64015: Pay: `<Pay>` verb is missing a needed Parameter

A 64015 Error is an indication that the configured connector for the payment method is missing one of the Parameter needed in the <Pay> verb.

The connector needs a specific Parameter in the <Pay> verb

The required parameters for the connector are listed in the "Description" section of the connector. The parameters should be passed inside the <Pay> verb.

Example:

1
<Pay>
2
  <Parameter name="Parameter Name" value="Parameter Value" />
3
</Pay

• MerchantAccountId is required to be passed via a <Parameter> noun for all Braintree <Pay> executions. This value can be found in the Braintree console by navigating to Settings (gear icon) -> Business.
• If passing a description as a parameter in <Pay>, you must also pass the following fields via separate <Parameter> nouns: name, kind, quantity, totalAmount, unitAmount. If you received this error you either left one of these fields out, or passed an invalid value for one of them. See Braintree Documentation for more information.
