Different online services, websites and mobile applications have very different image management requirements. Despite the differences, the image management pipeline boils down to the same basic formula - upload the images, normalize them, store them and manipulate them to create derivatives (thumbnails, effects, watermarks, etc.). Afterwards, prepare them for delivery and make sure they are accessible to your users quickly and efficiently when browsing your website or using your mobile app.

When we set out to build Cloudinary, we envisioned a platform that could streamline an online service's entire asset management pipeline needs. We developed a simple yet powerful URL based API and made integration even simpler using client integration libraries for many web dev platforms and programming languages. It was a joy to see how each of our clients found new ways of utilizing our platform, hooking different API calls to solve scenarios we could barely imagine when Cloudinary was first conceived.

Management Console for manually achieving such tasks via our web-based user interface. But as many of our customers told us and frequently requested, more control is sometimes required than what they can currently achieve manually. In the regular flow of web applications, this works perfectly. But sometimes, you'll want even more fine grained control over your online assets - browse through user uploaded images, find specific images, delete images, delete transformations and more. If you already tried Cloudinary, you probably know that you can use ourfor manually achieving such tasks via our web-based user interface. But as many of our customers told us and frequently requested, more control is sometimes required than what they can currently achieve manually.

Today, we've made another important step in making the Cloudinary platform even more customizable.

Without further ado, we'd like to welcome Cloudinary's powerful new administrative API , an intuitive RESTful HTTP API for programmatically managing all of your Cloudinary hosted assets.

Supported Operations

When building the API, we did our best to cover all common management tasks:

Listing all uploaded images and raw files.

Receiving details and metadata for uploaded images, including timestamps, format, dimensions, etc.

Listing the derived images of uploaded images.

Finding all images that share a given tag.

Listing all transformations.

Listing tags.

Receiving transformation details.

Creating named transformations.

Updating an existing transformation.

Deleting images, raw files, derived images and transformations.

API Overview

The API is accessed using HTTPS to endpoints in the following format:

https://api.cloudinary.com/v1_1/:cloud_name/:action

For example, resource listing of the 'demo' account:

https://api.cloudinary.com/v1_1/demo/resources/images

Authentication is done using Basic Authentication over secure HTTP. Your Cloudinary API Key and API Secret are used for the authentication.

Request parameters are appended to the URL. The response is in a simple JSON snippet. Like any REST API, read-only requests are sent in HTTP GET while write requests are sent in PUT, POST and DELETE.

For more details, check out our documentation page

Our client libraries provide an easy to use wrapper for this URL-based API, utilizing your native programming language of choice. Request building and authentication are done automatically, and the JSON response is parsed and returned.

Usage Examples

The following Ruby example lists all your Cloudinary hosted images:

Copy to clipboard $ result = Cloudinary :: Api .resources => { " resources " => [{ " public_id " => " sample1 " , " format " => " png " , " version " => 1349196740 , " resource_type " => " image " , " type " => " upload " , " created_at " => " 2012-10-02T16:52:20Z " , " bytes " => 71376 , " width " => 261 , " height " => 253 , " url " => " https://res.cloudinary.com/sam/image/upload/v1349196740/sample1.png " , " secure_url " => " https://d3jpl91pxevbkh.cloudfront.net/sam/image/upload/v1349196740/sample1.png " }, { " public_id " => " sample2 " , " format " => " png " , " version " => 1349196732 , " resource_type " => " image " , " type " => " upload " , " created_at " => " 2012-10-02T16:52:12Z " , " bytes " => 133171 , " width " => 278 , " height " => 432 , " url " => " https://res.cloudinary.com/sam/image/upload/v1349196732/sample2.png " , " secure_url " => " https://d3jpl91pxevbkh.cloudfront.net/sam/image/upload/v1349196732/sample2.png " }, ... ], " next_cursor " => " e39ef944e18cfda7deafa4aea96791e7 " }

Here's the same example in PHP:

Copy to clipboard require " cloudinary.php " ; require " api.php " ; $api = new \ Cloudinary \ Api (); $result = $api ->resources();

Python:

Copy to clipboard import cloudinary.api result = cloudinary.api.resources()

And Node.js:

Copy to clipboard var cloudinary = require( ' cloudinary ' ); cloudinary.api.resources( function (result) { console.log(result) });

By default, 10 results are returned in a single request. You can specify the max_results parameter if you want more results in a single request. You can use this in conjunction with the next_cursor parameter for paginating through all your assets.

