Pushing Data to KOBO (to fix image size)

[Josh]

Hi @caneeraj, if your goal is purely reduced image size, you can access your images in three different sizes already: original, large and small. If you navigate to:

https://KF_URL/api/v2/assets/ASSET_UID/data.json

You can see something like this for each image attachment for each submission:

If you still need/want to upload your submissions and media from Form A to Form B, this is possible but not trivial. You can take a look at my answers here for that:

Kobo submission edit by ASP.NET C# (Using API)

Hi @mizanvai — yes this is possible but, unfortunately it’s not very straightforward. I’m planning to do a tutorial on this soon but, in the meantime, you can have a look at my recent post here: And you can take a look at how we handle the new bulk edit feature here – you could essentially just adapt that code for .NET. The key takeaway is that you will need to move the submission’s current instanceID to a new deprecatedID and then create a new value for instanceID – you can read the code com…

Hope that helps.
