This enables integration with third-party APIs, custom backend services, and external data sources without modifying the core application code. + +## Table of Contents + +1. [Basic Concepts](#basic-concepts) +2. [Configuration](#configuration) +3. [Usage Examples](#usage-examples) +4. [Field Sources](#field-sources) +5. [Best Practices](#best-practices) +6. [Troubleshooting](#troubleshooting) + +--- + +## Basic Concepts + +### What is curl_hook? + +The `curl_hook` is a type of hook that executes HTTP requests asynchronously after a function is triggered by the LLM. Like other hooks, it runs in the background without blocking the conversation flow. + +### When to Use curl_hook? + +Use `curl_hook` when you need to: +- Notify external systems about conversation events +- Fetch custom data from external APIs during specific nodes +- Update customer records in third-party CRMs +- Trigger webhooks or background jobs +- Integrate with merchant-specific backend services + +### How It Works + +1. User triggers a function (e.g., "confirm_order") +2. The conversation immediately transitions to the next node +3. The `curl_hook` executes asynchronously in the background +4. External API receives the HTTP request +5. Response is logged (but doesn't block conversation) + +--- + +## Configuration + +### Hook Structure + +The `curl_hook` is configured within the `hooks` array of a function in your template JSON: + +```json +{ + "function_name": "your_function_name", + "hooks": [ + { + "name": "curl_hook", + "expected_fields": { + "url": { + "source": "static", + "value": "https://api.example.com/endpoint" + }, + "method": { + "source": "static", + "value": "POST" + }, + "headers": { + "source": "static", + "value": { + "Authorization": "Bearer YOUR_TOKEN", + "Content-Type": "application/json" + } + }, + "body": { + "source": "static", + "value": { + "customer_id": "12345", + "action": "confirmed" + } + }, + "timeout": { + "source": "static", + "value": 10 + } + } + } + ] +} +``` + +### Required Fields + +| Field | Required | Description | Default | +|-------|----------|-------------|---------| +| `url` | **Yes** | The endpoint URL to call | N/A | +| `method` | No | HTTP method (GET, POST, PUT, DELETE, PATCH) | POST | +| `headers` | No | Request headers as key-value pairs | {} | +| `body` | No | Request body (used with POST/PUT/PATCH) | {} | +| `timeout` | No | Request timeout in seconds | 10 | + +### HTTP Methods Supported + +- **GET**: Retrieve data from external API +- **POST**: Send data to external API +- **PUT**: Update resources +- **PATCH**: Partial update of resources +- **DELETE**: Delete resources + +--- + +## Usage Examples + +### Example 1: Simple POST Request + +Send a confirmation to an external webhook: + +```json +{ + "function_name": "confirm_order", + "hooks": [ + { + "name": "curl_hook", + "expected_fields": { + "url": { + "source": "static", + "value": "https://merchant-api.com/orders/confirm" + }, + "method": { + "source": "static", + "value": "POST" + }, + "headers": { + "source": "static", + "value": { + "Authorization": "Bearer sk_test_123456", + "Content-Type": "application/json" + } + }, + "body": { + "source": "static", + "value": { + "order_id": "{order_id}", + "status": "confirmed", + "timestamp": "{{auto}}" + } + } + } + } + ] +} +``` + +### Example 2: GET Request to Fetch Data + +Retrieve customer information from an external API: + +```json +{ + "function_name": "check_account_status", + "hooks": [ + { + "name": "curl_hook", + "expected_fields": { + "url": { + "source": "static", + "value": "https://crm.example.com/api/customers/{customer_id}" + }, + "method": { + "source": "static", + "value": "GET" + }, + "headers": { + "source": "static", + "value": { + "Authorization": "Bearer YOUR_API_KEY", + "Accept": "application/json" + } + } + } + } + ] +} +``` + +### Example 3: Dynamic Data from LLM + +Send cancellation reason inferred by LLM to external API: + +```json +{ + "function_name": "cancel_order", + "properties": { + "cancellation_reason": { + "type": "string", + "description": "Reason for cancellation" + } + }, + "required": ["cancellation_reason"], + "hooks": [ + { + "name": "curl_hook", + "expected_fields": { + "url": { + "source": "static", + "value": "https://api.example.com/orders/cancel" + }, + "method": { + "source": "static", + "value": "POST" + }, + "body": { + "source": "llm", + "value": null + } + } + } + ] +} +``` + +In this example, the entire `body` is sourced from the LLM's function arguments. + +### Example 4: Mixed Static and LLM Sources + +Combine static configuration with LLM-inferred data: + +```json +{ + "function_name": "update_address", + "properties": { + "new_address": { + "type": "string", + "description": "The updated delivery address" + } + }, + "required": ["new_address"], + "hooks": [ + { + "name": "curl_hook", + "expected_fields": { + "url": { + "source": "static", + "value": "https://api.example.com/update-address" + }, + "method": { + "source": "static", + "value": "PUT" + }, + "headers": { + "source": "static", + "value": { + "Authorization": "Bearer