What Integrations Are Possible with Converge Pay?
Converge Pay is designed to work as the payment layer inside a larger technology stack. Rather than replacing your existing tools, it connects to them so that transaction data flows automatically between systems. Common integration categories include e-commerce shopping carts, point-of-sale terminals, accounting and ERP software, property-management systems, and fully custom applications built on the Converge API.
The scope of what you can connect depends on the integration method you choose. Elavon provides a hosted payment page for the simplest setups, a direct-post model for merchants who want more control over the checkout experience, and a full RESTful API for developers building bespoke workflows. If you are not sure which path suits your business, our overview of Converge Pay explains where the gateway sits in the payment chain.
Retrieving Your SSL Credentials
Every integration starts with credentials. You will need three values from your Converge account: the SSL Merchant ID (your Account ID), an API-dedicated User ID, and the corresponding PIN. To find them, visit the Converge Pay Login page, sign in, navigate to the account settings area, and look for the section labeled "Terminal Credentials" or "API Credentials."
We recommend creating a dedicated User ID for each integration rather than sharing your personal login. This keeps audit trails clean and lets you revoke access to a single integration without affecting others. For a walkthrough of user management, see the sub-accounts section in our features article.
Sandbox vs. Production
Elavon provides a sandbox environment for testing. Before sending live transactions, configure your integration with sandbox credentials to verify that authorizations, voids, and refunds all behave as expected. Once testing is complete, swap in your production credentials and go live.
Hospitality and POS Setup
Hotels, restaurants, and retail locations often pair Converge with a physical card terminal or a POS application. The terminal handles the card-present swipe or tap, while Converge routes the authorization to Elavon's processing network and records the transaction in your online dashboard.
For hospitality businesses, the auth-and-capture workflow is essential. A hotel front desk authorizes a card at check-in for the estimated stay amount, then captures the final total at checkout. Converge supports incremental authorizations, so you can increase the hold if the guest adds room-service charges. Restaurants follow a similar pattern: authorize the pre-tip amount, then capture the adjusted total after the tip is added.
Accounting Software Setup
Keeping your books in sync with your payment data saves hours of manual reconciliation. Several accounting platforms offer built-in connectors for Converge, or you can use a middleware service to map transactions to your chart of accounts automatically.
The typical flow works like this: Converge settles a batch, the connector pulls the settlement data via the API, and it creates corresponding entries in your accounting ledger. Sales, refunds, fees, and chargebacks each map to a separate account, giving you a clear picture of net revenue without spreadsheet gymnastics.
If your accounting tool does not have a native Converge connector, you can export batch reports as CSV files from the dashboard and import them manually. For businesses processing a high volume of transactions, the API route is far more efficient. Learn more about which businesses benefit most from automation in our small-business guide.
Custom API Integrations
For developers, the Converge API opens the door to fully custom payment flows. You can build a checkout experience that matches your brand exactly, store tokens for repeat customers, set up webhooks that notify your server when a transaction settles or a chargeback is filed, and pull reporting data into your own analytics stack.
Hosted Payment Page
The simplest integration approach is the hosted payment page. You redirect the customer to a payment form hosted on Elavon's servers. After the customer submits their card details, Converge processes the payment and redirects the customer back to your site with a transaction result. Because the card data never touches your server, your PCI scope is minimal.
Direct Post
In a direct-post integration, your checkout form submits card details directly to the Converge endpoint. This gives you full control over the look and feel of the payment page while still offloading card processing to Elavon. You will need to meet additional PCI requirements because your HTML handles raw card numbers, even though they are transmitted straight to the gateway.
Token-Based Recurring Payments
If your application bills customers on a schedule, you can tokenize the card on the first transaction and reuse the token for subsequent charges. Converge stores the token securely, so your database only holds a reference string. This approach is popular with subscription services, membership organizations, and installment-based billing models.
To begin building your integration, sign in through the Converge Pay Login page, generate your API credentials, and consult Elavon's developer documentation for endpoint details and code samples.
