A customer who has already invested in and is familiar with TYPO3 for their primary websites, and whose employees are trained in TYPO3, desires to set up a store with SAP CC. This prompted us to consider the integration aspect.

Comparable scenarios

• Customers who have already developed their main websites using different front-end frameworks can effortlessly integrate a store. They have the option to maintain their existing front-end modules while establishing a headless site with SAP, leveraging TYPO3 as its headless CMS. 
• Customers who desire to utilize comprehensive CMS functionality alongside their store capability require a robust CMS, rather than opting for a complex out-of-the-box CMS provided by SAP Commerce.

As outlined in the diagram above, we facilitated communication from SAP CC to TYPO3 through the OCC layer REST API, extending from SAP CC to our custom TYPO3 extension, secured with OAuth. This approach provides an additional advantage in tailoring the solution for TYPO3 users' configuration needs.

For example, the TYPO3 admin can customize the following for a search result page:

• The number of products displayed during the initial load.
• The presentation format, whether as a list or grid.
• And additional configurations.

Overview

We adhered to the high-level architecture, enabling us to seamlessly integrate TYPO3 CMS into the SAP CC Store. This integration means that SAP CC manages all aspects of:

In the meantime, TYPO3 oversees:
