The user interface for configuring a connector call is generic, thus it looks the same for all kinds of underlying types of connectors. Having the same interface for all kinds of connector calls is very convenient. But one drawback of this approach is, that some connectors require fixed parameters to be set, in order to work properly. This section tells you more about these details.
You can declare parameters of Connectors as optional.
When declaring a parameter as non optional, the validation of the call will fail if the parameter is not provided.
Data Type Selector
If you click on the data type field, a selector opens.
| Number | Description |
| 1 | The currently selected data type. |
| 2 | In this filtering list of all data types, you can find manually and automatically built data types. Custom data types are only manual data types. When the dialog opens in an automatically generated connector call, the data types of the connector can also be selected. |
| 3 | Prefilter of base and domain types, structs and collections. |
| 4 | You can always step deeper in the structure to select a data type. |
