Import a product structure from JSON data. This will update the specified
product with the provided data structure.

Warning: This operation will delete all existing tasks, steps, scripts, translations, resources, and other product-related data, then replace them with the imported data. The product record itself is updated (not deleted). Use with caution.

Critical Requirements:

• The imported JSON must be exported from the same product (same product ID and bundle_id combination)
• The bundle_id in the JSON must match the target product's bundle_id exactly
• If bundle_id does not match, the import will be rejected with a 400 error
• The JSON must include the product.bundle_id field (included in all exports)
• GUIDs are preserved from export to import (not regenerated)
• Empty arrays (e.g., tasks: []) will not create any entries for that entity type

Validation Rules:

• bundle_id mismatch: Import rejected (prevents importing wrong product data)
• Missing bundle_id: Import rejected (indicates invalid export format)
• Inherited Copilots: Cannot be imported (both source and target)

Limitations:

• Only one import operation can run per product at a time (concurrent imports are blocked)
• Large products may take several minutes to import; configure HTTP client timeouts accordingly
• If the import operation fails partway through, the product may be left in a partial or empty state; retry the import until it succeeds

Best Practices:

• Export the product before importing to create a backup
• Do not modify the exported JSON structure (only modify data contents if needed)
• If the import fails, you can retry immediately (the lock is released on failure)
• Check the response summary and errors fields for import results
• Retry failed imports until they succeed to ensure complete data restoration

Common use cases:

• Restore from backup (same product)
• Update product structure (same product)
• Transfer between environments (same product, different server)

Import Structure:
The data object must match the structure returned by the export endpoint.

Note: For complex imports with nested structures (tasks, steps, resources, etc.),
use the code samples provided below rather than the form-based interface. Copy the
cURL, JavaScript, Python, or PHP example and replace the JSON payload with your exported data.
