Makini sends webhooks for several event types: sync completion (successful or failed), connection authentication required (when credentials need renewal), connection status changes (online/offline), and system errors requiring attention. Each webhook payload includes the event type, timestamp, connection ID, and event-specific details like error messages or affected entities. You can configure which events trigger webhooks on a per-connection basis. For workflow-based integrations using Makini Flows, you can also set up custom webhooks triggered by specific conditions in your business logic, providing granular control over real-time notifications.
The `RATE_LIMIT_EXCEEDED` error indicates you've exceeded the API rate limit for the connection or account. Rate limits are typically set per connection and per time window (usually per minute). When you hit a rate limit, the response includes a `Retry-After` header indicating when you can retry the request. Implement exponential backoff in your retry logic to avoid immediately hitting the limit again. If you consistently hit rate limits, review your API usage patterns—you may be making unnecessary requests, polling too frequently, or could benefit from webhook-based synchronization. For legitimate high-volume needs, contact us to discuss increasing your rate limits.
Connection-specific errors often relate to system configuration, permissions, or connectivity issues. Common scenarios include: the system is offline or unreachable, credentials have expired, API rate limits on the source system, or permission changes in the source system. Use the connection status endpoint to check connection health before making API calls. Implement circuit breaker patterns—if a connection repeatedly fails, temporarily stop making requests to avoid cascading failures. Log connection-specific errors separately to identify problematic connections. When errors occur, check if the issue affects all operations or specific entity types, which helps narrow down permission or configuration issues. For on-premises systems, verify network connectivity and firewall rules. Contact support if connection errors persist, providing the connection ID and affected operations.
Makini provides sandbox connections for testing without affecting production systems. Sandbox connections include sample data representing common scenarios: standard purchase orders, orders with custom fields, orders in various states (draft, approved, completed), and error cases like invalid vendors or out-of-stock items. Sandbox data is read-only for safety—write operations return success responses without modifying data. This allows thorough testing of your integration logic without risk. For testing with specific systems, we recommend using dedicated test instances of the actual systems (like SAP sandbox environments) connected through Makini, which provides the most realistic testing experience.
