How it Works - No Code Required
Link your Shopify account to Data8 and manage data quality from the same place you already run your store.

Connect Your API Key
Paste in your Data8 API key and we check it's valid on our end the moment you enter it - no separate confirmation step.

Choose Your Services
Turn on validation and PredictiveAddress individually. Only pay for what your checkout actually uses.

Place it in Checkout
Add the block in Shopify's checkout editor and drag it wherever it works best.
Three Solutions. Switch on whichever your checkout needs.
Each service is enabled independently, so data quality checks only run against the data sources that are actually relevant to your store.
Phone Validation
Checks numbers are real and correctly formatted, including full international phone validation for customers ordering from outside the UK.
Email Validation
Confirms deliverability at checkout, so order confirmations and shipping updates don't bounce.
PredictiveAddress
Type-ahead address lookup that also returns UPRN and UDPRN references, giving every order a precise, uniquely identifiable delivery point.
Install in one click from the Shopify App Store

Shopify Extension FAQs
Which data validation services can I enable in Shopify?
After your API key has been validated, you can choose which services you want to use across email validation, phone validation and predictive address. You can update these selections later if needed.
How can I download the Data8 data validation extension?
You can download the app here from the online store, no code or complex steps required.
How do I find my API key for Shopify?
For existing customers, you can find your API key for Shopify in the Data8 portal. Copy this, then head into the Shopify Store. Select Data8 Validation > Settings and paste your API key in.
We will then check to confirm you have a valid API key.
How do data validation credits work with Shopify checkouts?
Credits can be purchased from Data8’s online portal or directly within the Shopify app, which are then used to access data validation services that are relevant to your store.
Why use Data8 instead of Google's validation?
Google’s service is primarily designed to validate and standardise postal addresses. Data8’s Shopify extension for data validation can provide additional capabilities such as:
- AI-powered address autocomplete
- Email validation
- Phone validation
- what3words integration
- International data validation and enrichment
- Configurable validation rules tailored to business needs
