Cloudinary App Guide

After you’ve installed the Cloudinary app, you can easily reference assets hosted on Cloudinary directly inside the Contentful web app.

Apps Cloudinary Dialog


The Cloudinary app is a widget that allows editors to select media from their Cloudinary account. Simply click Select or upload a file on Cloudinary and select the assets you want to be referenced from your entry.

The IDs of selected media are then stored in Contentful. Inside your client application, you then fetch content from Contentful and resolve all needed details on media by using the IDs to fetch binaries or metadata from Cloudinary's API.


To use this app, you will need:

  • The cloud name of your Cloudinary account.

  • The API key of your Cloudinary account.

  • A content type with a field of type "JSON object" to hold the references to Cloudinary.

You can find both cloud name and API key on your Cloudinary dashboard.


Step 1: Install and configure

Under Configuration, provide your Cloudinary cloud name and corresponding API key in the respective fields. By changing "Max number of files" you can also limit how many individual files users can select in a single field.

Under field assignment, select the content type fields that you want this app to be used for. Please note that only compatible fields of type "JSON object" are displayed here.

Step 3: Enable External references

To deliver Cloudinary's data using the Contentful GraphQL API you must first enable External references by selecting the Resolve content on delivery check box in the field editor of your desired content type.

To enable the Resolve content on delivery check box:

  1. Log in to the Contentful web app.

  2. Navigate to the "Content model" tab and select the content type with the Cloudinary app field setup.

  3. On the field used with the Cloudinary app, click Edit. The field editor is displayed.

  4. In the "Appearance" section, under "Choose how this field should be displayed", select Cloudinary App.

  5. Select the Resolve content on delivery check box.

  6. Click Confirm.

  7. Save your changes.


There are no content types with JSON Object field, help!

Cloudinary saves data into a Contentful entry using JSON data. If you'd like to associate Cloudinary assets with a specific content type, you must update that content type to include a new field which is of type JSON Object. Learn more about the JSON Object field type in our concepts documentation.

What to do if the entry editor displays the warning Field value is incompatible?

The JSON object field of this entry already contains data that was not generated by the Cloudinary assets app. Please ensure that you've selected the correct field in the app configuration to be used with Cloudinary, and that you do no longer need the previously entered data. Then select I want to override the value using the App., which will initialize the field with an empty selection. Now you can start to add media to your entry.

To access the underlying field value, deselect the field in the Cloudinary app configuration. This will reset the editor to the default json display for object fields
