What is the difference between PULL and PUSH Sellers?

In this article, you will be explained the main difference between PULL and PUSH integration.

Let's start at the start: what's an XML integration?

An XML integration is basically a connector that acts as a "translator" between the systems of customers and suppliers, allowing different formats or programming languages ​​(usually XML) to be compatible. This way the information from a hotel provider, a Rent a Car, an airline, a railway company, or a shipping company is available on the website of an online travel agency, even if they have the databases information differently structured.

PULL Connection

PULL integrations, like PUSH integrations, always involves two agents: a seller (supplier) and Buyer. The PULL integration is a two-way system by which Buyers, such as OTAs (online travel agencies), tour operators, etc send requests for Availability to TravelgateX (TGX for short 😀) and as soon as we receive this request, we query the suppliers and they respond instantly.

The static information (Hotel List, Geographic Tree, Destination Tree, Room List…) will be downloaded as well from the Seller's API. The quantity and quality of this information will depend on what the PULL Seller provides to us. The Hotel/Room/Destination codes… obtained/returned from the Seller will be the ones the client will receive.

Static Information is refreshed in our system every 2 weeks (we can force a refresh if required -just open a ticket to our Customer Care Team). In regards to pictures, if the Seller provides this information, we will return it. Normally, they use to include image URLs.

Using a PULL Connection, you as a client won’t need to do any additional tasks on TGX, like for example building the Hotel Structure, which is something that it’s done on our Inventory Extranet only for PUSH Connections.

PULL Connectivity Advantages

  1. Real Time communication between clients and suppliers
  2. Technically easier to develop.

PULL Connectivity  Disadvantages

  1. These integrations need to be able to support higher traffic so they require a higher system investment than PUSH integrations.


PUSH Connection

The PUSH Connection, as its name says, it’s a connection where the Channel Managers PUSH their product to TGX Database/System.

When a PUSH Connection is done, the client (accordingly to what they agreed with the hotels) will build the Hotel Setup on our Inventory Extranet. The Hotel Setup is the structure of the hotel: Hotel->Rate->Rooms (and Offers/Derived Rates).

Once the client has finished the Hotel Setup, they have to inform the Channel Manager so they can PUSH the Availability for them. As soon as the Channel Manager PUSH their product to this connection in our System, the product will be immediately processed and offered to the client. The client and the Channel Manager/Hotels should be always in touch in order to be aware of Hotel Structure Changes (like modifications/new rates/rooms).

In regards to the Static Information, this information is created and stored directly at TGX System, which means that the Hotel Codes and Room Codes will be from TGX system (and not from the Supplier as the PULL Connections), and they will be the same for any Channel Manager PUSH Connected in TGX. For PUSH Connections, content like images, hotel descriptions, amenities…is not provided.

PUSH Connectivity Advantages

  1. Suppliers don't have to support so much traffic so they don't require such high systems inversion.

PUSH Connectivity  Disadvantages

  1. No activity occurs in real time as the supplier, once they update the availability, doesn't communicate with the client until the available products are sold.   
  2. They are much more complex than PULL therefore require more development time.


Please, remember that TGX acts as a bypass: we send the Buyer the information received from the Seller regardless if it’s PUSH or PULL. We do not do mappings for clients, but we offer our Hotel-X Buyers the possibility of loading their hotel/board/room mappings directly to an FTP in our system. 

Also important to remember is that TGX does not provide a Calendar Method. In case the client needs a Calendar of Availability, they will have to scan the Sellers by sending the necessary Avail Queries for different dates and hotels, and then build this Calendar with the information received.
