Cloudimage - Documentation

Accounts created before Nov. 1st, 2021

Accounts created before November 1, 2021 have to include /v7/ in the path, like shown below.

//token.cloudimg.io/v7/original_image_url?operations&filters

Accounts created on or after November 1, 2021 do not require /v7/ and documentation have been updated accordingly.
To verify the type of configuration on your Cloudimage account, log in to your Cloudimage admin panel and look at the syntax provided on the Welcome page.

[NOTE] If you are an existing Cloudimage customer and wish to be able to remove the v7 from your URL syntax, please contact our support.

URL signature

To prevent URL tampering and protect your token, every Cloudimage URL can be secured with an SHA-1 HMAC signature.

Please be aware that when URL signature is activated for your token, all Cloudimage URLs which are not signed properly will cease to work.

The signature is calculated as follows:

Signature = sha1('Salt' + 'URI') where URI = original_image_url?operations&filters

The syntax to process an image is:

//token.cloudimg.io/original_image_url?operations&filters&ci_sign=Signature

Because the Salt is a shared secret between you and Cloudimage, only you will be able to calculate the signature of your images.

Contact us to enable the signature and set up the Salt for your company token.
