API Docs Unified API v2.0

API v1.0

We also offer another API version with endpoints that are easier to integrate. If you're a beginner in implementing API's you can switch to our v1.0 endpoint.

Query by full name - SPLIT FIRST AND LAST NAME

If you use a combined field for first and last name on your page, use this API to extract the parts:

Required Requests: 1
Content-Type: application/json
Authorization: Bearer <your authorization token>
JSON Payload
Field Type Required Description
full_name string Yes Name to query
country string No ISO 3166 ALPHA-2 Country Code
locale string No Browser Locale
ip string No Valid IPv4 or IPv6 address
id string No Max 50 chars. You can set this id to any alphanumeric value you want. As an example, you can set the id to your internal id of the dataset in your database. In an asynchronus environment this can help you to better connect the response to a previous request
