Import numbers, manage calls, and handle SMS/MMS. **Other SIP Providers**: Connect to other Session Initiation Protocol (SIP) providers for call routing and management. **Provider Configuration**: Configure authentication, endpoints, and settings for each provider. ### CRM Systems **HubSpot**: Integrate with HubSpot to sync contact data, create records, and update customer information during calls. **Salesforce**: Connect to Salesforce to access and update customer records, create leads, and log interactions. **Custom CRM**: Build custom integrations with your CRM system using webhooks and API calls. ### Communication Platforms **Slack**: Send notifications to Slack channels when calls complete, errors occur, or important events happen. **Email**: Send email notifications, summaries, or transcripts after calls. **SMS/MMS**: Handle text messaging through integrated providers. ### Database Systems **Custom Databases**: Connect to your databases to fetch customer data, update records, or query information during calls. **Data Warehouses**: Integrate with data warehouses for analytics and reporting. **Real-time Data**: Access real-time data during conversations to provide up-to-date information. ### API Integrations **REST APIs**: Connect to any REST API to fetch data or trigger actions. **GraphQL APIs**: Integrate with GraphQL endpoints for flexible data queries. **Webhooks**: Receive webhooks from external systems to trigger workflows or update state. **Authentication**: Handle various authentication methods (API keys, OAuth, JWT, etc.). ## Integration Methods ### Function Calls Functions are the primary way agents interact with external systems: **Function Definition**: Define functions that agents can call during conversations. **API Endpoints**: Functions can call external API endpoints to fetch or update data. **Data Transformation**: Transform data between formats as needed. **Error Handling**: Handle API errors gracefully and provide fallback behavior. ### Webhooks Webhooks allow external systems to notify Freyavoice AI: **Incoming Webhooks**: Receive webhooks from external systems to trigger workflows or update state. **Outgoing Webhooks**: Send webhooks to external systems when events occur (call completed, error, etc.). **Webhook Security**: Validate webhook signatures to ensure authenticity. **Webhook Retries**: Handle webhook delivery failures with retry logic. ### Direct API Calls Make direct API calls from workflows: **HTTP Requests**: Make GET, POST, PUT, DELETE requests to external APIs. **Authentication**: Handle authentication for protected APIs. **Response Processing**: Process API responses and use data in workflows. **Error Handling**: Handle API failures and timeouts gracefully. ## Common Integration Patterns ### Customer Data Lookup **Pattern**: Look up customer information at the start of a call to personalize the conversation. **Implementation**: Function calls to CRM or database to fetch customer data. **Usage**: Use customer data to personalize greetings, access order history, or provide account information. ### Order Processing **Pattern**: Process orders or transactions during calls. **Implementation**: API calls to order management systems to create, update, or query orders. **Usage**: Agents can take orders, check order status, or process returns during calls. ### Appointment Scheduling **Pattern**: Schedule appointments or meetings during calls. **Implementation**: Integration with calendar systems (Google Calendar, Outlook, etc.) to check availability and book appointments. **Usage**: Agents can check availability, suggest times, and confirm appointments. ### Notification Systems **Pattern**: Send notifications when important events occur. **Implementation**: Webhooks or API calls to notification services (Slack, email, SMS). **Usage**: Notify teams when calls complete, errors occur, or important milestones are reached. ### Data Synchronization **Pattern**: Keep data synchronized between systems. **Implementation**: Bidirectional sync between Freyavoice AI and external systems. **Usage**: Sync contact information, call history, or other data between systems. ## Integration Best Practices ### Security **Secure Credentials**: Never expose API keys or credentials in code. Use secure storage and environment variables. **Authentication**: Use proper authentication methods (OAuth, API keys, JWT) for all integrations. **Data Encryption**: Encrypt sensitive data in transit and at rest. **Access Control**: Limit integration access to only what's necessary. ### Error Handling **Graceful Degradation**: Design integrations to fail gracefully. If an external system is unavailable, the agent should still function. **Retry Logic**: Implement retry logic for transient failures. **Error Logging**: Log integration errors with sufficient context for debugging. **User Communication**: Communicate integration failures to users in helpful, non-technical ways. ### Performance **Caching**: Cache frequently accessed data to reduce API calls and improve performance. **Async Processing**: Process non-critical integrations asynchronously to avoid blocking conversations. **Rate Limiting**: Respect API rate limits and implement backoff strategies. **Connection Pooling**: Reuse connections when possible to improve performance. ### Testing **Test Integrations**: Thoroughly test all integrations before deploying to production. **Mock Services**: Use mock services during development to avoid hitting production APIs. **Integration Tests**: Create automated tests for critical integrations. **Monitor Production**: Continuously monitor integrations in production for issues. ## Setting Up Integrations ### Telephony Integration (Twilio) 1. **Get Credentials**: Obtain Account SID and Auth Token from Twilio 2. **Connect in Freya**: Add credentials in the Integrations section 3. **Verify Connection**: Test the connection to ensure it works 4. **Import Numbers**: Import phone numbers from your Twilio account ### CRM Integration (HubSpot) 1. **Create API Key**: Generate an API key in HubSpot 2. **Configure in Freya**: Add API key in workspace integrations 3. **Define Functions**: Create functions that interact with HubSpot 4. **Test Integration**: Test functions to ensure they work correctly ### Custom API Integration 1. **Review API Documentation**: Understand the API endpoints and authentication 2. **Create Functions**: Define functions that call the API 3. **Handle Authentication**: Implement proper authentication 4. **Test Thoroughly**: Test all API interactions ## Monitoring Integrations ### Health Checks **Connection Status**: Monitor connection status for all integrations. **Response Times**: Track API response times to identify performance issues. **Error Rates**: Monitor error rates to catch integration problems early. **Usage Metrics**: Track integration usage to understand patterns and optimize. ### Alerts **Failure Alerts**: Set up alerts for integration failures. **Performance Alerts**: Alert when response times exceed thresholds. **Error Alerts**: Get notified of integration errors immediately. ## Next Steps Explore advanced features like AI Studio, simulations, and analytics.
