Templates

To fetch the Instagram posts, use the craft.instagram.getFeed() function:

{# fetch account specified in settings #}
{% set items = craft.instagram.getFeed() %}

So you can iterate over all posts like this:

{% for item in craft.instagram.getFeed() %}
<a href="https://www.instagram.com/p/{{ item.shortcode }}/" target="_blank" rel="noopener noreferrer">
  <img src="{{ item.thumbnail }}" alt="" />
</a>
<p>{{ item.caption }}</p>
<p>{{ item.likes }} Likes / {{ item.comments }} Comments</p>
{% endfor %}

If you are using a volume to store the images locally, you have a full asset object and you can do things like this:

{% for item in craft.instagram.getFeed() %}
<a href="https://www.instagram.com/p/{{ item.shortcode }}/" target="_blank" rel="noopener noreferrer">
  <img src="{{ item.asset.getUrl({ mode: 'fit', width: 100, height: 100, format: 'webp'}) }}" alt="" />
</a>
<p>{{ item.caption }}</p>
<p>{{ item.likes }} Likes / {{ item.comments }} Comments</p>
{% endfor %}

You can also pass an account name or hashtag to overwrite the default from the settings:

{# fetch account by name #}
{% set items = craft.instagram.getFeed("codemonauts") %}

{# fetch hashtag #}
{% set items = craft.instagram.getFeed("#mrmcd2019") %}
