# Integration Settings Discovery

The CLI now has a powerful feature to discover what settings are available for each integration!

## New Command: `integrations:settings`

Get the settings schema, validation rules, and maximum character limits for any integration.

## Usage

```bash
postiz integrations:settings <integration-id>
```

## What It Returns

```json
{
  "output": {
    "maxLength": 280,
    "settings": {
      "properties": {
        "who_can_reply_post": {
          "enum": ["everyone", "following", "mentionedUsers", "subscribers", "verified"],
          "description": "Who can reply to this post"
        },
        "community": {
          "pattern": "^(https://x.com/i/communities/\\d+)?$",
          "description": "X community URL"
        }
      },
      "required": ["who_can_reply_post"]
    }
  }
}
```

## Workflow

```

### 2. Get Settings for Specific Integration

                "required": ["subreddit", "title", "type", "is_flair_required"]
              }

## Use Cases

### 1. Discovery

Find out what settings are available before posting:

```bash
# What settings does YouTube support?
postiz integrations:settings youtube-123

# What settings does Reddit support?
postiz integrations:settings reddit-456
```

### 2. Validation

Check maximum character limits:

```bash
postiz integrations:settings twitter-789 | jq '.output.maxLength'
# Output: 280
```

### 3. AI Agent Integration

AI agents can call this endpoint to:
- Discover available settings dynamically
- Validate settings before posting
- Adapt to platform-specific requirements

```javascript
// Get settings schema
const settings = await execSync(
  `postiz integrations:settings ${integrationId}`,
  { encoding: 'utf-8' }
);
const schema = JSON.parse(settings);

// Check max length
if (content.length > schema.output.maxLength) {
  content = content.substring(0, schema.output.maxLength);
}

// Use required settings
const requiredSettings = schema.output.settings.required || [];
```

### 4. Form Generation

Use the schema to generate UI forms:

```javascript
const settings = await getIntegrationSettings('reddit-123');
const schema = settings.output.settings;

// Generate form fields from schema
schema.properties.subreddit.items.properties.value.properties
// → subreddit (text, minLength: 2)
// → title (text, minLength: 2)
// → type (select: text/link)
// → etc.
```

## Combined Workflow

Complete workflow for posting with correct settings:

```bash
#!/bin/bash
export POSTIZ_API_KEY=your_key

# 1. List integrations
echo "📋 Available integrations:"
postiz integrations:list

# 2. Get settings for Reddit
echo ""
echo "⚙️  Reddit settings:"
SETTINGS=$(postiz integrations:settings reddit-123)
echo $SETTINGS | jq '.output.maxLength'
echo $SETTINGS | jq '.output.settings'

# 3. Create post with correct settings
echo ""
echo "📝 Creating post..."
postiz posts:create \
  -c "My post content" \
  -p reddit \
  --settings '{
    "subreddit": [{
      "value": {
        "subreddit": "programming",
        "title": "Interesting post",
        "type": "text",
        "url": "",
        "is_flair_required": false
      }
    }]
  }' \
  -i "reddit-123"
```

## API Endpoint

The command calls:
```
GET /public/v1/integration-settings/:id
```

Returns:
```typescript
{
  output: {
    maxLength: number;
    settings: ValidationSchema | "No additional settings required";
  }
}
```

## Error Handling

### Integration Not Found

```bash
postiz integrations:settings invalid-id
# ❌ Failed to get integration settings: Integration not found
```

### API Key Not Set

```bash
postiz integrations:settings reddit-123
# ❌ Error: POSTIZ_API_KEY environment variable is required
```

## Tips

1. **Always check settings first** before creating posts with custom settings
2. **Use the schema** to validate your settings object
3. **Check maxLength** to avoid exceeding character limits
4. **For AI agents**: Cache the settings to avoid repeated API calls
5. **Required fields** must be included in your settings object

## Comparison: Before vs After

### Before ❌

```bash
# Had to guess what settings are available
# Had to read documentation or source code
# Didn't know character limits
```

### After ✅

```bash
# Discover settings programmatically
postiz integrations:settings reddit-123

# See exactly what's required and optional
# Know the exact character limits
# Get validation schemas
```

## Summary

✅ **Discover settings for any integration**
✅ **Get character limits**
✅ **See validation schemas**
✅ **Know required vs optional fields**
✅ **Perfect for AI agents**
✅ **No more guesswork!**

**Now you can discover what settings each platform supports!** 🎉
