Hi @kienl, it’s a unique identifier (uid) auto-generated by the KoboToolbox system to match and track the export setting.
For e.g. here is my first export setting:
So if you look at the API, you should see that the system has already generated settings_uid for me:
Here the settings_uid is es9TCQpyHN24N2jyKBsttfM. With this setting, you should be able to download all those variables that you have checked under Select questions to be exported.
The settings_uid should be the same till the first export you have made (or if you have also cleared all the settings if there were multiple export settings made previously).
Now, I wish to change my export setting. So I changed the selected variables and renamed the Save selection as from My new exports to My second exports. Here you should see that the system should generate a unique and different settings_uid for me:
So once again, if you look at the API, you should see that the system has now generated a different settings_uid for me:
Here the newly generated settings_uid is esiaYFpiYymexSgbF8e6524. So with these settings, I will be able to download only Name and _id as shown in the image above.
In addition, if you have also not deleted the exports in the Download UI (as shown in the image below):
You should be able to see two different settings_uid in the API. But if you clear the Apply saved export settings, you will see the default settings_uid auto-generated at the very beginning.
