This project is really very exciting.
I designed and implemented a TYPO3 extension here according to customer requirements. This TYPO3 extension is used to sell storage rooms based on the MyPlace model.
The storage room data is stored centrally in another system. This data is accessed via REST API.
The storage rooms are stored in a relational database model, so that a connection to the REST API does not have to be established with every website call. This speeds up loading times and protects against REST API failures.
The data is compared directly before the order and continuously.
The ordering process is handled by an external service provider: Mollie.
The programming is done in an Extbase extension with several frontend plugins.
