To set up a custom store domain, follow these steps:

2. Provide your company details.

Following your discussion with our Sales team, send the following company information to our Merchant Support team. This information is used by 2Checkout to generate a Certificate Signing Request (CSR) on your behalf, as the certificate will be hosted on our server. Make sure that the data sent is correct, as it will be included in the CSR file. The information will be validated by the Certificate Authority before the SSL certificate is sold to you.

  • Certificates shall be purchased from Certificate Authorities trusted by your customer’s browsers.   Such authorities are commonly referred to as “Public” Authorities. and some examples are listed  here.
  • Certificates shall contain the full hostname of the target, such as  “Wildcard” certificates are not supported.

3. 2Checkout generates private and public keys and the CSR.

2Checkout uses the information mentioned above to generate the private and public keys as well as the Certificate Signing Request (CSR) necessary to acquire a Secure Sockets Layer (SSL) Certificate from a Certificate Authority. The CSR file generated by 2Checkout will be e-mailed to you by our Vendor Support team, together with instructions on your next steps.

SSL certificates act as a method of securing data transmissions, including sensitive details such as payment information.
While the public key and CSR are shared with you, the private key will be stored only inside 2Checkout’s secure environment, ensuring that SSL security cannot be compromised. 2Checkout ongoing investment in security is reflected by the PCI DSS Certification received yearly.

2Checkout does not accept and will not use SSL certificates purchased based on private/public keys and CSRs you generate yourself or which have been previously used. Custom domains and associated SSL certificates can be used only if 2Checkout is the sole keeper of private keys.

4. Purchase the SSL certificate using the 2Checkout generated CSR.

Use the CSR file provided by 2Checkout to acquire an SSL certificate from your preferred CA. If at any time during the purchase process you’re asked about the server platform type, choose Apache.
When purchasing an SSL certificate you are responsible for:

  • Deciding which Certificate Authority to buy it from. We recommend one of the following providers:
  • Choosing the type of SSL certificate:
    • Extended Validation (EV) SSL Certificate – complex and extensive vetting of your company per the EV Guidelines ratified by the CA/Browser forum in 2007. This is the only type of SSL certificate providing visual feedback to browser users by turning the address bar green for valid EV SSL certificates or red for untrustworthy sites.
    • Organization Validation (OV) SSL Certificate – the CA checks to see if your company is a legitimate business by verifying your credentials and if you have the right to use the domain name.
    • Domain Validation (DV) SSL Certificate – only name and contact information are checked to see if you have the right to use the domain name.

5. Send the SSL certificate to 2Checkout

Send the SSL certificate by email to 2Checkout will finalize the setup of the custom domain and install the certificate.
