WEBHOOK
The vl.program.card_definition.unassigned event indicates that a card definition was unassigned from a Loyalty v2 program.
This page documents only the event data nested under data. See Introduction to webhooks for the shared webhook structure, and Workflows webhooks for the full Workflows webhook payload.
This event can trigger a workflow when Loyalty activity is configured with the Programs group and the vl.program.card_definition.unassigned activity type. If the workflow reaches a Webhook callout action, Voucherify sends a webhook to the action’s target URL. Workflows send this activity in the data.trigger object. This operation also creates a separate vl.card_definition.unassigned activity. Use the Card definition unassigned event to handle that event type.
