Many API endpoints allow you to submit the Alternate Key ID for a record. The Alternate Key ID (also referred to as the "Unique Identifier") is a user-defined field that uniquely defines a record in a table. The Alternate Key ID can be based on a single field, or on a combination of more than one field.
By default, the Alternate Key ID is an "Inactive" field, meaning it's not displayed within the Record Lookup screen. Before you can look up the value in this field, you first need to make sure that the field is "Active."
Navigate to the Table screen for the desired table.
Expand the "Inactive Fields" section to see if the Alternate Key ID is listed there. The default name of the field is "ak_<tablename>." If the Alternate Key ID field is displayed within this section, click the change button ("X" icon) to the right of the field name. The system moves this field from the "Inactive Fields" section up to the "Active Fields" section.
In the Tool Ribbon, click Edit > Actions > Save.
Now that the Alternate Key ID is an "Active Field," you'll be able to see it on the Record Lookup screen.
Navigate to the Record Lookup screen, and search for the desired record.
Within the search results, click "Edit" next to the desired record. The system opens a new "Database Record" tab within the Top Navigation Panel. By default, the "Record Details" tab is selected. The Alternate Key ID field will now be displayed on this screen.
