PowerFlow block Reference | Documentation

As explained in Build a PowerFlow, PowerFlows are composed of a set of blocks that you connect, creating step-by-step actions to execute. Each block performs a specific function. Blocks are grouped into different categories to make them more accessible.

Flows in MediaFlows start with Trigger Blocks, which define how and when a flow is initiated. Triggers can be event-driven (e.g., a webhook call, an asset upload) or time-based (e.g., a scheduled task). Each flow must begin with a trigger block.

Triggers a flow whenever an asset is uploaded to Cloudinary.

• Optionally set up a filter to specify which assets trigger this flow.

• When an image is uploaded by a third party, automatically check if it contains a watermark.

Allows you to trigger flows manually from within the Cloudinary Media Library via the MediaFlows DAM App.

• Enable/disable Return results as array:
  • Enable the setting to execute the block once, regardless of how many assets are selected, and return the response for each asset in an array. This is often followed by an Iterate Assets block.
  • Disable the setting to execute the block for every selected asset.
• Set Input parameters. These are the names of parameters that you can set when you run the app. Subsequent blocks can access them as custom variables.

1. Enable the MediaFlows DAM App in Cloudinary's DAM App Marketplace.

2. Select an asset in Cloudinary's Media Library and click Run MediaFlows from the menu.

3. Choose the flow to execute.

• A user manually selects some images in the Cloudinary Media Library and triggers a flow. In a prompt parameter they ask a question about the image and the app sets the answer in the assets' metadata.

Only MediaFlows users can run DAM Apps (Master Admins and Admins).

Triggers a flow on a predefined schedule by searching for assets that match specific criteria.

• Set up a Recurring schedule (e.g., every Monday at 8:00 AM UTC) using an AWS cron expression.
• Define a Search expression to filter relevant assets (see examples).
• Set the Maximum assets to process. The flow processes only the first matching assets up to the set limit.

• Each day, apply a transformation to all assets uploaded in the last 24 hours.

Executes flows at predefined time intervals, similar to a cron job.

• Define an AWS cron expression for the Recurring schedule.

• Send a daily report on your account usage.

Initiates a flow when an HTTP request is received at a specific webhook URL. This allows external applications to trigger flows in MediaFlows.

• Copy the generated webhook URL.
• Paste the webhook URL into an external application's webhook settings.
• Specify any payload fields that you want to make available in subsequent blocks. For example, to access the notification type in a subsequent block, type notification_type and click the + button.

  In subsequent blocks you can use this variable with this syntax: {{$.Catch_Webhook.result.notification_type}} (automatically inserted when you use the insert variable functionality).

• A custom CMS sends a webhook to MediaFlows when an asset is updated. The flow checks the notification_type to determine whether the asset was tagged, renamed, or moved, and routes the logic accordingly.

Triggers a flow based on one or more Cloudinary webhook notifications. It's useful for notifications that don't have dedicated trigger blocks already defined, or if you want to set up one trigger for multiple notifications.

• Choose the types of notifications to listen for.

• A flow starts when a user moves an asset to a folder or uploads an asset to a folder.

• Some notifications may not be available for product environments using the legacy fixed folder mode.
• The structure of each notification is different so you need to take multiple structures into consideration.

Triggers a flow when a user moves an asset between folders in Cloudinary.

• Optionally set specific from/to folders and the type of assets that will trigger the flow.

• Moving an image into an "Approved" folder triggers a transformation process.

• Not supported for product environments using the legacy fixed folder mode.
• In legacy mode, moving an asset changes its public_id, triggering a rename notification instead.

Triggers a flow when an asset's structured metadata is modified.

• Specify the structured metadata changes and corresponding asset types that should trigger the flow.

• When an asset's "status" metadata changes to "archived," move it to a designated folder.

Triggers a flow when a tag is added to or removed from an asset in Cloudinary.

• Set up the filter to determine which tags trigger the flow.

• When an asset is tagged "featured," automatically generate social media versions.

These blocks can be used by any flow to implement logical flow functionality.

Evaluates JSON data against JsonLogic expressions to decide the flow's path.

• Add the JSON data you want to evaluate.
• Add a JsonLogic expression (see Example JsonLogic).

• If an image is grayscale, apply a tag.

• True → Block connected to the upper blue dot executes.
• False → Block connected to the lower blue dot executes.

Evaluates a comparison between two variables using a specified operator.

• The First variable must be a value from earlier in the flow, for example {{$.Apply_On_Each.result.item.asset_folder}}.
• Select the Operator from the list.
• The Second variable can be either a hard-coded value or one from earlier in the flow.
• Choose the Variable type (String, Number, or Boolean).

• Only continue the flow if an asset is in a specific folder.

• True → Block connected to the upper blue dot executes.
• False → Block connected to the lower blue dot executes.

Executes the next connected blocks on each asset in a list.

If the items in the list aren't Cloudinary assets, use

instead.

• Set the Source of asset list field to a list of assets (technically, a JSON array). For example, if the previous block is a Search Media block, which returns multiple resources, use the plus icon to insert the resources list from the Search Media block (equivalent to {{$.Search_Media.result.resources}}).

