Unlinked links disappear from get/list and are rejected for new money movement; Account Link ids remain referenceable by history. Repeating the call returns the same final snapshot. Unlinking a link that never finished activating cancels its pending session and returns that same `unlinked` snapshot. A link busy with an in-flight provider operation (activation, reconnect, or an earlier unlink attempt) returns `Unavailable`; retry shortly. Unlinking also severs the provider-side connection; if the provider refuses (for example, transactions are still settling) the link is not unlinked. It keeps its current status, and the call returns `bank_link_provider_rejected`. If the provider outcome is unknown (for example, the provider was unreachable) the call also returns `Unavailable` and the link stays busy until the pending attempt expires; retry after that to finish the unlink. ## OpenAPI ````yaml https://d2588n1sy4m36o.cloudfront.net/uat/merged/openapi.json delete /v1/accounts/{account_id}/funds/bank-links/{bank_link_id} openapi: 3.1.0 info: title: PWS Public API version: '1' description: >- Integrate with Payward Services to onboard users, manage accounts and funds, trade assets, and receive event notifications. contact: name: Payward Services servers: - url: https://api.sandbox.services.payward.com security: [] tags: - name: Assets description: List the assets PWS is willing to swap. x-displayName: Assets - name: Conversions description: >- Rule-driven and on-demand fiat ↔ crypto value movement, including conversion rules and deposits. x-displayName: Conversions - name: Auto Earn description: >- Manage Auto Earn preferences and retrieve allocation and reward information. x-displayName: Auto Earn - name: Bonded Earn description: >- Allocate funds to and deallocate funds from bonded earn strategies, review allocations, and track request status. x-displayName: Bonded Earn - name: Funding description: >- Discover deposit and withdrawal options, manage deposit addresses, and move funds between accounts. x-displayName: Funding - name: Derivative transfers description: >- Move funds between an account's spot balance and the same owner's futures balance. x-displayName: Derivative transfers - name: Portfolio description: 'Inspect a customer''s portfolio: balances, valuations, and transactions.' x-displayName: Portfolio - name: Ramp description: >- Support Ramp flows with discovery, quotes, limits, and hosted checkout experiences. x-displayName: Ramp - name: Reports description: Settlement and reconciliation reports for the partner. x-displayName: Reports - name: Swaps description: Account-funded quotes that lock a price until they expire or are executed. x-displayName: Swaps - name: Onchain quotes description: Wallet-funded quotes that return the data needed to settle onchain. x-displayName: Onchain quotes - name: Price trigger swaps description: Swaps that wait for a target price before submitting a trade. x-displayName: Price trigger swaps - name: Travel Rule verifications description: Travel Rule address ownership verification flows. x-displayName: Travel Rule verifications - name: Users description: >- User onboarding and status flows that the partner manages. - **Create User** provisions an account-owned user from an external reference and optional email. - **Get User** retrieves the user's profile, verification status, and required actions.
