This idea has been merged into another idea. To comment or vote on this idea, please visit PL-I-223 Admin API: client generation and batch support.
Currently, the Admin Web APIs are single operation only (e.g. "update a single product", "delete a single category", etc). From a performance perspective, it would be beneficial if batch operations (e.g. "delete these 200 categories", "update fields X and Y on these 6000 products", etc.) could be added as well.
