Developer front door
Build with B5 Secure
Build with B5 Secure is the working front door for developers integrating B5 trust controls into APIs, applications, mobile clients, browser extensions, partner services, and on-premises systems.

Implementation steps
Open Start Here and record the identifiers and ownership fields required for your integration.
Configure an isolated Test Mode environment and import the downloadable Postman assets.
Complete the Quick Start, then move to the platform-specific guide.
Use the release checklist before requesting staging or production access.
Build with components you can open, run, and inspect
The Build hub now includes executable reference clients, signed-request examples, Test Mode assets, native-client starting points, webhook verification, and release gates. Endpoint and credential values remain explicit placeholders until issued for a B5 environment.
