How to Go Live on the Open Payments Stack in 4 Steps

Legacy payment processors love friction. They want you to hop on a 30-minute "discovery call," sign a stack of NDAs just to look at their API docs, and wait weeks for a risk engineering team to decide if your business is "too complex" for them.

If you are building in high-velocity, modern verticals like prediction markets, AI startups with usage-based billing, stablecoin fintechs, or creator platforms you don’t have time for the legacy crawl.

At Credible, we built the Open Payments Stack for businesses traditional gateways won’t touch. We combined local fiat rails (UPI, Pix, ACH, SEPA) with a DeFi liquidity orchestration layer that fronts the float, turning agonizing T+3 settlement delays into instant, T+0 payouts in USDC, USDT, USD, EUR, or GBP.

Best of all? You can bypass the corporate gatekeeping. Here is exactly how you go from zero to live transactions in just four steps.

Step 1: Self-Onboard (Zero Commitment)

We don't hide our platform behind a form. You can create an account, connect your business details, and completely preview the product before committing a single line of production code. It’s built to let you explore the dashboard and infrastructure first.

Step 2: Complete Async KYB

No one wants to schedule an appointment just to verify their corporate identity. Our modern, asynchronous Know-Your-Business (KYB) process is entirely self-serve. Upload your compliance documents, let our system review them in the background, and move on with your day while we handle the verification.

Step 3: Consume the APIs

Once verified, you are ready to ship. You don't need permission to read our documentation. Authenticate your keys and start hitting our core REST endpoints:

Pay-in: Accept global cards, local rails, and stablecoins.

Pay-out: Trigger instant global payouts backed by stablecoin liquidity.

Ledger & Webhooks: Track on-chain reconciliation and settlement stats in real time.

Step 4: Spin Up a Prefunding Pool

This is where the magic happens. To fund your settlements entirely on your terms, you can open a permissionless, programmatic prefunding pool. It gives you absolute, transparent control over your capital flows, or you can tap into our liquidity pools (which earn DeFi backers 16% APY) to scale your transaction volume effortlessly.

Stop Waiting, Start Building

Traditional processors quietly decline the businesses they don't understand because they can't model for high-velocity deposits or cross-border microtransactions. We engineered our stack specifically for those edge cases.

With over $500M+ in payments processed and 24/7 API uptime, the infrastructure is ready. No sales pitches required.
