Amz-sp-api提供了CreateSupportTicketAPI来创建一个新的支持工单。以下是一个简单的代码示例：

import amz_sp_api

# Replace with your AWS access key, secret key, and refresh token
amz_sp_api.Configuration.access_key = 'YOUR_ACCESS_KEY'
amz_sp_api.Configuration.secret_key = 'YOUR_SECRET_KEY'
amz_sp_api.Configuration.refresh_token = 'YOUR_REFRESH_TOKEN'

# Initializing client
support_api = amz_sp_api.SupportApi()
marketplace_id = 'YOUR_MARKETPLACE_ID'

# Creating a new support ticket
create_ticket_request = amz_sp_api.models.CreateSupportTicketRequest()
create_ticket_request.marketplace_id = marketplace_id
create_ticket_request.contact_reason_code = 'TECHNICAL_SUPPORT'
create_ticket_request.case_type = 'CUSTOMER_SERVICE'
create_ticket_request.category_code = 'SELLER_CENTRAL'
create_ticket_request.communication_body = 'I have an issue with my seller central account.'
create_ticket_response = support_api.create_support_ticket(create_ticket_request)

需要替换代码中的API密钥和刷新令牌，以及设置适当的marketplace_id。create_ticket_request中的其他字段也应该根据实际情况进行修改。
