reverseRoutingboolean nullable

This feature is only available to marketplace operators.

With Mollie Connect you can charge fees on payments that your app is processing on behalf of other Mollie merchants, by providing the routing object during payment creation.

When creating refunds for these routed payments, by default the full amount is deducted from your balance.

If you want to pull back the funds that were routed to the connected merchant(s), you can set this parameter to true when issuing a full refund.

For more fine-grained control and for partial refunds, use the routingReversals parameter instead.

testmodeboolean nullable

Whether to create the entity in test mode or live mode.

Most API credentials are specifically created for either live mode or test mode, in which case this parameter must not be sent. For organization-level credentials such as OAuth access tokens, you can enable test mode by setting testmode to true.
