Payments API

Global payments, in one REST call.

Put international receiving, conversion and payment inside your product. The corridors, the compliance and the authorized partners stay on our side.

Recursos

What you get.

Quote before the order

Request the price for the pair, receive a quote with a set validity and only then execute. The price shows up before confirmation.

Payments in six currencies

One call to pay in USD, EUR, BRL, MXN, GBP or COP. The API picks the right local rail for the destination.

Receiving accounts

Issue international accounts in your customer's name and get the credit via webhook as soon as the funds land.

Signed webhooks

Receiving, conversion, settlement and compliance events, HMAC-signed and idempotent, with automatic retry on failure.

Reconciliation by reference

Tag every order with your own ID and get everything back with it: reconciliation with no spreadsheet in between.

Assisted sandbox

An environment that mirrors production, with synthetic data and simulated corridors, enabled by the technical team during integration.

All included

Everything you need, with no surprise bundle.

Use cases
Platforms with sellers abroad

Get paid by the local buyer and pass it on to the seller in their country, with one call per payout and reconciliation by your reference.

Fintechs and gateways

Offer international receiving and cross-border payments in your product, without building your own corridors, custody or compliance.

ERPs and automated finance

Trigger supplier payments straight from your system and get the confirmation via webhook, with nobody opening a bank portal.

Frequently asked questions

Common questions.

Do I need to build crypto infrastructure?+

No. You integrate the API and work in currency: request a quote, create the order and receive the webhook. The stablecoin is the rail underneath; Lexxen and its partners handle custody, networks and liquidity.

How does authentication work?+

Calls are authenticated by key and webhooks are HMAC-signed, so you can verify the event really came from Lexxen. Events are idempotent and retried on failure.

Is there a test environment?+

Yes, a sandbox that mirrors production with synthetic data and simulated corridors. Access is enabled by the technical team during integration.

Where is the documentation?+

At cashout.lexxen.com/docs, with the reference for quotes, payment orders, receiving accounts and webhooks.
