 * RetrieveMerchantCustomAttribute

 * Retrieves a [custom attribute]($m/CustomAttribute) associated with a merchant.

You can use the `with_definition` query parameter to also retrieve the custom attribute definition

in the same call.

To retrieve a custom attribute owned by another application, the `visibility` setting must be

`VISIBILITY_READ_ONLY` or `VISIBILITY_READ_WRITE_VALUES`.
