Moov API Integration Services for Embedded Payments in the USA 

Embedded payments become difficult when a product tries to manage onboarding, payment methods, money movement, fees, refunds and reconciliation as separate features. Customers experience one flow, so the underlying systems need to behave like one system too.

FintegrationFS provides Moov API integration services for US SaaS platforms, marketplaces, fintech startups and vertical software companies. We help teams build account, source, transfer, card and webhook workflows using the current Moov API version enabled for their program.

Moov API for Embedded Payments and Money Movement

Moov provides APIs and components for accounts, capabilities, bank accounts, cards, wallets, transfers and related payment operations. Server-side integrations can use API credentials, while client-side experiences can use scoped OAuth tokens and Moov.js so sensitive information goes directly to Moov.

The best approach depends on the data your server should handle, the customer experience, compliance responsibilities and the payment methods involved.

Moov API Architecture for a Platform Payment Flow

45. Create or map the platform and user accounts required by the approved program.

46. Collect profile and representative data through server-side or client-side components.

47. Request and monitor the capabilities needed for the intended action.

48. Create or link eligible payment methods.

49. Submit transfers from the correct source to destination with a unique idempotency key.

50. Process signed webhooks and update the internal ledger or order state.

51. Reconcile transfer, refund, fee and settlement records against internal obligations.

Use an explicit API version header. Moov publishes versioned APIs and may default older behavior when the header is missing. Pinning and testing the version reduces unexpected production changes.

Technical Code Example: Create a Moov Transfer 

import crypto from "node:crypto"; 
 
const ACCOUNT_ID = process.env.MOOV_PLATFORM_ACCOUNT_ID; 
const VERSION = "v2026.07.00"; 
 
export async function createMoovTransfer({ sourceId, destinationId, cents }) { 
  const credentials = Buffer.from( 
    `${process.env.MOOV_PUBLIC_KEY}:${process.env.MOOV_PRIVATE_KEY}` 
  ).toString("base64"); 
 
  const response = await fetch( 
    `https://api.moov.io/accounts/${ACCOUNT_ID}/transfers`, 
    { 
      method: "POST", 
      headers: { 
        Authorization: `Basic ${credentials}`, 
        "Content-Type": "application/json", 
        "X-Moov-Version": VERSION, 
        "X-Idempotency-Key": crypto.randomUUID() 
      }, 
      body: JSON.stringify({ 
        source: { paymentMethodID: sourceId }, 
        destination: { paymentMethodID: destinationId }, 
        amount: { currency: "USD", value: cents }, 
        description: "Platform payment" 
      }) 
    } 
  ); 
 
  if (!response.ok) { 
    const body = await response.text(); 
    throw new Error(`Moov transfer failed: ${response.status} ${body}`); 
  } 
 
  return response.json(); 
} 

Payment State, Webhooks and Reconciliation

Transfers can move through multiple states. Your user interface should explain whether money is pending, completed, failed or returned without exposing provider jargon. Internally, preserve the provider state, event ID and timestamps for investigation.

• Verify webhook signatures before processing

• Store and deduplicate every event ID

• Do not assume event order

• Fetch the latest resource when state is ambiguous

• Separate customer-facing status from accounting state

• Create alerts for stuck transfers and webhook delivery failures

• Reconcile fees and refunds, not only principal amounts

Frequently Asked Questions

What can the Moov API support?

Depending on the program and enabled capabilities, Moov can support account onboarding, payment methods, transfers, wallets, card operations, refunds, disputes and related embedded-payment workflows.

Should we use server-side or client-side Moov authentication?

Use server-side credentials when the trusted backend is handling the API. Client-side experiences should use scoped tokens and approved components so private credentials are never exposed.

Why is the X-Moov-Version header important?

It pins the integration to an expected API version. This makes testing and controlled upgrades easier.

How should Moov webhooks be processed?

Verify signatures, persist events, deduplicate them, process through a queue and refresh the current resource state when necessary.

Does FintegrationFS provide payment processing?

No. Moov provides the approved platform services. FintegrationFS provides independent software architecture and integration services.
