​
New Quote Parameters: country, rail, and forwardingDays

The POST /api/partner/v2/quotes endpoint now supports three new optional fields:
  • country — Override the destination country when a currency is shared across multiple regions (e.g. USD in US vs. DO).
  • rail — Specify the payment rail for the transaction (SPEI, ACH, WIRE, SEPA, SWIFT).
  • forwardingDays — Set T+N forwarding days (0–4) for MXN OTC settlement scheduling.
These fields give partners finer control over quote generation for multi-country and multi-rail flows.

​
New Off-Ramp Execute Endpoint

Added POST /api/partner/v2/off-ramp/execute — a new endpoint that executes a previously created off-ramp transaction. After crypto funds are received at the destinationWalletAddress, call this endpoint to trigger the fiat payout to the user’s bank account.This enables partners to separate transaction creation from execution, supporting manual verification steps or automated workflow orchestration.See the Off-Ramp Execute reference for full details.

Quote Locking Available for All MXN Transactions

Previously, quote locking was blocked for Mexico transactions exceeding $50,000 MXN. This restriction has been removed — partners can now lock exchange rates on MXN transactions of any amount, just like any other currency.A different pricing tier still applies for transactions above $50,000 MXN, so please account for this when generating quotes for large amounts.
