Practical walkthroughs for integrating Checkify into your app. Each guide takes you from zero to working code in minutes.
Add Address Autocomplete to Your Forms
Add unit-level Australian and New Zealand address autocomplete to any HTML form with one script tag and one function call. No build step, no framework dependency.
Read guideValidate Email and Phone Before You Store Them
Most validation stops at syntax. Checkify checks MX records, SMTP deliverability, disposable providers, carrier names, line types, and formatting — so you store contact details that actually work.
Read guideScreen Customers Against Sanctions Lists
Check a name against 11 international sanctions and debarment lists with one API call. Fuzzy matching catches transliteration variants, confidence scoring reduces false positives, and birth details sharpen results.
Read guideLook Up Any Australian Entity by ABN or ACN
Not every entity is a company. Use the ABN endpoint to verify companies, sole traders, trusts, SMSFs, partnerships, and other entity types from the ABR. Use ACN for ASIC-registered company details like office addresses and document history.
