What is IP whitelisting?
IP whitelisting is a security measure that allows only approved IP addresses to connect to Mercury Nexus. When you integrate your EFFI system with Mercury Nexus, you'll need to provide your IP address(es) so our Helpdesk team can authorize the connection.
When do you need to request IP whitelisting?
You'll need to request IP whitelisting when:
You're setting up a new Mercury Nexus integration with EFFI
You're expanding your integration to additional IP addresses or servers
Your IP address changes and you need to update your existing whitelist
Note: If you already have an EFFI integration set up, your IP may already be whitelisted. Check with your Partnership Manager before submitting a new request.
Submitting your IP whitelisting request
To request IP whitelisting, provide your Partnership Manager or the Helpdesk with:
Your IP address(es) that will connect to Mercury Nexus
Any relevant system or server details
Email your request to [email protected]
Understanding the fee
All new IP whitelisting requests incur a one-time fee of $300.
This fee is required for the service and the accounts team will invoice you directly
What happens after you submit
Once your request is received:
The Helpdesk passes your request to the accounts team to generate an invoice
The Helpdesk team processes your whitelisting request
Your IP address(es) are added to the Mercury Nexus whitelist
You'll receive confirmation when your integration is active
Important: You'll be invoiced $300 for this service. Please ensure you settle the invoice as requested.
Timeline
IP whitelisting requests typically take 2–3 business days from payment confirmation. The exact timeline may vary depending on workload.
Additional information
If your circumstances change—such as a new IP address or additional servers—submit a new whitelisting request following the same process.
