Nothing was credited, so nothing is taken back. Callable by the member the deposit was addressed to or the account owner, with `can_withdraw` and the same TOTP rule as withdrawals. Returns as soon as the crypto service accepts the request. The outcome arrives asynchronously: on success the transaction becomes `canceled` and `deposit_data.refund` carries `tx_hash`, `blockchain_url` and the `amount` sent; on failure `deposit_data.refund.status` is `failed` with an `error_code` and the request can be sent again. Poll POST /transactions for the outcome. Finup charges no fee, but the network fee is taken out of the transfer (on Tron up to 3 USDT). ## OpenAPI ````yaml /openapi.json post /transactions/{transaction_id}/aml-refund openapi: 3.1.0 info: title: Finup Public API version: 1.0.0 description: >- Client-facing Finup API reference generated from current public endpoint metadata. servers: - url: https://api.finup.io/backend description: Production security: [] tags: - name: Accounts description: Current account, account setup, and account capabilities. - name: Transactions description: Account transaction lists and aggregates. - name: Cards description: Card issuing, listing, funding, and status changes. paths: /transactions/{transaction_id}/aml-refund: post: tags: - Transactions summary: Refund a deposit blocked by the AML check description: >- Sends a crypto deposit that failed the AML check (`deposit_data.aml_declined`, status `declined`) back out to the given address.