• Search for images with a particular tag and delete each of those images.

Executes the next connected blocks on each item in a list.

If the items in the list are Cloudinary assets, consider using

instead.

• Set the List to iterate field to a list of items (technically, a JSON array). For example, if the previous block is a Parse CSV Asset block, which returns multiple rows, use the plus icon to insert the list of rows from that block (equivalent to {{$.Parse_CSV_Asset.result.rows}}).
• Specify any fields from each item that you want to make available in later blocks. For example, to access the URL contained in each row of the CSV file in a subsequent block, type url (the column name) and click the + button.

  In later blocks you can reference this variable using: {{$.Iterate_List.result.item.url}} (automatically inserted when you use the insert variable functionality).

• Add a prefix to each product SKU in a list.

Pauses execution until all block executions following an Iterate List or Iterate Assets block complete.

• No configuration needed.

• Wait for all tags to be added before sending a confirmation message.

These blocks help with debugging, string operations, data shaping, and integration with external APIs.

Outputs a message in the execution logs, useful for debugging and tracking flow behavior.

• The message can be a combination of plain text and variables from previous blocks (e.g., {{$.Cloudinary_Upload.result.public_id}}).

• Log the name of each uploaded file during testing.

Pauses the flow for a specified number of seconds.

• Supports values between 1 and 240 seconds (up to 4 minutes).

• Wait 10 seconds before executing an API call to avoid throttling.

Concatenates two strings, optionally using a separator.

• Use variables or static strings.
• Optional separator adds characters between the joined values.

• Combine a folder path and filename into a full asset path.

Processes JSON data using a JQ expression.

• Provide the JSON input (e.g., {{$.Cloudinary_Upload.result}}) and the JQ expression.
• Outputs transformed data as JSON.

Transforms a JSON object into an array, embedding each original key into its corresponding item. This is especially useful for iterating over objects with the Iterate List block.

Specify a key name to include the original object key as a new property in each array item.

Example input:

With key name set to public_id, the output becomes:

• Provide a key name (e.g., "key") and a valid JSON object.

• Convert a list of assets presented as a JSON object from a webhook notification into an array for tagging.

Extracts parts of JSON using a JSONPath expression.

• Provide the JSONPath query using variables (e.g., {{$.Apply_On_Each.result.item}}.tags[*] to extract the tags from each search result).

• Pull public IDs from a list of assets with a particular tag ({{$.Search_Media.result}}..public_id).

Parses a CSV file into an array of objects, with keys from the first row of headers.

CSV files greater than 100 kB are not supported by this block.

• To specify the CSV file to parse, select a previous block that references it, or click Custom to specify a public ID, delivery type and resource type.
• Specify the CSV delimiter character (default is a comma ,).
• Choose whether to Skip empty lines in the CSV file. This includes both empty lines and lines containing all empty values.
• Choose whether to Trim values (remove leading and trailing whitespace from each cell).

• Import a list of product SKUs and metadata from a CSV file, then process each row to update asset metadata in Cloudinary.

Replaces parts of a string that match a given string or regex pattern.

• Specify the string on which to perform the replacements.
• The pattern to search for can be a regular expression or a plain string.
• If you leave the replacement value blank, the matched string is removed.

• Change dashes from metadata values to underscores before sending them to an external system:
  • Set Pattern to -.
  • Set Replacement value to _.
• Remove a file extension from a file name (this assumes three or four letters of any case after the dot at the end of the string):
  • Set Pattern to \.[a-zA-Z]{3,4}$.
  • Leave Replacement value blank.

Sends a request to a third-party API. You can use this block for integrating with external tools like CRMs, PIMs, or marketing platforms.

• Supports all HTTP methods (GET, POST, etc).
• Set headers and body in JSON format.
• Optionally include a response filter as a JQ expression to transform or extract data from the response JSON received by the block. This is useful for trimming down responses for subsequent blocks.

• Send asset info to a product database after upload.

If setting

in the Request Headers, you should specify the form fields in the Message Body.

Divides a string into an array using a defined separator. The output is a list, which you can feed into the Iterate List block.

• Separator supports plain text or regex.

• Split "shirt,hat,jacket" into separate tags.

Uploads a Cloudinary asset to an external HTTP endpoint using a multipart/form-data request. You can apply optional Cloudinary transformations to the asset before upload and include additional form fields in the request.

• Provide the endpoint where the asset should be uploaded.
• Choose the HTTP method (POST, PUT, etc.) that the target system expects.
• Add headers in JSON format if required (e.g., { "Content-Type": "multipart/form-data" }).
• Specify the form field name used to send the file (e.g., file or media).
• Optionally include additional key-value fields to accompany the file upload (in JSON format).
• Apply Cloudinary transformations in URL syntax before uploading (e.g., c_fill,w_300,h_300).

• After moderating an uploaded video, send the asset via POST to a partner system's API with a resized version and accompanying metadata as form fields.

