Requirements
WordPress and PHP
| Requirement | Details |
|---|---|
| WordPress | 6.4 or newer (see plugin readme for “Tested up to”). |
| PHP | 8.0 or newer. |
Your hosting must allow outbound HTTPS requests so the plugin can reach your booking provider’s API.
Administrator access
All Booking Engine screens need a user who can manage settings—normally an Administrator. If you use a role editor, ensure your editors have access where appropriate.
What you need from Kross (typical setup)
Before configuring Connection and Checkout & fallback, gather:
| Item | Used for |
|---|---|
| Hotel ID | Tells the API which property to query. |
| API key | Secret key paired with your integration. |
| API username | Login identity for API token exchange (your provider may label this “API user”). |
| API password | Password for that API user. |
| Booking engine base URL | The customer-facing website where guests finish the reservation after clicking Continue / Book on your WordPress site (configured separately from API credentials). |
Exact labels in the Kross dashboard may differ; match them to the fields on Booking Engine → Connection and Booking Engine → Checkout & fallback.
