Authentication errors (401 status code) typically occur for a few reasons: the API token is invalid or expired, the underlying system credentials have changed, the system requires reauthorization, or the token lacks necessary permissions. First, verify you're including the token correctly in the Authorization header. Check the connection status in the Makini dashboard—if it shows as requiring reauthorization, the customer needs to reconnect. If credentials were recently changed in the source system, you'll need to reconnect to obtain a new token. For persistent issues, check if the system account has sufficient permissions to perform the requested operation. If the problem continues, contact support with the request ID for investigation.
Write operation limitations vary by system. Common limitations include: field-level restrictions (some fields may be read-only), business rule validation (orders may require certain fields or valid vendor codes), permission requirements (the connected account needs specific permissions), timing restrictions (some systems prevent modifications after certain workflow states), and rate limits on write operations. Custom fields in target systems may not be writable through standard APIs. Some systems have transactional requirements—for example, purchase order line items must be created in the same transaction as the order header. During implementation, we identify write operation limitations for your specific use cases and design workflows that work within those constraints.
Disconnecting a connection can be done through the Makini dashboard or API. In the dashboard, navigate to the connection and select disconnect. Via API, call the disconnect endpoint with the connection ID. Disconnecting immediately invalidates the API token and stops all scheduled syncs and workflows for that connection. The connection credits used are returned to your pool and become available for new connections. Disconnecting does not delete historical data that was previously synced—that remains accessible until you choose to delete it. Customers can reconnect the same system at any time, which will create a new connection with a new API token. Use disconnection for customers who churn or when permanently retiring a connection.
You have two options:
• Option A: Upload the Makini public certificate (available in the Resources section of the guide)
• Option B: Generate your own self-signed certificate using OpenSSL and upload the public key to NetSuite