These blocks interact with Cloudinary's APIs to manage, transform, and retrieve media assets.

Retrieves usage statistics for your Cloudinary account.

• No configuration needed; the block automatically fetches account usage details.

• Schedule a daily report summarizing storage and bandwidth usage.

MediaFlows has a number of useful blocks for specific integrations to Cloudinary. If there is an integration that you think should be added then please let us know.

You can use the

block for generic API calls to any integration not listed here.

You can use the Akeneo blocks only with Akeneo versions that support the Akeneo Asset Manager.

Use the Akeneo blocks to communicate with Akeneo's API, to create an asset, delete an asset, or get product information from Akeneo.

You must use a

block before you can use one of the other Akeneo blocks that requires a valid token. The token returned from the block is valid for any and all Akeneo blocks that follow, so you only need to use the Get Tokens block once for the entire flow that follows.

Retrieves authentication tokens from Akeneo so that other Akeneo blocks can access the Akeneo API.

Make sure you're registered to Akeneo in order to use this block.

• Copy credentials from the Akeneo Connections page.
• All other Akeneo blocks in the flow can use the tokens from this block.

We recommend that you create a new connection, and use the new credentials to configure this block.

• Authenticate once at the start of the flow before using any other Akeneo block.

Creates an asset in Akeneo's Asset Manager.

To allow this block to communicate with Akeneo's API, you must include a

block at some point in the flow before this block.

• Requires a valid access token (from Get Tokens From Akeneo).
• Use the Asset code and Asset family for automatic product linking using the asset family's Product Link Rules. See Example: Configuring a Product Link Rule.
• Asset Values can include additional attributes such as photographer, license date, etc.

• Automatically push a newly approved product image from Cloudinary to Akeneo and attach it to a product by SKU.

You can add any additional values as key/values in the Asset Values field. See the Akeneo documentation for more information and examples of passing these values. Note that you only pass the attributes as given in the values key.

The following example passes the photographer and end_of_use_date values:

Deletes an asset from Akeneo's Asset Manager.

To allow this block to communicate with Akeneo's API, you must include a

block at some point in the flow before this block.

• Requires a valid access token (from Get Tokens From Akeneo).

• Remove deprecated product images from Akeneo when they're archived in Cloudinary.

Fetches product information from Akeneo's Asset Manager using a product UUID.

To allow this block to communicate with Akeneo's API, you must include a

block at some point in the flow before this block.

• Requires a valid access token (from Get Tokens From Akeneo).
• Set various options defining what to return in the response.

• Retrieve product metadata and use it to set tags or metadata in Cloudinary.

Uploads a file to an AWS S3 bucket.

• Ensure the target bucket is whitelisted.
• Upload an asset from earlier in the flow, or specify one in your Cloudinary product environment.
• Specify the name of the AWS S3 bucket and the bucket region (if different from the default eu-west-1).
• Optionally choose a path and a new name for the asset (including the file extension).

• Archive optimized images in a private S3 bucket for long-term storage or sharing with partners.

In order to enable uploading to your bucket, your S3 storage bucket must be whitelisted. This requires the following steps:

1. Grant full access permissions to Cloudinary's AWS account, using one of the following methods:

   • AWS Console: Set up the bucket policy using this JSON code. Make sure to replace <your_bucket_name> with your bucket's actual value:
   • AWS CloudFormation: Use the following JSON within AWS CloudFormation to create the backup bucket. Make sure to replace YourBucketName with your bucket's actual value:

2. Add an empty file to your bucket with your cloud name as the filename, under the following folder structure: .wellknown/cloudinary/<your_cloud_name>

   • By adding this file, you indicate that you have access to this bucket and that you permit Cloudinary to access and modify this bucket's contents.
   • The file needs to be located in the Root Path as defined in the block.
   • If you want this bucket to be whitelisted for more than one Cloudinary product environment, you can add an appropriately named file for each cloud name.

If at a later point you need to update permissions on an existing S3 bucket, changes may take some time to propagate, and you may not see the changes taking effect right away.

Improves media quality using the Dolby.io Media Enhance API.

You need to register to

in order to use this block.

• Provide your Dolby API key and secret (available on the Dolby.io Applications Dashboard).

Use this Dropbox OAuth Guide to set up a Dropbox app. The main steps are as follows:

1. Head to the App Console and create an app.
2. Configure the app settings.
3. Configure the permissions. Ensure you allow read and write access to your files and folders, including the content and metadata.
4. Submit your configuration.

1. Navigate to https://www.dropbox.com/oauth2/authorize?client_id=<APP KEY>&response_type=code&token_access_type=offline (replacing <APP KEY> with the App key from the app's settings page).
2. Copy the access code that's generated.

1. In a terminal, enter the following command, replacing the placeholders with your information:

2. Copy the refresh_token from the response.

1. In the MediaFlows Upload To Dropbox block, set the Dropbox app key and Dropbox app secret with the values from your app settings, and the Dropbox refresh token that you generated.
2. Test your flow and check that an image is uploaded to your Dropbox.
