Segment IP & Data Validation Integration
Validate IP and contact data automatically across Segment, so your team works from clean, verified records.
The 1Lookup Segment integration adds IP intelligence and contact validation to Segment. 1Lookup geolocates the IP behind a session, flags VPN, proxy, and datacenter traffic, and validates the phone and email on enriched profiles, so the events and segments in Segment reflect real users, not bots.
Why validate Segment data with 1Lookup
Segment is only as trustworthy as the data feeding it. 1Lookup validates the IP behind sessions (geolocation, VPN/proxy/datacenter detection) and the phone/email on profiles, so Segment segments and funnels are built on verified signals.
Enrich Segment events and user profiles with 1Lookup's IP and contact signals to filter bot/datacenter traffic, segment by real geography, and flag suspicious sessions.
What you can do
IP geolocation
Geolocate the IP behind Segment sessions: country, city, ISP, and ASN.
VPN / proxy / datacenter detection
Flag anonymised and bot traffic so Segment reporting reflects real users.
Contact validation
Validate the phone and email on profiles you enrich in Segment.
IP risk signals
Add IP threat and risk signals to Segment segments and rules.
How to connect 1Lookup to Segment
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.
Store the key securely
Keep the 1Lookup API key in your backend's secrets store (e.g. environment variables), not in client code.
Call the 1Lookup REST API
From your Segment workflow, send the IP, phone, or email to validate and read the clean JSON response.
Map and persist
Write the validated fields back into Segment for reporting and automation.
Use cases
Filter non-human traffic
Use 1Lookup VPN/proxy/datacenter detection to keep bot and anonymised sessions out of Segment reporting.
Trustworthy segmentation
Enrich Segment profiles with validated geo and contact data for cleaner cohorts.
Frequently asked questions
What does 1Lookup validate for Segment?
1Lookup adds IP intelligence for Segment (geolocation, ISP/ASN, and VPN/proxy/datacenter detection) plus phone and email validation on the profiles you enrich.
Do I need to write code to use 1Lookup with Segment?
Yes, this integration calls the 1Lookup REST API, so it suits developer workflows. You authenticate with an API key and map the JSON response into Segment.
Can I validate records I already have in Segment?
Yes. Alongside real-time validation, you can run existing Segment 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.
