Question:

What is PMS?

Answer:

If your identity with the Alipay contract is an Acquirer, your integration logic will include the concepts of secondary merchants and stores.

You will have to maintain your secondary merchants and stores in Alipay's system and pass the information in every transaction request.

PMS means the ID of you, your secondary merchant, and the store under your secondary merchant.

In the fileds of interfaces, P is partner, M is secondary_merchant_id, S is store_id.

A pair of PMS can find your corresponding store in Alipay system. Alipay's API documents or technical support staff will refer to your store or its ID by PMS.

问题：

什么是PMS？

解答：

如果您与支付宝签约的合约中，身份是支付机构，则您的集成逻辑中会包含二级商户以及店铺的概念。

您需要对二级商户和店铺进行报备，并在请求中传入二级商户或者店铺对应的id。PMS分别表示您，您的二级商户，您二级商户名下的店铺，三者的id。

在接口的参数中，P为参数partner，M为参数secondary_merchant_id，S为参数store_id。

一组PMS能在支付系统中找到您对应的店铺，支付宝的文档或者技术支持人员会以PMS指代您的店铺，或其ID信息信息。
