The two reasons that explain why Integration Procedures are recommended as the first choice of data sources for FlexCards and OmniScripts are: they future-proof your front-end design and they combine multiple actions into a single server call. An Integration Procedure can abstract the data source from the front-end design, making it easier to change or update the data source without affecting the FlexCard or OmniScript. An Integration Procedure can also execute multiple DataRaptor actions, such as Extract, Transform, and Load, and also invoke REST or SOAP services in one call, reducing the number of requests and processing time
