FAQ
How are subscription links different from Shopify cart permalinks?
Shopify's built-in cart permalinks cannot apply selling plans — Shopify's own documentation says so. DropLink creates the cart through Shopify's Storefront API with the selling plan attached, so the buyer lands in checkout already set up as a subscriber. That works on every DropLink plan, including Free.
What does the buyer actually see?
They click your short link and land directly in your store's own Shopify checkout with the cart pre-filled. DropLink never handles payment, never shows its own pages to buyers (except a branded "link not found" for dead links), and never alters your checkout.
How does conversion tracking work?
Each link tags its checkout with a hidden cart attribute. When the order is paid, Shopify notifies DropLink and the order is attributed to the exact link that drove it — orders, revenue, and conversion rate per link. Conversion tracking is included from the Starter plan.
Analytics also split each link's orders into subscription vs one-time, so you can see which links recruit subscribers — plus an estimated annual recurring value (subscription revenue × 12, assuming monthly billing; a rough guide, not billed reality).
What counts as a click vs. a unique visitor?
Every redirect is a click. Unique visitors are estimated from a salted hash of the visitor's IP — the raw IP is never stored. After 90 days, raw click rows are rolled up into daily summaries, so totals are preserved forever while detailed data ages out.
How does A/B testing pick a variant?
Traffic splits by the weights you set. A visitor who returns within 30 days keeps the variant they were first assigned (via a cookie), so refreshing doesn't skew your results. Conversion and revenue are tracked per variant, and you can apply the winner's configuration to the link in one click.
What happens when I hit my plan's link limit?
Existing links keep working — you just can't activate new ones. Upgrade, or pause/archive links you're not using. Downgrading never deletes anything.
Can I cancel or change plans any time?
Yes. Billing runs through Shopify's own subscription system — changes happen on Shopify's secure pricing page and show up on your normal Shopify invoice. Every paid plan starts with a 14-day free trial.
What data does DropLink store, and what about GDPR?
Per click: a salted hash of the IP (not reversible), user agent, referrer trimmed to origin+path, and country. Per conversion: the Shopify order ID and total. No buyer names, emails, or addresses — ever. When you uninstall, Shopify's mandatory data-erasure process deletes everything we hold for your store within 48 hours.
Can I use my own domain for short links?
Yes — on the Growth plan. Add a subdomain like go.yourstore.com in
Settings → Custom domain, point one CNAME record at customers.zerglo.com,
and your links, QR codes, and copy buttons switch to your domain with TLS
handled automatically. Full steps in the
custom domains guide.
Can I schedule when a link works?
On Starter and above you can set a start time, an expiry, or both — in the timezone of your choice (your store's timezone by default, shown next to each field). Before a link's start it shows a branded "opening soon" page; after it expires it shows the standard "link not found" page. Times are stored as exact moments, so a schedule fires at the same instant for every buyer regardless of where they are.
Can I make a one-time or gift link?
On Starter and above you can cap a link to a set number of orders. Unlike click-based limits — which a bot, a link preview, or a curious refresh can burn — DropLink counts completed paid orders, so the cap reflects real claims. Set the cap to 1 for a single-use link, or pair it with a subscription product to gift a subscribe-and-save that exactly one person can redeem. Once the cap is reached the link shows a branded "fully claimed" page. Because the count is based on completed orders, a burst of simultaneous checkouts can occasionally let a couple through beyond the cap. The cap keeps working even if you later move to a plan without order limits.
Can I customize my QR codes?
Every link comes with a downloadable QR code on every plan. On Starter and above you can brand it — set the foreground and background colors, add a center logo, and export a print-ready SVG alongside the PNG. The logo you add stays in your browser and is baked into the file you download; DropLink never uploads or stores it. However you style a QR, it always encodes the same short link, so codes you've already printed keep working.
Can I create a link from a past order?
Yes — on Starter and above, open Links → Create from order, search an order number (or pick a recent order), and its items land in a new link. Assign a selling plan to each item to turn a one-time order into a subscription ("loved your last box? get it monthly"). Notes:
- Orders older than 60 days aren't reachable through Shopify's API.
- Products that were deleted since the order are skipped, with a notice.
- Selling plans aren't copied from the order — you choose them in the form.
