TravelgateX is a bridge between the systems of Buyers and Sellers and committed to providing 100% transparency on all the connections. We aim to ensure that our Partners always receive the raw information as provided by the Seller without any modification.
In this case, through the Board List query, you'll be receiving the Seller's native room codes, so you can map them along with the Seller if needed.
Please note that If you are using Hotel-X API, you can upload your own mapping files to our FTP (credentials must be provided by our Customer Care team), and we will use your board codes in the booking flow. To upload your codes to the FTP, please follow the guide described here
*Mapping should be done either internally or externally on your side, we don't perform mappings for our Partners.
