Learn about all the additional information about your customer you can send.
In some cases, we require additional information regarding the customer and the purchase in order to make a correct risk assessment. This information, called extra merchant data (EMD), may consist of data about the customer performing the transaction, the product/services associated with the transaction, or the seller and their affiliates.
Depending on the business category or the type of goods sold, you must provide specific EMD packages. Learn what information is mandatory in each package and how to send it to us.
Find out more about the different data fields for each package by checking the attachments specification.
You need to include the extra merchant data in an attachment property of the payload when getting authorization or updating an order.
Add the relevant data based on the specification and your product vertical. To know which product vertical is right for you, contact merchant support.
The following example shows EMD for recurring orders, which require subscription details.
