The URL needs to be accessible from all CHILI servers. Make sure that your firewall settings allow a connection and test the URL from the servers themselves.A way to get dynamic assets (images) into CHILI publisher, is to call a (public) URL. Or, at least a URL that is reachable from the CHILI instance.

Steps to take

• Define a DAP URL in the BackOffice

• Create a variable in your document to add to your URL

• Use an Image Frame in your document, containing the variable

• Asset Folder: Defines the location where the "high resolution" assets will stored when an output is made of the CHILI publisher document.

• Provides file info / File info URL: A URL where information about the assets can be found (width, height, resolution). See example below.
  If this information is not provided via a URL then it needs to be specified in the fields available when this checkbox is unchecked.

FileInfo XML example

<item name="dynamic-asset-name-here.jpg">
  <fileInfo resolution="72" width="834" height="592">
    <metaData>
      <width>834</width>
      <height>592</height>
      <resolution>72</resolution>
    </metaData>
  </fileInfo>
</item>

Using the Dynamic Asset Providers in a document

To use a Dynamic Asset image in a document, a variable of type image is created.
This variable is assigned to an image frame.
In the "Type Specific" settings" of the variable the source is set to "Dynamic Asset Provider". 

...

Select the "Dynamic Asset Provider" settings you've created in the backoffice and specify which value you want to use to create personalised images.

To specify a specific variable to be used provide the name of the variable in between 2 "%" characters.

...

This way you can combine fixed text with a variable or combine several variables. So information for the service along with information from the document can be combined.

The images below show an example where GoogleMaps API Static Maps has been setup to create a map that uses information from variable fields in the document to update the image and send the result back to CHILI publisher to be shown in the document.
