How can I pass a JS result into a Twig template?

Question

I've got a frontend form which queries the openstates.org API to return a given set of data objects.

Those objects also exist in Craft as entries, and the API data includes a field that serves as a unique ID for the Craft entries - how can I pass those unique IDs back to the Craft template to retrieve the corresponding entries?

You could add them as query string to the URL. When rendering the page, you can tan check the query strign to see which ones you'd have to display... — mrsmn, Jul 26 '17 at 05:57
Thanks, Michael - that worked perfectly. I wound up combining it with the sample code from this answer. — mierla, Jul 26 '17 at 15:23
Perhaps add your working combination as answer? That way people in the future can directly see the answer. — mrsmn, Aug 01 '17 at 13:24

Per Michael's suggestion above, with some help from this answer, I passed the results from the API call back to a craft template as query params, so it looked like this (simplified):

{% if craft.request.isAjax %}
    {% set myReps = craft.request.getParam('personId') %}
    {% set myIds = myReps | split(',') %}
    {% for myId in myIds %}
        {% set person = craft.entries.section('representatives').repId(myId).first() %}
    {% endfor %}
{% endif %}

and then output my info from there.
