Upload a File to the Cloud
Thunkable integrates with Cloudinary, a service that allows you to store media files in the cloud. The upload file block allows you to send media directly from your Thunkable app to a linked Cloudinary account.
Connect Your Cloudinary Account to Your Thunkable Project
Thunkable provides a shared Cloudinary account for your convenience, but we strongly recommend creating your own account to ensure privacy for your uploaded media. In addition, the shared Thunkable Cloudinary account has a media size limit of 10MB per app and your files will be deleted after 90 days.
To connect your Cloudinary accout to your Thunkable project:
Create a free Cloudinary account here: cloudinary.com.
From your Cloudinary dashboard, retrieve the following account details:
