title: "S3 Connector"
description: "Connect Amazon S3 or S3-compatible storage to sync files into your Supermemory knowledge base"
icon: "aws"
---

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', {
      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.get("SUPERMEMORY_API_KEY"))

    connection = client.connections.create(
        's3',
        access_key_id=os.environ.get("AWS_ACCESS_KEY_ID"),
        secret_access_key=os.environ.get("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 '{
        "accessKeyId": "AKIAIOSFODNN7EXAMPLE",
        "secretAccessKey": "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY",
        "bucket": "my-documents-bucket",
        "region": "us-east-1",
        "containerTags": ["org-123"]
      }'
    ```
  </Tab>
</Tabs>

## Configuration Options

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

## S3-Compatible Services

Use a custom `endpoint` to connect to S3-compatible storage:

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

// DigitalOcean Spaces
endpoint: 'https://nyc3.digitaloceanspaces.com'

// Cloudflare R2
endpoint: 'https://ACCOUNT_ID.r2.cloudflarestorage.com'
```

## Prefix Filtering

Sync only files within a specific path:

```typescript
const connection = await client.connections.create('s3', {
  // ... credentials
  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', {
  // ... credentials
  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 |