The next example shows how to get the full details of a single uploaded image, including the list of its derived images:

Copy to clipboard $ result = Cloudinary :: Api .resource( " sample1 " ) => { " public_id " => " sample1 " , " format " => " png " , " version " => 1349196740 , " resource_type " => " image " , " type " => " upload " , " created_at " => " 2012-10-02T16:52:20Z " , " bytes " => 71376 , " width " => 261 , " height " => 253 , " url " => " https://res.cloudinary.com/sam/image/upload/v1349196740/sample1.png " , " secure_url " => " https://d3jpl91pxevbkh.cloudfront.net/sam/image/upload/v1349196740/sample1.png " , " next_cursor " => " f329da74de2a9ac9cbf99d2a6bc147b8 " , " derived " => [{ " transformation " => " c_fill,h_50,r_20,w_70 " , " format " => " png " , " bytes " => 7313 , " id " => " a3b44a715c63f7ee91f11fb20b97c5df " , " url " => " https://.../sam/image/upload/c_fill,h_50,r_20,w_70/v1349196740/sample1.png " , " secure_url " => " https://.../sam/image/upload/c_fill,h_50,r_20,w_70/v1349196740/sample1.png " }, { " transformation " => " c_fill,h_75,w_75/jpg " , " format " => " jpg " , " bytes " => 2889 , " id " => " 7c0ca85b966b928179ce336fa2a7d1f8 " , " url " => " https://.../sam/image/upload/c_fill,h_75,w_75/v1349196740/sample1.jpg " , " secure_url " => " https://.../sam/image/upload/c_fill,h_75,w_75/v1349196740/sample1.jpg " }]}

And now, the same example in PHP:

Copy to clipboard $result = $api -> resource ( " sample1 " );

Python:

Copy to clipboard cloudinary.api.resource( " sample1 " )

And Node.js:

Copy to clipboard cloudinary.api.resource( " sample1 " , function (result) { console.log(result) })

One final example - getting the details of a single transformation, including a list of all images assigned to this transformation:

Copy to clipboard $ result = Cloudinary :: Api .transformation( " c_fill,h_75,w_75/jpg " ) => { " name " => " c_fill,h_75,w_75/jpg " , " allowed_for_strict " => false , " used " => true , " info " =>[{ " width " => 75 , " height " => 75 , " format " => " jpg " , " crop " => " fill " }], " derived " => [{ " public_id " => " sample1 " , " resource_type " => " image " , " type " => " upload " , " format " => " jpg " , " url " => " https://.../sam/image/upload/c_fill,h_75,w_75/v1349196740/sample1.jpg " , " secure_url " => " https://.../sam/image/upload/c_fill,h_75,w_75/sample1/sample1.jpg " , " bytes " => 2889 , " id " => " 7c0ca85b966b928179ce336fa2a7d1f8 " }, ... ]}

As you can see, the new API is quite powerful. Using this API allows for full control of all uploaded raw files and images, fetched social profile pictures, generated transformations and more.

Usage Limits

You can use the new API quite extensively. We ask for that you keep your ongoing API requests to 500 per hour (12,000 daily) when using our Free plan. Subscribe to Cloudinary's Basic plan onward to increase the limit to 2000 calls per hour. If you require more flexible limits, don't hesitate to contact us

For each API call, standard HTTP headers are returned with details on your current usage statistics, including your per-hour limit, remaining number of actions and the time the hourly count will be reset.

Here is how these headers might look like:

X-FeatureRateLimit-Limit: 500

X-FeatureRateLimit-Remaining: 499

X-FeatureRateLimit-Reset: Wed, 03 Oct 2012 08:00:00 GMT

Note that our client libraries provide easy access to the returned limit headers. In Ruby for example:

Copy to clipboard $ result = Cloudinary :: Api .resource_types => { " resource_types " =>[ " image " ]} $ result.rate_limit_allowed => 500 $ result.rate_limit_reset_at => 2012 - 10 - 03 10 : 00 : 00 + 0200 $ result.rate_limit_remaining => 499
