[Resolved] Use json data as variable in views filter

I am trying to create a view that filters posts based on a shortcode attribute. The attribute to be provided is supplied from json data that is loaded on the page. I'm using handlebars.js to render a template that displays some of the data. I then want to say "where the value from this json object equals the value of shortcode attribute/field, display the view"

So the resulting code looks like this:

[wpv-view name="grab-categories" billid2="{{billId}}"]

The problem appears to be that the handlebars template does not render before the view evaluates the shortcode, resulting in it passing the markup (I.e. '{{billId}}') rather than the value. Which isn't surprising. I've tested the view by supplying an actual value instead of markup and the view works.

So I guess my question is, is there a way to do what I'm trying to achieve with Views? Is there a way, for example to ensure that it evaluates the value not the handlebars markup? Can you suggest another way to use the value of a json object as the value in the shortcode?

Well there is no JavaScript API for Views, so there's no built-in way to achieve JS-based filtering from the front-end of the site. The results are pre-determined before the page loads, so obviously front-end code will not influence the initial View results. If you have access to the JSON object in PHP before the page loads, you can use the Views API instead of the View shortcode to render the View. Instead of including billid2 in the shortcode attribute, you would include it in the args array. We have documentation about the render_view API available here:
https://toolset.com/documentation/programmer-reference/views-api/#render_view

For example:

$args = array(
    'name' => 'grab-categories',
    'billid2' => 'some value'
);
echo render_view( $args );

Thanks. I’ll dig in on that approach.
