• Dedicated Customer Success Manager per transaction
• Lower commissions starting from 1% (below 1% for transactions over €1 million)

Integration Methods

Method 1 — Automatic Redirect from Standard Widget

When a user enters an amount of €50,000 or more in the standard widget, the widget automatically shows a Mercuryo PRO notification with a link to the PRO interface. No additional integration is required.

Method 2 — Direct Redirect

Generate a PRO widget URL for a specific user and send it directly.

Steps:

1. Call GET /v1.6/get-otc-id to get a new otc_id.
2. Build the PRO URL with the OTC ID.
3. Send the URL to the user. Mercuryo will contact them to proceed.
