The workflow simply responds to a web request that will be coming via Javascript and responds with the inventory levels.

Liquid code for theme

You’ll want to copy and paste this code into a Custom Liquid section in the Theme Editor for your Product Page.

Note: this works for Dawn themes but custom themes may require some specific adjustments to this.

<fieldset class="js product-form__input">
  <legend class="form__label">Available Inventory</legend>
  <div id="mesa-output"></div>
</fieldset>

<script type="text/javascript">
  const WEBHOOK_URL =
    'https://webhooks.getmesa.com/v1/kalen-test-store/webrequest/66c8f84efa82fcb17905350d/66c8f84efa82fcb17905350f.json?apikey=p234WHl7GU5B9UC5xpGg35JrhXajoW38aWlhKxTI';

  function fetchJSON(url) {
    return fetch(url)
      .then((response) => {
        if (!response.ok) {
          throw new Error('Network response was not ok');
        }
        return response.json();
      })
      .catch((error) => {
        console.error('There was a problem with the fetch operation:', error);
      });
  }

  function showInventoryForVariant(variantId) {
    const outputDiv = document.getElementById('mesa-output');
    outputDiv.style.opacity = 0.5;

    url = WEBHOOK_URL + '&variant_id=' + variantId;
    console.log("MESA fetching inventory levels data: " + url);
    fetchJSON(url).then((response) => {
      let data = response.response;
      console.log("MESA inventory levels data: ", data);

      let levels = data.map((object) => {
        return object.location.name + ': ' + object.quantities[0].available;
      });

      let output = levels.join('<br>');
      outputDiv.style.opacity = 1;
      outputDiv.innerHTML = output;
    });
  }

  window.addEventListener('DOMContentLoaded', () => {
    let variantId = '{{product.selected_or_first_available_variant.id}}';
    showInventoryForVariant(variantId);

    subscribe(PUB_SUB_EVENTS.variantChange, (event) => {
      console.log('Variant change event:', event);
      let variantId = event.data.variant.id;
      showInventoryForVariant(variantId);
    });
  });
