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.
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.
When a system becomes unavailable, Makini detects the connectivity failure and marks the connection status accordingly. Scheduled syncs will fail with connectivity errors. API requests to the connection will return error responses indicating the system is unreachable. Makini continues attempting scheduled syncs using exponential backoff—initial retries happen frequently, then progressively less often to avoid overwhelming the system when it comes back online. Webhooks notify you of the connection status change. When the system comes back online, normal operations resume automatically. For temporary outages, no action is required. For extended outages, you may want to notify the customer. Connection credits remain consumed during outages since the connection configuration persists.
Use the following OpenSSL command to generate both private and public keys:
openssl req -new -x509 -newkey rsa:4096 -keyout private.pem -sigopt rsa_padding_mode:pss -sha256 -sigopt rsa_pss_saltlen:64 -out public.pem -nodes
Upload the public.pem to NetSuite and keep the private.pem secure for use in Makini Link.
