Quick guide to resolve common connector issues with authentication, syncing, and permissions.

## Quick health check

Check if your connectors are working properly:

<CodeGroup>

```typescript TypeScript
const { connectors } = await supermemory.connectors.list("user-123")

connectors.forEach(connector => {
  console.log(`${connector.provider}: ${connector.account} - last sync ${connector.latestRun?.system.status ?? "never"}`)
})

// Inspect a failing connector's recent runs and the items that failed
const failing = connectors.filter(connector => connector.latestRun?.system.status === "failed")
for (const connector of failing) {
  const detail = await supermemory.connectors.get("user-123", connector.id, {
    include: "syncs",
  })
  console.log(`⚠️ ${connector.provider}: ${detail.latestRun?.error}`)
  console.log(detail.syncs)
}

// Check for stuck documents in the namespace
const { documents } = await supermemory.list("user-123", "documents")
const stuck = documents.filter(doc => doc.system.status === "failed")
if (stuck.length > 0) {
  console.log(`⚠️ ${stuck.length} documents failed to process`)
}
```

```python Python
connectors = client.connectors.list("user-123").connectors

for connector in connectors:
    status = connector.latest_run.system.status if connector.latest_run else "never"
    print(f"{connector.provider}: {connector.account} - last sync {status}")

# Inspect a failing connector's recent runs and the items that failed
failing = [c for c in connectors if c.latest_run and c.latest_run.system.status == "failed"]
for connector in failing:
    detail = client.connectors.get("user-123", connector.id, include=["syncs"])
    print(f"⚠️ {connector.provider}: {detail.latest_run.error}")
    print(detail.syncs)

# Check for stuck documents in the namespace
documents = client.list("user-123", "documents").documents
stuck = [doc for doc in documents if doc.system.status == "failed"]
if stuck:
    print(f"⚠️ {len(stuck)} documents failed to process")
```

```bash cURL
# List connectors in the namespace
curl "https://api.supermemory.ai/ns/user-123/connectors" \
  -H "Authorization: Bearer $SUPERMEMORY_API_KEY"

# Read one connector with its recent sync runs
curl "https://api.supermemory.ai/ns/user-123/connectors/PTzGiUYei7pgzg5buzZHgA?include=syncs" \
  -H "Authorization: Bearer $SUPERMEMORY_API_KEY"

# Check document status in the namespace
curl -X POST "https://api.supermemory.ai/ns/user-123/list/documents" \
  -H "Authorization: Bearer $SUPERMEMORY_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"filter": {"field": "source", "operator": "eq", "value": "notion"}}'
```

</CodeGroup>

<Note>
There is no per-connector document list in v5. `supermemory.list(namespace, "documents")` returns every document in the namespace; read each document's `system.status`.
</Note>

## Common issues

### Connector Missing From List

**Problem:** `connectors.create` returned an `id`, but `connectors.list` and `connectors.get` do not show it

**Solution:** A pending OAuth connector is not visible in list or get until the user finishes authorization. Send the user to `authorization.url` before `authorization.expiresAt`. If the link expired, create the connector again.

### OAuth callback fails

**Problem:** "Invalid redirect URI" error after user grants permissions

**Solution:** Ensure your redirect URL matches EXACTLY what's configured in your OAuth app:

```typescript
// correct - exact match with OAuth app settings
const connector = await supermemory.connectors.create("user-123", {
  provider: "notion",
  redirectUrl: "https://yourapp.com/auth/notion/callback"
})

// Wrong - URL doesn't match
// redirectUrl: "https://yourapp.com/callback"
```

**Prevention:**
- Use HTTPS for production URLs
- Copy the exact URL from your OAuth app settings
- Test the flow in development first

### Documents not syncing

**Problem:** Documents stuck in "queued" or "extracting" status for over 30 minutes

**Solution:** Trigger a manual sync:

```typescript
// Force a sync for the connector
await supermemory.connectors.sync("user-123", "PTzGiUYei7pgzg5buzZHgA")
// 409 means a sync is already running; wait for latestRun.system.status to change
```

