Lifecycle
- Onboarding — The customer applies for a product. See Onboarding for the card flow. On approval and signing, an engagement is created for that product.
- Active engagement — The customer uses the product. The partner can initiate operations against the engagement, such as a Credit Limit Increase on a card engagement.
- Closure — The engagement ends when the product relationship is terminated (closed by the customer, defaulted, or otherwise wound down).
