Start a transaction
Are you using a device?
- Make sure you review our steps on including additional fields and methods when integrating a payment device below:
- Simple Checkout Form- Modal- Device
- Custom Checkout Form- Form Fields- Device
- Embedded Payment Form- URL Page- Device
- Best Practices:
- Are you passing us AVS? One of the easiest ways to protect your merchants from chargebacks is by reviewing your input fields and ensuring you are passing the billing_address and billing_postal_code information to merchants.
- A unique UUID is a happy UUID: please generate a unique UUID each time you start a new sale, even if the last one didn’t finish/failed/etc.
Your goal within this step is to call the emergepay interface and use it to accept the payment card information.
In this step, you will want to guarantee you are receiving results on your payments by using our postback or retrieval methods. Receiving reliable results is key for any integration, you can Poll us directly, or have us Post them to a URL of your choice.
Decide on an account and get production credentials from your Integration Specialist.
