This is almost always "Yes", as your IT and engineering teams will need a development environment in which they can integrate the software.
The sandbox environment will have similar subdomains to your chosen production environment, but we prepend test- to the beginning of each. E.g. test-portal.yourcompanyname.com, test-api.yourcompanyname
SSL Certificates for Subdomains
SSL certificates are required to secure the API and Portal when configured for white label. Payrix requires the partner to acquire the certificates for each of the subdomains.
Payrix can provide CSRs (certificate signing requests) for each subdomain, which can then be provided to your Certificate Authority of choice to purchase SSL certificates.
Alternatively you can obtain certificates from your Certificate Authority without the optional CSRs, just be sure to include accurate information in the purchase without CSRs as most CAs typically won't refund for typos and mistakes.
