QR code guides

A campaign report is easy to read as a total and easy to misread as anything more. Here is what each breakdown tells you, where it is approximate, and how to compare placements fairly.

Qrop can post each tracked scan to an address you choose. Here is how to add an endpoint, check the signature, cope with duplicates, and replay scans after your server was down.

A logo covers part of the code, so the API handles size and error correction for you. What it can't do is judge your artwork. Most scan failures with logos come from the image you send, not the request you make.

The format field looks like three interchangeable image types. It isn't: one of them drops your logo without telling you, and the one that sounds print-ready is a raster image in a PDF wrapper, not a vector file.

There's no usage.threshold_reached event to subscribe to. If you want to know your credits are running low before a request gets a 402, you're polling GET /api/v1/usage yourself, and that's simpler than it sounds.

Picking L, M, Q, or H by hand makes sense for one code. At 10,000 codes a run, the decision has to be made once, upfront, and it changes based on the pipeline, not the individual destination.

Rotating a key doesn't have to mean a maintenance window. Here's how the 24 hour grace period works, and the order of operations that keeps every server serving requests the whole time.

A 429 isn't a credit problem, it's a pace problem. Here's exactly what trips Qrop's rate limits, how Retry-After tells you what to do next, and how to design around both at real volume.

One request, up to 25 QR codes back. Here's exactly how the batch endpoint works, what it shares across items versus what stays per-item, and how to scale past a single call.

One credit turns a plain QR code into a live, measurable, editable redirect. Here's a straightforward way to decide which of your codes actually need that.

A trade show table, a multi-location print run, or a seasonal ad test rarely lives on one code. Campaigns group tracked codes together so you see how the whole thing performed, not just one square of it.

From a Wi-Fi code typed into the dashboard to a QR code stamped on every order automatically, here's how small enterprises actually use Qrop's UI and API day to day.

From a free code for a market stall to a metered API behind a growing platform, here's the Qrop plan that actually fits your business, whatever size it is today.

Scan tracking is coming to Qrop: turn any QR code into a redirect you can measure, group, and edit after it's printed. Here's what's shipping and how it will work.

A QR code you can't measure is a leap of faith. Here's what scan tracking actually tells you, and how to use it without overreading noisy numbers.

Paper cards and QR codes solve the same problem differently. An honest look at cost, contact capture, and when each one actually wins.

Most QR code tools sell subscriptions to redirect infrastructure. We chose not to. Here's the reasoning, and how to get every platform benefit without one.

From restaurant menus to payment networks, QR codes went from niche curiosity to universal shortcut. Here's why they work so well and how to use them to their full potential.

Paid credits and API subscriptions are live on Qrop. Here's exactly how the billing model works (free tiers, credit packs, and metered API plans) with examples.

Let guests join your network with a scan instead of typing a long password. Here's how Wi-Fi QR codes work and how to make one.

Put your full contact card on a business card or badge, one scan saves your details straight to the phone's address book.

L, M, Q, H, what they mean, how much damage a code can survive, and why adding a logo forces the highest level.

Branding a QR code is easy to get wrong. Here are the contrast, logo-size, and quiet-zone rules that keep custom codes readable.

Replace printed menus with a single scan. Here's how to set one up properly, and the mistakes that frustrate diners.

Both are scannable codes, but they store data very differently, here's what sets a QR code apart from a traditional barcode.

Static codes never change. Dynamic codes can be redirected after printing. Here's the real trade-off behind the marketing term.
