Typeform Validation API Integration
Validate phone, email, and IP data automatically across Typeform, so your team works from clean, verified records.
The 1Lookup Typeform integration validates phone, email, and IP data for Typeform. 1Lookup checks phone line type and carrier, email deliverability, and IP risk (VPN, proxy, and fraud signals), then returns structured results so Typeform acts on verified, lower-risk data instead of guesswork.
Why validate Typeform data with 1Lookup
Wiring 1Lookup into Typeform gives your application real-time validation of phone numbers, emails, and IPs through a clean REST API. Instead of shipping bad data, Typeform can verify input at the source and store structured results.
Authenticate with an API key, send the value to validate, and map the structured response (line type, carrier, deliverability, IP risk) into Typeform. Use webhooks or batch endpoints for higher volume.

How to connect 1Lookup to Typeform
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 Typeform
Use a no-code automation platform such as Zapier or Make to link Typeform and 1Lookup, authenticating with your API key (or Typeform's own native automation if it offers one).
Map the field to validate
Point the automation at the phone or email field on the Typeform record you want to check.
Store results and branch
Write 1Lookup's response back to Typeform fields and branch your workflow on valid vs invalid.
Use cases
Validate at input
Call 1Lookup from Typeform 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 Typeform so line type, carrier, and deliverability are queryable later.
Frequently asked questions
What does 1Lookup validate for Typeform?
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 Typeform.
Do I need to write code to use 1Lookup with Typeform?
No code is required. You connect 1Lookup to Typeform with a no-code automation tool such as Zapier or Make and map fields visually.
Can I validate records I already have in Typeform?
Yes. Alongside real-time validation, you can run existing Typeform 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.
