# Getting Started

Welcome 👋 The Melio B2B Payouts API lets you move money to your payees - collect funds, pay out on any rail, and track every payment, with compliance and delivery handled for you. This page walks you through joining the beta and getting your API key.

<Info>
  **The Melio B2B Payouts API is currently in private beta.** Access is granted to approved partners so we can support each integration closely and shape the product together. Getting in starts with a short application.
</Info>

## Apply for beta access

The first step is a quick application telling us who you are and what you're building.

## From application to API key

Here's the full journey, from applying to building live:

<Steps>
  <Step title="Apply">
    Submit the [beta registration form](https://docs.google.com/forms/d/e/1FAIpQLSd7tbAVa5rh9Nd3hVlQtQXqt_PDIjta7Dho1YvFAysuSxwf5w/viewform). We review every application.
  </Step>

  <Step title="Application review">
    Our team reviews your application. We'll email you the next step - and may ask for a little more detail.
  </Step>

  <Step title="Discovery call">
    A short call with our team to talk through what you're building, who you'll pay, your expected volume, and your timeline. It's also your chance to ask us anything.
  </Step>

  <Step title="Build in sandbox">
    We securely deliver your **sandbox API key**. Integrate against the test environment and run at least one test payment to confirm everything works end to end. We'll be in close contact throughout.
  </Step>

  <Step title="Final approval">
    When you’re ready, share your integration user interface and payment flow with us for a quick approval.
  </Step>

  <Step title="Go live">
    Once approved, we issue your production API key - and you’re live.
  </Step>
</Steps>

<Note>
  During the beta you work directly with our team, and your feedback shapes what we build next. We keep a regular sync going so you're never stuck.
