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.
Makini supports create, read, update, and delete (CRUD) operations, though availability varies by system and entity type. Most systems support creating and updating core entities like purchase orders, work orders, and inventory items. Read operations are universally supported across all entity types. Delete operations are less commonly supported due to system constraints—many industrial systems use soft deletes or status changes rather than true deletion. Update operations may be limited to specific fields depending on system configuration and business rules. For example, some systems prevent modifying purchase orders after approval. We recommend validating specific operation support for your use case during the technical deep dive.
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.
Makini uses cursor-based pagination for retrieving large datasets. API responses include a next_cursor field when additional results are available. To retrieve the next page, include the cursor value in your next request: GET /api/v1/purchase-orders?cursor=CURSOR_VALUE. Cursor-based pagination is more reliable than offset-based pagination because it handles data changes between requests—if records are added or deleted while you're paginating, you won't miss records or see duplicates. Page size is configurable up to a maximum limit (typically 100-500 records per page depending on entity type). For optimal performance, use the largest page size your application can handle efficiently. The API response also includes total count when available from the source system.
