Galileo is one of three GDSs along with Apollo and Worldspan that comprise Travelport GDS. Travelport has a pretty straightforward workflow to get started with product.

1. Request trial access to Galileo APIs and submit a form on Travelport’s website. There, you’ll have to choose your preferred GDS from the three (Galileo in your case). This is free, and you will receive a key to Galileo in a few minutes. Here’s a link to documentation to help you.
2. When you’re done with testing, contact an Account Manager from your profile or Travelport itself, and they will supply you with authorization.
3. After you are authorized, contract finalization and certification will start. This is called the Pre-Production stage. Travelport asks you to complete a Universal API Requirements Questionnaire [.docx] to evaluate your capacity needs. After completion, you should request a sales representative call to review your questionnaire and finalize certification.
4. When you receive your API certification, you enter the Production system. Make sure your developers and systems comply with Travelport’s requirements. You will receive further instructions from your account manager.
