How can we help?
Short, practical guides for DynamiHost: creating codes, printing them so they scan, custom domains, analytics, the API, GS1 and billing.
Getting started
Create your first dynamic QR code
From sign-up to a printed code in about two minutes: pick a type, add your destination, style it, and download it.
Read the guideHow dynamic QR codes work
The printed code points at a short DynamiHost link, and that link forwards each scanner to your current destination.
Read the guidePrint QR codes that scan first time
Size, contrast, quiet zone and finish: the four things that decide whether a printed code scans in the real world.

URL, file, vCard, calendar event, app download, hosted page and GS1 Digital Link: what each type does and when to use it.
Read the guideHosted pages and hosted files
Build a landing page, digital business card, coupon or gallery in DynamiHost, or upload a file and serve it from a code.
Read the guidePassword protection, scheduling and expiry

Read the guideSmart routing rules
Send scanners to different destinations by device, country, language or time of day, from one printed code.
Read the guideWhy a QR code will not scan, and how to fix it
A checklist from the common causes: size, contrast, quiet zone, damage, and the code's own status.

Analytics
Read your scan analytics
Where scans are counted, what a unique visitor means, how retention works, and how to act on the insights.
Read the guideRetargeting pixels and conversion events
Add your Google or Meta pixel so scanners join your ad audiences, and record conversions against the code that drove them.

API keys and the REST API
Create a scoped API key, call the v1 API with it, and stay inside the rate limits.
Read the guideWebhooks: get notified on every scan
Receive a signed HTTP POST on each scan, verify the signature, and understand retries and auto-disable.
