Request parameters for add_all_products_to_open_campaign
Add all eligible products into the Open Campaign. We will only return the general error that caused the whole task failure, without returning the specific error for each product in the v2.ams.get_open_campaign_batch_task_result API. If you want to get the result for each products, you can use v2.ams.batch_add_products_to_open_campaign by pagination manually, or check the product status by using the GET API after the task progress turn to 100%.
