## Natural APIs

A Natural API is a Natural subprogram (cataloged object) that is used for accessing and possibly modifying data or performing services that are not accessible by Natural statements. Natural APIs refer to Natural, a subcomponent or a subproduct.

The utility SYSEXT is used to locate and test Natural Application Programming Interfaces (APIs) contained in the current system library SYSEXT.

For more information, see SYSEXT Utility.

## APIs of Natural Add-On Products

The API of a Natural add-on product is a Natural subprogram (cataloged object) that is used for accessing and possibly modifying data or performing services that are specific to an add-on product or a subcomponent.

The API of a Natural add-on product is supplied in the Natural library and/or system file provided for objects that are specific to a particular Natural add-on product. For instructions on using the API of a Natural add-on product, refer to the documentation of the respective add-on product.

For each API of a Natural add-on product, the utility SYSAPI provides a functional description, one example program, and API-specific keywords.

For more information, see SYSAPI Utility.
