WordPress Validation API Integration
Validate phone, email, and IP data automatically across WordPress, so your team works from clean, verified records.
The 1Lookup WordPress integration validates phone, email, and IP data for WordPress. 1Lookup checks phone line type and carrier, email deliverability, and IP risk (VPN, proxy, and fraud signals), then returns structured results so WordPress acts on verified, lower-risk data instead of guesswork.
Why validate WordPress data with 1Lookup
WordPress integrations call the 1Lookup REST API to validate phone, email, and IP data inline. Responses are clean JSON, so you can validate on submit, enrich records, and act on the result inside WordPress with minimal code.
Authenticate with an API key, send the value to validate, and map the structured response (line type, carrier, deliverability, IP risk) into WordPress. Use webhooks or batch endpoints for higher volume.
What you can do
Phone validation
Validity, line type, and carrier for every number flowing through WordPress.
Email verification
Deliverability plus disposable and role-based detection for emails in WordPress.
IP & fraud signals
Geolocate the IP and flag VPN/proxy and fraud risk on each WordPress record.
One REST API
Validate phone, email, and IP from WordPress through a single clean API.
How to connect 1Lookup to WordPress
Create a 1Lookup account and API key
Sign up for a free 1Lookup account and generate an API key from the dashboard. Free-tier lookups let you test before rolling out.
Connect 1Lookup to WordPress
Use a no-code automation platform such as Zapier or Make to link WordPress and 1Lookup, authenticating with your API key (or WordPress's own native automation if it offers one).
Map the field to validate
Point the automation at the phone or email field on the WordPress record you want to check.
Store results and branch
Write 1Lookup's response back to WordPress fields and branch your workflow on valid vs invalid.
Use cases
Validate at input
Call 1Lookup from WordPress on form submit or record create to reject invalid phone numbers and emails before they are stored.
Enrich and store
Persist 1Lookup's structured fields in WordPress so line type, carrier, and deliverability are queryable later.
Frequently asked questions
What does 1Lookup validate for WordPress?
1Lookup validates phone (validity, line type, carrier), email (deliverability, disposable/role-based), and IP (geolocation, VPN/proxy, risk) data. You choose which fields to store in WordPress.
Do I need to write code to use 1Lookup with WordPress?
No code is required. You connect 1Lookup to WordPress with a no-code automation tool such as Zapier or Make and map fields visually.
Can I validate records I already have in WordPress?
Yes. Alongside real-time validation, you can run existing WordPress records through 1Lookup batch validation and write the cleaned results back.
How long does setup take?
Setup is quick for most teams. The exact time depends on how many fields you map and whether you validate in real time, in bulk, or both.
