Apps

In Settings → Apps, workspace admins register custom applications, manage HTTPS webhooks for workspace events, configure OAuth client settings, and add branding and policy links for consent screens.

Members can see OAuth clients created automatically by tools such as CLI or MCP and revoke access when they no longer use the tool.

Custom apps

A custom app can receive webhooks, add Log in with One Horizon or Connect One Horizon, and call the API with user-approved access. Create one app for each product and environment, so production and staging keep separate webhook keys, callback URLs, and delivery logs.

Webhook delivery logs show recent attempts, status codes, and failures.

Agent-capable apps

An app can also expose an agent profile with a display name, optional avatar, active state, and capabilities. Agents and their sessions belong to that profile.

Building the app itself? Start with OAuth Apps for consent or Webhooks for event delivery. For agent harnesses, see Building Agents.

Billing

Upgrade, manage seats, download invoices, and cancel from Settings → Billing.

Preferences

Set your profile, locale, default workspace, coding tools, folders, launch behavior, and how completed initiatives and bugs roll into recap.

Custom app

Build a custom integration with OAuth apps, webhooks, the REST API, and the JavaScript SDK.

Compliance

Gather policy, contact, data handling, and security material for procurement and legal review.
