Only blocks reported with `blockLiftable: true` can be lifted this way; the rest return `409 CARD_BLOCK_NOT_LIFTABLE` and need Reap support. A card frozen before it was blocked returns to `FROZEN`, not `ACTIVE`, and a card unfrozen while blocked returns to `ACTIVE`. Idempotent; unblocking a card that holds no block returns it unchanged. ## OpenAPI ````yaml /api-reference/openapi.json post /cards/{id}/unblock openapi: 3.1.0 info: title: Reap API version: 1.0.0 description: Reap platform API servers: - url: https://sandbox.api.reap.global description: Sandbox - url: https://prod.api.reap.global description: Production security: - bearerAuth: [] tags: - name: Accounts - name: Activities - name: Card Designs - name: Card Shipments - name: Card Transactions - name: Cards - name: Companies - name: Crypto Deposits - name: Disputes - name: Fiat Deposits - name: Fraud Alerts - name: Policies - name: Simulation - name: Users - name: Virtual Asset Postings - name: Virtual Assets - name: Webhooks paths: /cards/{id}/unblock: post: tags: - Cards summary: Unblock card description: >- Lifts a block.
