JSONPath notation

JSONPath is a query language for JSON. A JSONPath expression specifies a path to an element in a JSON structure.

JSONPath expressions, including property names and values, are case-sensitive.

Paths use the dot notation: $[0].title

$The root object or array.
.propertySelects the specified property in a parent object.
[n]Selects the n:th element from an array. Indexes are 0-based.


An index, as referred to by 'n' in the above table, may be replaced with an iterator expression.
Doing so means the index referred to by 'n' will start at 0 and then increment at an interval.

Means 'n' starts at 0 and increments by 1 every 20 seconds.

Publishing a JSON file using Smartsign

Typically the source of the json-file comes from an external system or API and it's already available via http(s).

Sometimes this link cannot be reached directly from the Smartsign server or a screen. In such a scenario it's possible to store the file to the Smartsign Media library and re-publish it from there in order to make it accessible where needed.

You can upload the file to the media library manually or by using Smartsign Sync (min version 10.22.1).

Once the file is uploaded, view the resulting media item and go to the Advanced tab.

Enable the setting Allow anonymous access.

Once enabled, a Permalink will generate and show.

This link will not change if you update or replace the file and can be used to fetch the files content from template creator.
