To use Perk behind a corporate firewall, you need to make sure customers add these domains and IP addresses to their company’s permitted IPs:

Expense and invoice processing only

If you plan to use Perk to calculate trip and mileage expenses, you need to add https://maps.googleapis.com to your allowlist. Perk uses the Google Maps API to calculate distances based on the locations entered in Perk.

If you use the Spend API (or integrations that rely on the Yokoy API), you need to add this domain to your allowlist: 

• https://api.yokoy.ai

For customers who use SFTP to exchange data via a file-based integration, you need to add this IP to your allowlist:

• sftp://exchange.yokoy.ai
• IPv4: 20.203.148.139

Transactional emails

To prevent emails from being blocked by the company’s mail system, the following domains should be added to a safe list:

• yokoy.ai
• yokoy.io
• travelperk.com
• perk.com
• tripupdates.com
