpoint` to connect to S3-compatible storage:

```typescript
// MinIO
const connection = await client.connections.create('s3', {
  metadata: {
    accessKeyId: 'minio-key',
    secretAccessKey: 'minio-secret',
    bucket: 'my-bucket',
    region: 'us-east-1',
    endpoint: 'https://minio.example.com'
  },
  containerTags: ['minio-sync']
});
```

Common S3-compatible endpoint values:

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

Cloudflare R2 example:

```typescript
const connection = await client.connections.create('s3', {
  metadata: {
    accessKeyId: process.env.R2_ACCESS_KEY_ID!,
    secretAccessKey: process.env.R2_SECRET_ACCESS_KEY!,
    bucket: 'my-bucket',
    region: 'auto',
    endpoint: 'https://<account-id>.r2.cloudflarestorage.com'
  },
  containerTags: ['r2-sync']
});
```

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

## Prefix Filtering

Sync only files within a specific path:

```typescript
const connection = await client.connections.create('s3', {
  metadata: {
    accessKeyId: process.env.AWS_ACCESS_KEY_ID!,
    secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY!,
    bucket: 'company-data',
    region: 'us-east-1',
    prefix: 'documents/engineering/' // Only syncs files under this path
  },
  containerTags: ['engineering-docs']
});
```

## Dynamic Container Tags

Extract container tags from S3 key paths for multi-tenant setups:

```typescript
const connection = await client.connections.create('s3', {
  metadata: {
    accessKeyId: process.env.AWS_ACCESS_KEY_ID!,
    secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY!,
    bucket: 'user-files',
    region: 'us-east-1',
    containerTagRegex: 'users/(?<userId>[^/]+)/'
  },
  containerTags: ['user-files']
});

// File: users/user-123/documents/notes.md → container tag: user-123
// File: users/user-456/reports/q4.pdf → container tag: user-456
```

<Warning>
The regex must contain a named capture group `(?<userId>...)` and be less than 200 characters.
</Warning>

## Connection Management

### Delete Connection

<Tabs>
  <Tab title="TypeScript">
    ```typescript
    await client.connections.deleteByID('conn_s3_abc123');
    ```
  </Tab>
  <Tab title="cURL">
    ```bash
    curl -X DELETE "https://api.supermemory.ai/v3/connections/conn_s3_abc123" \
      -H "Authorization: Bearer $SUPERMEMORY_API_KEY"
    ```
  </Tab>
</Tabs>

<Warning>
By default, deleting a connection removes all synced documents from Supermemory. To keep documents, pass `deleteDocuments=false` as a query parameter: `DELETE /v3/connections/:id?deleteDocuments=false`
</Warning>

### Manual Sync

<Tabs>
  <Tab title="TypeScript">
    ```typescript
    await client.connections.import('s3', {
      containerTags: ['org-123']
    });
    ```
  </Tab>
  <Tab title="cURL">
    ```bash
    curl -X POST "https://api.supermemory.ai/v3/connections/s3/import" \
      -H "Authorization: Bearer $SUPERMEMORY_API_KEY" \
      -H "Content-Type: application/json" \
      -d '{"containerTags": ["org-123"]}'
    ```
  </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 connection (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 |
