Hi, I just bought a licence of the Multi-uploader plugin. I do have an Uploadcare account, however, it is not possible to enter the key on the pluggin. I only see fields for Filestack and Azure. See screenshot.
Any advice?
Hello, @Audrey_zero
Thanks for using our plugin 
Firstly, allow me to advise you to check the plugin’s documentation:
https://docs.zeroqode.com/plugins/multi-uploader-plugin#i.-getting-the-plugin-keys-if-you-have-chosen-one-of-the-above-services-.
After signing up and receiving your email confirmation, you will be transferred to Dashboard, where you can create a new project or use a default one.
Copy the project’s public key:
This key you should enter here:
Hope it will help you 
Best regards,
