We have a saas that our customers use to create travel experiences and receive bookings.
We want to let them expose those experiences and all the booking process on their website in a "white label" way, so the user even don't know it's using an external system to complete that booking (choose experience -> view images and details -> select date and time -> check availability -> insert booking details -> pay in advance)
We are using Yii2 / PHP 7.4 / MySql on backend side. On Yii2 it's easy to create API and webservices, we'll take care of it. We just need the structure of a robust JS script to load those contents and inject theme on third party website.
It will be really important if you can attach to your proposal a link to test a script like the one I'm looking for.
It would be great if you send to me in chat a js link to embed to load dynamic contents as per my request
