Hi

1) Design your data model - tabletypes, structures, fields - for all needed collections and resources

2) create an API class to access all the relevant collections/resources with the desired methods. Also authentication, checks and mapping (OData) data model <> external API should be done here

3) generate the Gateway services based on you data model

4) Implement all needed methods in the DPC_EXT class: e.g. ..._GET_ENTITYSET, ..._CREATE_ENTITY, ..._DELETE_ENTITY, ..._UPDATE_ENTITY and call the corresponding API class methods