If documents consistently fail:
- Read `latestRun.error` and `include: "syncs"` for the failed items
- Check if files are over 50MB (may timeout)
- Verify you have permission to access the documents
- Ensure the document type is supported

### Permission denied errors

**Problem:** Some documents show "permission denied" or aren't syncing

**Solution:** Re-authenticate with proper permissions:

```typescript
// Delete and recreate the connector
await supermemory.connectors.delete("user-123", "PTzGiUYei7pgzg5buzZHgA", {
  deleteDocuments: false,
})

const next = await supermemory.connectors.create("user-123", {
  provider: "google-drive",
  redirectUrl: "https://yourapp.com/callback"
})

// User must re-authenticate
if (next.authorization) window.location.href = next.authorization.url
```

### Sync takes too long

**Problem:** Hundreds of documents taking hours to sync

**Solution:** Set reasonable document limits:

```typescript
const connector = await supermemory.connectors.create("user-123", {
  provider: "onedrive",
  redirectUrl: "https://yourapp.com/callback"
  documentLimit: 500, // Start with fewer documents
})

// Raise it later without reconnecting
await supermemory.connectors.update("user-123", connector.id, {
  documentLimit: 2000,
})
```

## Provider-specific issues

### Google Drive

**Shared Drive Issues**

Shared drives require special permissions. Make sure:
- User has access to the shared drive
- OAuth app has drive.readonly scope
- User is a member of the shared drive

**Picker Not Completed**

With the default scoped sync, syncs may skip the connector until the user finishes the file picker. Read the connector with `include: "picker"` and send the user to `picker.url`.

### Notion

**Database Not Syncing**

Notion databases need explicit permission. If databases aren't syncing:

1. Go to Notion workspace settings
2. Find your integration under "Connections"
3. Click on the integration
4. Select specific pages/databases to share
5. Re-sync after granting access

**Workspace Access**

For full workspace access, a workspace admin must:
1. Approve the integration
2. Grant access to all pages
3. Enable "Read content" permission

### OneDrive

**Business vs Personal Accounts**

Business accounts may have additional restrictions:
- Admin consent might be required
- Some SharePoint sites may be restricted
- Compliance policies may block certain files

### Gmail

**Real-time Sync Not Working**

If emails aren't syncing in real-time but scheduled/manual sync works:

1. Real-time sync uses Google Cloud Pub/Sub webhooks
2. Watch subscriptions expire after 7 days (supermemory auto-renews)
3. Only INBOX label triggers real-time updates
4. Trigger a manual sync to verify the connector is healthy:

```typescript
await supermemory.connectors.sync("user-123", "PTzGiUYei7pgzg5buzZHgA")
```

**Missing Refresh Token**

If Gmail stops syncing after initial setup:

1. The user may have revoked app access in Google Account settings
2. Delete and recreate the connector
3. Ensure user completes full OAuth consent flow

```typescript
// Re-authenticate to get fresh tokens
await supermemory.connectors.delete("user-123", "PTzGiUYei7pgzg5buzZHgA", {
  deleteDocuments: false,
})

const next = await supermemory.connectors.create("user-123", {
  provider: "gmail",
  redirectUrl: "https://yourapp.com/callback"
})
```

**Scale Plan Required Error**

Gmail connector requires Scale Plan or Enterprise Plan. If you see access errors:
- Verify your organization has the required plan
- Contact support to upgrade your plan


## Best practices

1. **Set reasonable document limits** - Start with 500-1000 documents
2. **Use one namespace per user or tenant** - Makes debugging easier
3. **Monitor `latestRun`** - Check weekly for failed syncs
4. **Handle rate limits gracefully** - Implement exponential backoff
5. **Test OAuth in development** - Ensure redirect URLs work before production
