How to Add a Bank Feed Connection in LedgerSync

Overview

Adding a bank feed connection in LedgerSync allows you to aggregate bank statements, transactions, and check images for a client. LedgerSync offers five connection types. This article explains when to use each one and how to add the connection.

Steps to Add a Bank Connection

1. Log into the LedgerSync application
2. Select the client from the left panel
3. Click Add Bank Connection (top-right corner)
4. Choose the appropriate connection type from the options below
5. Search for the bank by name and follow the prompts

Connection Types

Option 1 — Mastercard API (Statements & Transactions)

Use this for most banks. The Mastercard API retrieves bank statements and/or transactions for institutions listed in the Mastercard Open Finance Supported Institutions directory.

• Search your bank and look for green checkmarks under SA (statements) and TA (transactions)
• If the bank supports only one of the two, the connection still works for what is available

Option 2 — MX Connection

MX is LedgerSync’s second full bank data aggregator — not a beta feature. Use MX when:

• Your bank is not listed in the Mastercard directory
• You want an alternative aggregator for better coverage or reliability

MX supports both transaction and statement aggregation for covered institutions, handles MFA prompts the same way as Mastercard, and includes nightly transaction refresh and broken-connection fix notifications. See: MX Bank Connection — Overview, Setup, and FAQ

Option 3 — Premium Bank Connections

Use Premium connections for:

• Check and deposit image fetching — the primary use case for Premium connections
• Accessing statements for banks not covered by Mastercard or MX

Premium connections work best when the LedgerSync Desktop App (LSDA) is running. See: LedgerSync Desktop App — Download & Install Guide

You can now invite clients to connect via Premium Bank Connections directly from the Communication Center — alongside the existing Mastercard and MX options. This is useful for Capital One Premium connections and other banks where Premium is required.

Option 4 — Capital One Statements

A custom LedgerSync connection built specifically for Capital One bank statements. Note: Capital One transactions are still pulled through Option 1 (Mastercard API), not this connection. This option covers statement PDFs only.

Option 5 — Mercury (Direct API)

For clients who bank with Mercury. LedgerSync has a direct API connection with Mercury Bank, providing statements, balances, and transactions with virtually no connection breakages. See: Mercury Bank — How to Connect to LedgerSync

Viewing the Connection Type After Adding

After a bank connection is added, you can see which aggregator (Mastercard, MX, or Premium) it uses directly from the Client Summary tab. Each connection is labeled with its source so you always know how the data is being pulled without needing to click into each account.

Important Notes

• Some banks require additional authentication (MFA, OTP codes) during setup — follow the on-screen prompts
• If a connection requires MFA at refresh time, you or the client will be prompted in the same way
• Contact Support if you experience issues connecting a specific bank: support@ledgersync.com
