Enable vary for images

Vary for Images is enabled through Cloudflare’s API by creating a variants rule. In the examples below, learn how to serve JPEG, WebP, and AVIF variants for .jpeg and .jpg extensions.

​​ Create a variants rule

curl -X PATCH
"https://api.cloudflare.com/client/v4/zones/023e105f4ecef8ad9ca31a8372d0 c353/cache/variants" \
-H "X-Auth-Email: user@example.com" \
-H "X-Auth-Key: 3xamp1ek3y1234" \
-H "Content-Type: application/json" \
--data
'{"value":{"jpeg":["image/webp","image/avif"],"jpg":["image/webp","image/avif"]}}'

​​ Modify to only allow WebP variants

curl -X PATCH
"https://api.cloudflare.com/client/v4/zones/023e105f4ecef8ad9ca31a8372d0 c353/cache/variants" \
-H "X-Auth-Email: user@example.com" \
-H "X-Auth-Key: 3xamp1ek3y1234" \
-H "Content-Type: application/json" \
--data
