autoTopUp

The auto top-up policy's configuration.

Source: packages/paykit/src/Subscription/AutoTopUp.policy.ts Kind: Layer

The auto top-up policy’s configuration. The pack is catalog data by id; the threshold is the tier’s own field (Tier.topUp), so a free tier and an enterprise tier refill on the lines their pools need. The cooldown is the deployment’s: it bounds how often one account can be charged, not what the pack costs.
