Orbitz doesn’t provide its own API. This OTA is a brand of Expedia Group. So, look for a connection with them.
If you’re an OTA, TMC, metasearch, or other travel provider, Expedia has its Rapid API. It lets you retrieve hotel data and booking rooms. To get access to Rapid, you first have to apply for a partnership with Expedia. If they approve you as a partner, you can start testing the API. Here’s their Expedia Partner Solutions page.
Before going live, you must make sure that you comply with their requirements.
If you’re a hotel, use Expedia Connectivity to hook your property to all Expedia products. Check their API documentation. The API manages bookings and sends updates about your property, rates, availability, etc. To become their lodging partner, first, register your property by joining Expedia Partner Central.
