PWS exposes Swaps (institutional FX-style trading), Conversion rules (rule-driven fiat ↔ crypto value movement), retail-style Quotes and Price Trigger Swaps, end-user Users / Verifications, Travel Rule address ownership verification, Funds (deposits, withdrawals, addresses, transactions), Portfolio, Earn, Reports, Webhooks, and Ramp (hosted fiat-to-crypto on-ramp checkout). All requests must be authenticated. All monetary values are decimal strings; all timestamps are ISO 8601 UTC. List endpoints are cursor-paginated. Errors follow a uniform shape (see `*ErrorResponse` schemas). version: v1 contact: name: Payward Services API Support url: https://docs.payward.com email: api-support@payward.com servers: - url: https://api.services.payward.com description: Production security: - ApiKey: [] ApiSign: [] ApiNonce: [] tags: - name: Users description: >- User onboarding and status flows that the partner manages. - **Create User** provisions a user with an email and external reference. - **Get User** retrieves the user's profile, verification status, and required actions.

Two resources model a connection: - A **Bank Link** is the connection between one account and one banking institution. Create it to get a hosted-widget URL, and send the user there to choose their institution and approve access. One account can hold many Bank Links. - An **Account Link** is one bank account — a checking account, for example — that the user shared through that connection. One Bank Link owns one or more Account Links. Use `account_link_id` to reference the bank account when you move money. Both ids are opaque handles. Provider identifiers, access tokens, owner names, and raw bank numbers are never exposed. Eligibility is evaluated on every read, and ownership must match: the bank account's holder must match the account's verified holder. An account that fails ownership validation reports `ineligible` with the reason `name_mismatch`. Unlinking is permanent. Linking the same bank account again creates a new Bank Link and a new `account_link_id`; old ids stay valid only for reading history. - name: Portfolio description: 'Inspect a customer''s portfolio: balances, valuations, and transactions.' - name: Price trigger swaps description: Limit-style orders that execute when a configured price trigger is met. - name: On-chain swaps description: >- Wallet-funded onchain quote trading for xStock and USDC pairs.
