⚠️ Note: The API Partner Program is a standalone offering and operates independently from the consumer RB2B platform at app.rb2b.com.
Overview
RB2B APIs gives developers and organizations direct access to RB2B's suite of Identity APIs — allowing you to build powerful integrations, enrich your existing identity graph, and take action on your website visitors in real time.
Access to the Identity APIs is not included with standard RB2B accounts of any tier.

Data, authentication, and usage within the API environment are fully isolated from consumer RB2B accounts.
