Travel development, main stones?

Question

API

Hello.
There are a number of questions, I am writing more here in order to find a person who is well versed in this for further consultation.
1. Information providers, what are the main pitfalls and where to find a complete list of GDS systems.
2. Did I understand correctly that the bundle works like this. QPX (we look and book), GDS (we buy what we have already chosen) a follow-up question. Data can be different?
3. Do I need to connect only one GDS, or all existing largest ones?
4. Is it possible to temporarily get by with other apis, for example, take booking or aviasales, take information from it without extra charge, display it temporarily in its interface, and then rewrite the module under GDS?

Answer 1

1. GDS relevant for Russia: Amadeus, Saber, Galileo, Sirena, Gabriel - the main pitfalls are paid connection, your company must be an IATA accredited agency, you must have very good knowledge of the subject area.
2. GDS has a full cycle (search, booking, checkout), why use something else?
3. Usually they connect one BSP-shnuyu (Amadeus, Galileo, Saber) + Russian (Siren)
4. In my opinion, extra work.
PS If you are interested, write, we have an API to which all GDS have already been added, and we give you a uniform API + there are partner agencies ready to provide their GDS gateways if you do not want to buy your own.