API_KEY" + } + }, + "body": { + "source": "static", + "value": { + "order_id": "{order_id}", + "action": "address_update" + } + }, + "new_address": { + "source": "llm" + } + } + } + ] +} +``` + +Here, `body` comes from static config, but `new_address` is added from LLM args. + +### Example 5: Custom Timeout + +For slow external APIs, increase timeout: + +```json +{ + "name": "curl_hook", + "expected_fields": { + "url": { + "source": "static", + "value": "https://slow-api.example.com/process" + }, + "timeout": { + "source": "static", + "value": 30 + } + } +} +``` + +--- + +## Field Sources + +### Static Source + +Use `"source": "static"` when the value is known at template design time and doesn't change per call. + +**Example:** +```json +{ + "url": { + "source": "static", + "value": "https://api.merchant.com/webhook" + } +} +``` + +**When to use:** +- API endpoints +- Authentication tokens +- Fixed header values +- Static request body structure + +### LLM Source + +Use `"source": "llm"` when the value should come from the LLM's function arguments. + +**Example:** +```json +{ + "cancellation_reason": { + "source": "llm" + } +} +``` + +The LLM extracts `cancellation_reason` from the conversation and passes it as a function argument, which is then included in the HTTP request. + +**When to use:** +- User-provided data (addresses, phone numbers, names) +- Dynamic values inferred from conversation +- Variable request parameters +- Context-dependent information + +### Template Variables + +You can use template variables (from `expected_payload_schema`) in static values: + +```json +{ + "body": { + "source": "static", + "value": { + "customer_id": "{customer_id}", + "shop_name": "{shop_name}" + } + } +} +``` + +These variables are substituted during template loading. + +--- + +## Best Practices + +### 1. Use Appropriate HTTP Methods + +- **GET**: For read-only operations (fetching data) +- **POST**: For creating new resources or triggering actions +- **PUT/PATCH**: For updating existing resources +- **DELETE**: For removing resources + +### 2. Handle Authentication Securely + +**❌ Bad:** +```json +{ + "headers": { + "source": "static", + "value": { + "Authorization": "Bearer hardcoded_token_in_template" + } + } +} +``` + +**✅ Good:** +Store tokens in environment variables or secure configuration, then reference them in the template system. + +### 3. Set Reasonable Timeouts + +- Default: 10 seconds +- Fast APIs: 5 seconds +- Slow/batch APIs: 30 seconds +- Never exceed 60 seconds (blocks the system) + +### 4. Log Response Data + +The hook automatically logs: +- Request method and URL +- Response status code +- First 500 characters of response body +- Errors and exceptions + +Check logs to debug failed API calls. + +### 5. Error Handling + +The `curl_hook` is designed to fail gracefully: +- Errors are logged but don't crash the conversation +- Failed requests don't block node transitions +- HTTP 4xx/5xx responses are logged as warnings + +### 6. Avoid Blocking Operations + +Remember: Hooks are **asynchronous** and **fire-and-forget**. Don't use `curl_hook` if: +- You need the response data immediately +- The conversation flow depends on the API response +- You need to verify success before proceeding + +For synchronous operations, consider using a custom handler instead. + +### 7. Test with Mock Endpoints + +Before deploying to production, test your curl_hook configuration with: +- [RequestBin](https://requestbin.com/) +- [webhook.site](https://webhook.site/) +- [Mockoon](https://mockoon.com/) + +### 8. Rate Limiting + +If calling external APIs frequently: +- Check the API's rate limits +- Implement exponential backoff in your backend +- Consider batching requests if possible + +--- + +## Troubleshooting + +### Hook Not Executing + +**Symptoms:** No HTTP requests in logs, no API calls received. + +**Possible Causes:** +1. Hook name typo: Must be exactly `"curl_hook"` +2. Missing `url` field in `expected_fields` +3. Hook not registered in `HookRegistry` + +**Solution:** +```python +# Verify hook is registered +from app.ai.voice.agents.breeze_buddy.template.hooks import HookRegistry +print(HookRegistry.get_all()) # Should include 'curl_hook' +``` + +### HTTP Request Failing + +**Symptoms:** Logs show "Error executing HTTP request" + +**Possible Causes:** +1. Invalid URL +2. Network connectivity issues +3. Timeout too short +4. SSL certificate validation failed +5. Authentication failure + +**Solution:** +- Check logs for specific error message +- Test URL manually with curl/Postman +- Increase timeout if needed +- Verify authentication headers + +### Response is 4xx/5xx + +**Symptoms:** Logs show warning about error status code + +**Possible Causes:** +1. Invalid authentication token +2. Malformed request body +3. API endpoint doesn't exist +4. Rate limit exceeded + +**Solution:** +- Check API documentation +- Verify request format matches API expectations +- Test with same payload using curl/Postman + +### Request Body Not Sent + +**Symptoms:** API receives empty body + +**Possible Causes:** +1. `body` field missing from `expected_fields` +2. HTTP method is GET (doesn't support body) +3. LLM didn't provide required arguments + +**Solution:** +- Ensure `body` is in `expected_fields` +- Use POST/PUT/PATCH for requests with body +- Check LLM function arguments in logs + +### Template Variables Not Substituted + +**Symptoms:** URL/body contains literal `{customer_id}` instead of value + +**Possible Causes:** +1. Variable not in `expected_payload_schema` +2. Variable not provided in lead payload +3. Template not rendered correctly + +**Solution:** +```python +# Check template rendering +print(self.template_vars) # Should contain all expected variables +``` + +--- + +## Advanced Usage + +### Dynamic URL with Variables + +```json +{ + "url": { + "source": "static", + "value": "https://api.example.com/customers/{customer_id}/orders/{order_id}" + } +} +``` + +Variables `{customer_id}` and `{order_id}` will be substituted from payload. + +### Custom Headers per Merchant + +Use template variables in headers: + +```json +{ + "headers": { + "source": "static", + "value": { + "Authorization": "Bearer {merchant_api_key}", + "X-Merchant-ID": "{merchant_id}" + } + } +} +``` + +### Query Parameters in URL + +Include query parameters directly in URL: + +```json +{ + "url": { + "source": "static", + "value": "https://api.example.com/data?customer_id={customer_id}&type=order" + } +} +``` + +--- + +## Complete Example + +Here's a complete node configuration using `curl_hook`: + +```json +{ + "node_name": "confirm_delivery_node", + "task_messages": [ + { + "role": "system", + "content": "Ask the customer to confirm delivery address: {address}" + } + ], + "functions": [ + { + "function_name": "confirm_delivery", + "description": "Customer confirms the delivery address is correct", + "properties": { + "delivery_notes": { + "type": "string", + "description": "Any special delivery instructions from customer" + } + }, + "required": [], + "transition_to": "thank_you_node", + "hooks": [ + { + "name": "update_outcome_in_database", + "expected_fields": { + "outcome": { + "source": "static", + "value": "confirmed" + } + } + }, + { + "name": "curl_hook", + "expected_fields": { + "url": { + "source": "static", + "value": "https://merchant.example.com/api/delivery/confirm" + }, + "method": { + "source": "static", + "value": "POST" + }, + "headers": { + "source": "static", + "value": { + "Authorization": "Bearer {merchant_api_token}", + "Content-Type": "application/json" + } + }, + "body": { + "source": "static", + "value": { + "order_id": "{order_id}", + "customer_id": "{customer_id}", + "status": "confirmed", + "address": "{address}" + } + }, + "delivery_notes": { + "source": "llm" + }, + "timeout": { + "source": "static", + "value": 15 + } + } + } + ] + } + ] +} +``` + +In this example: +- The hook will POST to the merchant's API +- Static fields (order_id, customer_id, status, address) come from template variables +- Dynamic field (delivery_notes) comes from LLM +- Custom timeout of 15 seconds +- Authentication token from template variable + +--- + +## Security Considerations + +### 1. Sensitive Data + +**Never** hardcode sensitive data in templates: +- API keys +- Authentication tokens +- Passwords +- Private keys + +Instead, use environment variables or secure configuration management. + +### 2. HTTPS Only + +Always use HTTPS URLs for sensitive data: +```json +✅ "https://api.example.com/secure" +❌ "http://api.example.com/insecure" +``` + +### 3. Input Validation + +The external API should validate all incoming data. Don't trust LLM-inferred values blindly. + +### 4. Rate Limiting + +Implement rate limiting on your external endpoints to prevent abuse. + +--- + +## Monitoring and Logging + +### What Gets Logged + +The `curl_hook` logs: + +1. **Info Level:** + - Hook execution start + - HTTP request method and URL + - Response status code + - Hook completion + +2. **Debug Level:** + - Field extraction (static vs LLM) + - Request configuration + - First 500 chars of response body + +3. **Warning Level:** + - HTTP 4xx/5xx responses + - Missing LLM arguments + - Missing expected fields + +4. **Error Level:** + - Missing URL + - No aiohttp session + - Network errors + - Exceptions + +### Log Format Example + +``` +INFO: Executing HTTP POST request to https://api.example.com/webhook for function 'confirm_order' +DEBUG: Field 'url': using static value 'https://api.example.com/webhook' for function 'confirm_order' +DEBUG: Field 'cancellation_reason': using LLM-inferred value 'Out of stock' for function 'confirm_order' +INFO: HTTP POST request to https://api.example.com/webhook completed with status 200 for function 'confirm_order' +``` + +--- + +## Summary + +The `curl_hook` enables powerful external integrations without code changes: + +✅ **Benefits:** +- No code deployment needed +- Configurable per merchant +- Asynchronous (non-blocking) +- Flexible field sources +- Comprehensive logging + +⚠️ **Limitations:** +- Fire-and-forget (can't use response in conversation) +- Not suitable for synchronous operations +- Requires external endpoint to be available + +📚 **Next Steps:** +1.
