You know what's worth celebrating? SPACE. Use this task to activate a discount code every time the International Space Station passes over your store (or some other location of your choice), powered by Mechanic webhooks, IFTTT, and NASA. πŸš€

To get set up, follow our guide on Triggering tasks with IFTTT, with these modifications:

  1. When configuring your Mechanic webhook, use the event topic user/space/iss.
  2. When choosing an IFTTT service (for "+this"), search for and select the "Space" service.
  3. When choosing an IFTTT trigger, select "ISS passes over a specific location", and choose the location of your store. Or, whatever location you prefer. :)
  4. When configuring the webhook action, set the content type to "application/json", and set the body to the following code:

    { "duration_seconds": "{{DurationSeconds}}", "location_map_url": "{{LocationMapUrl}}" }

That's it! :) Every time the ISS arrives at your location, this task will activate the discount code of your choice (re-activating it when it already exists, and creating it if it does not), setting it to expire when the ISS departs.

      Hello,

      Mechanic has just activated the discount code <b>{{ discount_code_code }}</b> (for {{ options.discount_percentage__number_required }}% off), to celebrate the International Space Station arriving <a href="{{ event.data.location_map_url }}">at your store</a>!

      The ISS will be overhead for {{ minutes }}m{{ seconds }}s, so the discount will be active from {% if ends_same_day %}{{ starts_at | date: "%l:%M %p" }} to {{ ends_at | date: "%l:%M %p" }} ({{ "now" | date: "%d %b" }}){% else %}{{ starts_at | date: "%d %b %Y at %l:%M %p" }}, to {{ ends_at | date: "%d %b %Y at %l:%M %p" }}{% endif %}. You can manage it from <a href="https://{{ shop.domain }}/admin/discounts?query={{ discount_code_code }}">your Shopify admin area</a>.

      Thanks,
      Mechanic, for {{ shop.name }}
