Where is it used in Paylike?

A descriptor is set in the following places:

1. On your merchant account
2. On a transaction for the reservation
3. On each capture of a transaction

The descriptor on the account (1) acts as a default if you do not supply a descriptor for the transaction (2).

If you omit the descriptor for a capture (3) it will default to that on the transaction (2).

As such, only the merchant account's descriptor is mandatory.
