Query · 1

apiKeystringRequired

Your BizKitHub API key (passed as GET parameter).

Key format: A 32-character string matching: ^(PROD|DEV_|ROOT)[A-Za-z0-9]{28}$
Prefixes: PROD (production key), DEV_ (individual developer), ROOT (system key with no limits). Learn more

Body · 3

emailstringRequired

Contact email address.

The system validates the input as a standard email address and automatically applies normalization and canonicalization.

All API responses return the normalized form, and each email address is unique per organisation within the system.

Phone-only contacts: Since 2026-06-10 a contact may exist without an e-mail when it was registered only by phone (e.g. imports of phone-only records). Responses that expose such contacts use API_EMAIL_NULLABLE instead, where this field can be null. Endpoints that accept e-mail as input still require a valid value here — phone-only creation goes through admin-only import / BFF flows.

passwordstringRequired

customerRealIpstring

User IP address used for GEO/IP intelligence.
Accepted formats: IPv4 (e.g. 1.1.1.1), IPv6 (e.g. 2001:4860:4860::8888)
Normalization:

::1, 0.0.0.0, localhost (or empty value) is normalized to 127.0.0.1
Invalid values are rejected (the API expects a valid IP string).

If provided, the system can resolve additional context (reverse DNS, geolocation, ASN, proxy/hosting flags) via our internal VikiTron GEO/IP resolver. Learn more
