Make an image private

You can require an image to only be accessible with a signed URL token. To make an image private, pass a JSON blob with the requireSignedURLs property set to true at the time you request a one-time upload URL:

curl --request POST \
  --url https://api.cloudflare.com/client/v4/accounts/<ACCOUNT_ID>/images/v1/direct_upload \
  --header 'Content-Type: application/json' \
  --header 'Authorization: Bearer :token' \
  --data '{
	  "requireSignedURLs":"true"
   }'

If an image is marked to require signed URLs, it can only be accessed using a signed URL token or using a Variant with Always allow public access property checked.
