Connecting Opayo

The Opayo integration uses API keys to connect. Opayo only allows a single set of API credentials per account, so if you are already using Opayo, find your existing keys rather than generating new ones.

To generate new credentials:

  1. Log in to MyOpayo at live.opayo.eu.elavon.com/mysagepay/login.msp.

    MyOpayo login screen

  2. Go to Settings → Administrator → Opayo API → Create API Credentials. You will need to select the I understand checkbox before you can click the button.

  3. Note your Vendor Name, Integration Key, and Integration Password.

    Tip

    Store these credentials safely — Opayo will not show the Integration Password again.

  4. Select Opayo from the service provider list, then enter the Vendor Name, Integration Key, and Integration Password.

    Add Opayo service provider form

  5. The connection is tested and you are shown a green "Connected to Opayo" message.
