Firstparty will serve assets and collect Events from a first-party domain you configure. This maximizes reliability and accuracy when collecting Events from a website by ensuring the data collection domain matches the domain of the site being visited.
Additionally, using a matching first-party domain reduces the risk of data collection being restricted by browser settings or ad blockers.
Security
DNS Records
Firstparty will provide a unique CNAME location for you to add to a subdomain (typically fp) of your website's domain. This CNAME destination is a specific subdomain of firstpartydns.com, which is exclusively used to proxy traffic to securely proxy traffic to Firstparty infrastructure around the world.
For example, if your website is widgetparty.com, Firstparty will ask you to configure a DNS CNAME record with host name fp having a value of widgetpartycom.clients.firstpartydns.com.
Every Domain you configure in Firstparty will receive its own unique CNAME value.
SSL
Firstparty automatically handles generation, maintenance, and renewal of SSL certificates for all Domains configured in your Workspace.
Firstparty will attempt to verify that the requested DNS record has propagated appropriately after you save the Domain in your Workspace. Once this is verified, Firstparty will provision a unique SSL certificate from LetsEncrypt for the specific subdomain pointed at Firstparty.
Using the example from above, if your website is widgetparty.com, we'll create an SSL certificate for fp.widgetparty.com.
SSL certificates are SSLv3 and use the SHA-256 with RSA Encryption signature algorithm. Certificates are typically valid for 90 days and are automatically renewed as needed.
