You can delete user-defined REST API macros but not system-defined macros. Deleting a REST API macro deletes it for all your devices. Macros are not specific to a particular device.
- Open the Devices & Services page.
- Select an FTD device and in Device Actions on the right, click API Tool.
- Select the user-defined REST API macro you want to delete.
- Click the trash can icon in the REST API macro label.
- Confirm you want to remove the REST API macro.
