First-Party Cookie Settings
If you are switching to the iframe-based subdomain, it is recommended to configure the first-party cookie settings before setting up the subdomain.
If the subdomain is set up first and the first-party cookie setting is not yet complete, a popup blocker may be triggered.
Where to configure
Brand Management Screen → Admin Settings → First-Party Cookies
The First-Party Cookie Settings screen will open.
Registering an API Domain
Once you select whether or not you have an SSL certificate and save the domain, it will be fixed to that path. Please be careful.
If you have an SSL server certificate
Enter the desired API domain URL, along with the SSL certificate, SSL private key, and SSL chain file (intermediate certificate).
Example API domain URL: api.tripla-hotel.com
※The prefix does not need to be api.—you may set it freely.
However, please note that the same URL cannot be used for both “Subdomain URL registration” and “First-party cookie URL registration.”
Clicking [Save] will change the Status displayed at the top of the screen.
Title | Status |
| Start | No settings have been configured yet. |
| Checking DNS for SSL Certificate | DNS verification for issuing the SSL certificate is in progress. |
| erifying SSL Certificate Settings | SSL certificate settings are being verified. |
| Verifying Load Balancer Settings | Load balancer settings are being verified. |
| Complete | Verification is complete. ※Once verification is complete, [Test] will no longer be selectable. |
You can click [Test] to check the current progress.
If you do not have an SSL server certificate
Enter the desired API domain URL.
Example API domain URL: api.tripla-hotel.com
※You are not limited to using api.—the domain can be freely customized.
However, please note that the same URL cannot be used for both "Subdomain URL registration" and "First-party cookie URL registration."
Click [Save] to update the “Start” status displayed at the top of the screen.
Title | Status |

To proceed with verification, please update the CNAME record in your DNS provider.
DNS Record Setup – “Verification CNAME Record”
This verification CNAME record is only valid for 72 hours.
Please complete the CNAME record setup in your DNS provider’s management screen within this timeframe.
Enter the displayed verification CNAME record information into your DNS settings screen (provided by your DNS hosting service).
Ex: DNS record settings screen
Item | Setting |
| Update the CNAME record in your DNS provider for verification (Host Name) | 1st line of the verification CNAME record |
| Type (TYPE) | CNAME |
| TTL (Time to Live / Priority) | 60 |
| CNAME Target (VALUE / Destination) | 2nd line of the verification CNAME record (CNAME Target) |
Verification CNAME Record – 1st Line:
※In your DNS provider’s DNS record settings screen, the leading underscore ( _ ) cannot be omitted.
If the input is not accepted, the trailing period ( . ) can be omitted.
※Also, depending on your DNS provider, part of the name (host name) may be pre-filled by default.
In that case, make sure to adjust your input to match the 1st line of the verification CNAME record displayed in the tripla management screen.
Verification CNAME Record – 2nd Line (CNAME Target):
※If your DNS provider’s record settings screen does not accept the input, you may omit both the leading underscore ( _ ) and the trailing period ( . ).
After completing the setup, the screen will change to [Checking DNS for SSL Certificate Issuance].
Clicking [Test] allows you to check the current status of the setup.
Registering the IP Address for A Record
Please register the provided IP address under the appropriate A Record in your DNS settings.
Once configured, click [Test], and based on the status, the following tabs may appear:
Title |
| The IP address for the A Record is not correctly set in DNS. |
| The CNAME Record is not correctly set in DNS. |
| The CNAME Record has expired. Please click Reset to issue a new record. |
With this, all settings are complete.
