/api/v1/partner/orders/{order_id}

Get the current status, amounts, and full timeline for a specific order. The next_action field indicates what the partner must do to advance the order. null means no action is required from the partner at this stage — the order is waiting for the counterparty (e.g. the buyer to submit fiat payment proof).

The allowed_actions array lists all API actions the partner can perform at the current status. An action can be in allowed_actions even when next_action is null — this means the action is optional. For example, confirm-fiat-received is available at crypto_received as a fast-track: if you already know the fiat has arrived (via your own systems), you can confirm immediately without waiting for the buyer's payment proof flow to complete.

Order flow summary:

Status	next_action	Who acts
created	—	Partner (or wait for vendor match)
awaiting_crypto_transfer_authorization	authorize_crypto_transfer	Partner
crypto_transfer_authorization_pending	—	System (on-chain confirmation)
crypto_received	—	Buyer submits fiat payment proof
fiat_payment_started	—	System reviews proof
fiat_payment_review_started	—	System accepts/rejects proof
awaiting_fiat_received_confirmation	confirm_fiat_received	Partner
completed	—	—

Fiat settlement and confirmation:

You can call confirm-fiat-received at any time after crypto is in escrow. You do not need to wait for a system notification. If you know through your own systems that the recipient has received the fiat payment, confirm immediately.

Some liquidity providers also send automatic settlement confirmations. When this happens, the order moves to completed on its own. If you already confirmed manually, the auto-confirmation is a no-op. If the auto-confirmation arrives first, your manual confirm call is also a no-op. Both paths are safe.

How to implement:

• Always implement a confirm-fiat-received call in your flow.

• Listen for webhooks. If you receive status=completed, no further action needed.

• If next_action=confirm_fiat_received, call confirm-fiat-received when you know fiat has been received.

• Do not wait for next_action if you already have confirmation from your own banking or payment systems.

Possible statuses: created, awaiting_liquidity_provider, awaiting_crypto_transfer_authorization, crypto_transfer_authorization_pending, crypto_received, fiat_payment_started, awaiting_fiat_received_confirmation, fiat_received_confirmed, crypto_release_pending, completed, cancelled, failed, price_changed_requote_needed.

/api/v1/partner/orders/{order_id}/authorize-crypto-transfer

Submit signed EIP-712 forward_request to authorize transfer of order crypto to escrow.

Security note: Your private key is never sent to the API. The SDK uses it locally to construct and sign the EIP-712 ForwardRequest on your machine. Only the resulting signature and the unsigned forward_request fields are submitted. You can verify this by reading the SDK source code.

Recommended: use SDK helper files (only 4 arguments needed):

• Python: https://github.com/Unigox/sdk_python/blob/main/partner_authorize_crypto_transfer_sdk.py

• JavaScript: https://github.com/Unigox/sdk_javascript/blob/main/partner_authorize_crypto_transfer_sdk.js

The SDK automatically fetches all required parameters (chain, token, forwarder, escrow address, RPC URL) from the transfer-authorization-parameters endpoint.

SDK helper options:

• End-to-end one call: authorize_crypto_transfer(...) / authorizeCryptoTransfer(...)

• Build unsigned request only: build_forward_request(...) / buildForwardRequest(...)

• Sign existing request only: sign_forward_request(...) / signForwardRequest(...)

• Build full request body {forward_request, signature}: build_authorize_crypto_transfer_payload(...) / buildAuthorizeCryptoTransferPayload(...)

Manual implementation: call GET /transfer-authorization-parameters first, then build the EIP-712 typed data and sign with your partner wallet private key locally.

Confirm fiat received

/api/v1/partner/orders/{order_id}/confirm-fiat-received

Confirm that the recipient has received the fiat payment for an off-ramp order. This triggers the crypto release from escrow.

Call this endpoint as soon as you know fiat has been received. You do not need to wait for a system prompt. If you have confirmation from your own banking or payment systems, confirm immediately.

This endpoint is idempotent. If the order already completed (via automatic settlement confirmation from the liquidity provider), calling this returns the current order status with no side effects.
