UPDATE 5/8/2018,Le bijou d’amour 12 p.m. ET: Instagram officially announced the launch of "action buttons" for businesses on Instagram. These actions include the ability to buy, reserve, and book whatever the vendor is selling. Partners include EventBrite, StyleSeat, Resy, MindBody, and more. Original story follows below.

The time and energy gap between seeing something, desiring it, and actually buying it, is shrinking to almost nothing.

Instagram users have reported the appearance of in-app purchases, according to TechCrunch. With this new capability, when stores post a product that catches an Instagram scroller's eye, users could click to buy without ever leaving the Instagram app.

The new capability is tied in with booking and reservation services, which Instagram announced in March 2017. That means if you're looking for a #brunch spot on Instagram, you can make a reservation in-app at whichever restaurant's huevos catch your eye.

Instagram is working with a number of partners for the in-app purchases and reservations. Its current partner for the restaurant booking feature is Resy, the reservations service.

"Resy integrated with Instagram, so users can book reservations (via Resy) directly through the partner restaurant's Instagram account," a Resy spokesperson said.

To book, Instagram users go to the profile page of the restaurant, and click reserve. Then, a Resy widget pops up that allows users to select a time. Instagram users will have to sign in with (or sign up for) Resy accounts — an Instagram profile isn't enough to make it a done deal. However, it seems that once you log in to Resy once, you're good to make more reservations without entering your details again.

When Instagram first announced the booking feature, it didn't appear to have a credit card integration; the example it gave includes a payment portion that said "payment in person at the time of appointment." But Resy, and the in-app purchases feature, require a credit card tied to your account, similar to in-app payment on Messenger.

Since Instagram is such a natural hub for products, food, and beauty, this new capability could be huge for businesses. I know that for me, Amazon Prime's one-click shopping has led to many a compulsive purchase — purchases that I might not have made if I'd had even those few extra minutes or even seconds necessary to leave the Prime universe, and enter credit card and shipping info.

So with that same instantly purchasable and bookable power on Instagram, users could find themselves turning from scrollers to buyers in a matter of seconds. How beautiful.

UPDATE May 4, 2018, 3:00 p.m. E.T.: Resy sent Mashable a statement clarifying its reservation policy:

All Resy users have a credit card tied to his/her account. Less than 1% of the restaurants who use Resy actually ask for a deposit. But what has become very effective is for restaurants to ask for a credit card upfront as a way of discouraging no showing (each restaurant sets their own fee for no shows and cancellations - not Resy).
