Get access to MetaData

You have the option to send MetaData alongside the transaction. Those are Key-Value pairs that can also be used in Email Templates. More information can be found here: https://app-wallee.com/en-gb/doc/api/web-service#_meta_data

In order to use the templates you can access them via the transaction object: 

{{ transaction.metaData.INDEX }}

You can access the resources via your space > resources.
