HQ Rental is an ApexGenius private-preview connection. It uses an HQ tenant token and user token instead of OAuth.

​
Enable the HQ API first

HQ Rental documents API access for eligible Professional or Enterprise accounts. An HQ administrator must enable the integration before the tokens are useful:
  1. Open Settings → Car Rental → Integrations.
  2. Open Other Integrations.
  3. Enable Custom Integration.
  4. Confirm the regional API base URL assigned to the tenant.
HQ says enabling this creates a Custom Integration user and emails the administrator the integration-user password, encoded authorization token, regional base URL, and a Postman collection. Keep that email private. If the option is missing, ask HQ Rental support to confirm the tenant’s plan and API access.
Tenant setup is not a public app submission.For one HQ tenant, the public setup is the plan check and administrator enablement above. HQ’s public API docs do not describe an app marketplace review. If ApexGenius will be offered as a commercial integration across unrelated HQ customers, confirm partner, redistribution, branding, and support requirements with HQ Rental separately before calling it an approved integration.

​
What you need

Ask an HQ administrator for these four values: HQ provides the applicable regional base URL when API access is enabled. The encoded authorization token in HQ’s email represents the tenant-token and user-token pair. ApexGenius currently asks for those two source tokens separately so the private gateway can construct the required Basic authorization value server-side. Do not paste the integration-user password or the Postman collection into ApexGenius.
Use a dedicated HQ user.Create or choose an HQ user whose permissions match the work you want the AI client to perform. The user token carries that user’s HQ access boundary.

​
Connect the tenant

  1. In ApexGenius, open Connections.
  2. Select HQ Rental.
  3. Choose Connect HQ Rental.
  4. Enter the tenant label and API region.
  5. Paste the tenant token and user token.
  6. Choose Verify and connect.
ApexGenius tests a safe location search before it stores the credential pair. If verification fails, confirm the region, confirm that both tokens are current, and confirm that the HQ API is enabled for the tenant.

​
What ApexGenius stores

The browser sends the two tokens to the authenticated ApexGenius backend. The backend stores the composite credential through the encrypted credential-vault path and returns only the connection identifier. The connection screen does not display either token after setup. Disconnect the HQ Rental card to remove the active ApexGenius connection. Rotate or revoke the source tokens in HQ if you believe either token has been exposed.

​
Private gateway prerequisite

The ApexGenius HQ Rental sidecar must also be configured and healthy. This is an ApexGenius deployment requirement, not a field the customer pastes into the connection form. If the screen says Gateway setup required, contact us before retrying the connection.
