The List Services API provides a comprehensive list of all supported services available within the system. This list can be used to create customized presets of services based on different use cases or user groups, such as business-to-business (B2B) services, business-to-consumer (B2C) services, streaming services, and more. By creating a customization entity that contains a specific list of services, you can tailor the services displayed by the Sunlight Connect SDK to meet the unique needs of your users. This API is a valuable tool for enhancing the user experience by offering relevant and curated service options.
