This developer portal is the official integration documentation for Billabex. The public REST API exposes deterministic application workflows for accounts, contacts, invoices, credit notes, communications, and account tasks. The remote MCP server exposes Billabex capabilities as tools and resources for AI assistants. Both interfaces use the same OAuth 2.1 authorization server and named scopes so integrations can request only the permissions they need.
The canonical company website is www.billabex.com. Company news and identity are also available on the official Billabex LinkedIn page. For machine-readable integration details, use the OpenAPI specification, the MCP server manifest, and the agent instructions published by this portal.
