Zelle API Integration

How Salepager Integrates with Zelle — Through Your Bank's API

Zelle doesn't offer a public API. Salepager bridges that gap by connecting to your bank account through secure OAuth 2.0 and FDX-compliant transaction feeds — detecting every Zelle payment, resolving who sent it, and reconciling it to the right invoice automatically.

Why a Banking API Beats Waiting on a Zelle API

Zelle is fast and widely supported — but it has no public API for businesses. Salepager works around that by reading your bank's transaction feed directly. Here is how that banking API approach solves the entire Zelle payment workflow from end to end.

Professional Invoices for Zelle

Send clean, branded invoices with Zelle as the payment method. Your clients know exactly how to pay you — no confusion, no back-and-forth.

Direct Bank-to-Bank Payments

Zelle payments move directly between bank accounts — no intermediary processors, no held funds, no settlement delays. Salepager confirms the deposit the moment it arrives.

Automatic Payment Tracking

Stop checking your bank app and cross-referencing spreadsheets. Salepager detects Zelle payments and updates your invoices automatically.

Works With Your Existing Bank

No need to switch banks or sign up for new payment processors. If your bank supports Zelle, Salepager can connect and start tracking payments.

Know Who Paid — Instantly

Get notified the moment a client's Zelle payment lands. No more wondering if that deposit was for Invoice #47 or #52 — Salepager tells you exactly.

Get Paid Faster

Clients pay quicker when the process is simple. A clear invoice with Zelle instructions means fewer delays, fewer follow-ups, and faster cash flow.

How We Connect to Your Bank — and Why That's All We Need

Salepager leverages the same open banking infrastructure trusted by major fintech platforms. A single secure bank connection gives us the API access required to detect when your clients pay via Zelle and automatically update your invoices.

Secure Connection Architecture
TLS 1.3 AES-256
SOC 2 Type II
FDX Certified
Token-Based
Bank-Grade OAuth 2.0 PKCE
You authenticate directly with your bank through a secure OAuth 2.0 connection. Credentials are exchanged bank-to-bank using PKCE flow. We never see or store your login.
Token-Based Authentication SECURE
Your bank issues a secure access token through an OAuth 2.0 PKCE flow. Credentials are exchanged directly with your bank — we never see or store your login. The token is encrypted end-to-end and revocable anytime from your bank dashboard.
Encrypted FDX Data Stream E2E
Transaction data travels over TLS 1.3 encrypted channels through an FDX-compliant bank API. Data at rest is encrypted with AES-256. Zero plaintext exposure.
Cryptographic Audit Trail SHA-256
Every reconciliation is hashed and logged with a tamper-proof audit trail. Amount, sender, invoice ID, confidence score, and timestamp — all cryptographically signed.
Your data never leaves the encrypted pipeline. No screen scraping. No email parsing. No credential storage.

One Bank Connection. Complete Zelle Invoicing.

When you connect your bank account through Salepager, you authenticate via a secure bank connection — the same open-banking standard used by thousands of financial apps. This single connection is all Salepager needs to confirm when your clients pay your invoices via Zelle. Your login credentials never touch our servers — we receive only an encrypted access token that confirms your identity.

That connection gives Salepager access to your incoming transaction feed — including all Zelle payments — via a bank API built on the FDX standard. When a client pays your invoice via Zelle, we see it immediately: sender name, payment amount, memo text, and precise timestamps.

Our matching engine then connects that Zelle payment to the right invoice — checking the amount, sender identity, memo text, and due dates. The invoice is marked as paid automatically, you get notified, and a complete payment record is logged.

Send invoices. Get paid with Zelle. Everything else is automatic. Real bank data via an FDX-compliant banking API powers the entire invoicing workflow — from payment detection to invoice updates.

What the Bank API Actually Returns

Here is a real example of what Salepager sees when a client pays your invoice via Zelle. This bank data is all we need to confirm the payment and mark your invoice as paid.

GET /accounts/{id}/transactions — FDX v6.0
// Bank API Response — Zelle Payment
{
  "transactionId": "fdx-txn-7e4a9b2c",
  "transactionType": "CREDIT",
  "amount": 3750.00,
  "currency": "USD",
  "postedTimestamp": "2026-02-18T09:14:22Z",
  "description": "Zelle payment from MARTINEZ DESIGN LLC",
  "category": "TRANSFER_IN",
  "paymentNetwork": "ZELLE",
  "counterparty": {
    "name": "Martinez Design LLC",
    "identityToken": "sid_martinez_4kx9"
  },
  "memo": "Nov retainer - INV-2026-1192",
  "status": "POSTED"
}

// Salepager processes this in <2 seconds:
// 1. Detects paymentNetwork: "ZELLE"
// 2. Extracts counterparty identity token
// 3. Parses memo for invoice reference
// 4. Cross-matches amount + sender + due date
// 5. Reconciles → INV-2026-1192 marked PAID

Structured Zelle Metadata

Your bank's enriched transaction data identifies Zelle payments via the paymentNetwork field. Every transaction includes the sender's name, identity token, memo text, exact amount, and posting timestamp — all machine-readable.

Counterparty Identity Resolution

Your bank's counterparties data provides a persistent entity_id for each sender. Salepager uses this to build a sender profile, so even payments without memo text can be matched to the right client.

Memo Parsing + Fuzzy Matching

When senders include invoice references in the memo field, our engine extracts them automatically. When they don't, we fall back to amount correlation, sender history, and due-date proximity to find the right match with confidence scoring.

Zelle API Questions, Answered

No. Zelle does not offer a public API for businesses to track payments, verify transactions, or reconcile invoices. Zelle is a consumer payment network operated by Early Warning Services — it moves money between bank accounts, but it does not expose transaction data to third-party applications.

Salepager fills that gap with a unified Zelle Transactions API. Connect your bank account once, and you get a single endpoint for querying every Zelle payment — incoming and outgoing — with full sender details, amounts, memo text, and timestamps. No emails from your bank, no manual CSV exports, no spreadsheets. Just a clean API that tells you who paid, how much, and which invoice it matches, in real time.

Not from Zelle directly. But Salepager provides a Zelle integration API that gives you programmatic access to every Zelle transaction flowing through your bank account — incoming and outgoing — without relying on Zelle's infrastructure at all.

Here's how it works: you connect your bank account once via a secure, token-based OAuth flow (your credentials never touch our servers). Salepager's API then surfaces a unified transaction feed — every Zelle payment, enriched with counterparty identity, amount, memo, and timestamp. You can query it directly for invoice matching, pipe it into your accounting software, or trigger real-time webhooks when payments land.

The result is a single API that handles Zelle payment detection, invoice reconciliation, and transaction history — all without Zelle ever offering an API themselves. It works with any U.S. bank that supports Zelle, and you don't need to write a line of integration code to get started.

Salepager's Zelle Transactions API gives you a single endpoint for tracking every Zelle payment — incoming and outgoing — in real time. No bank portal logins, no manual reconciliation, no coding required on your end.

Under the hood, every Zelle transaction comes back with structured fields: payment network identifier, counterparty name and identity token, amount, memo text, and a precise timestamp. Salepager's matching engine cross-references this against your open invoices — checking amount, sender identity, memo references, and due dates — and marks the right invoice as paid within seconds. For outgoing payouts, the same API tracks what you sent, to whom, and when it settled.

You don't need to write a single line of code. Send the invoice, and Salepager handles the detection, matching, and status updates. If you want programmatic access — webhooks, CSV exports, or a direct API integration with your accounting stack — it's all available from the same unified endpoint. For most businesses, the dashboard gives you everything you need on day one.
