When to create a custom app

Custom apps are for tools your team already has that are not in the App Directory — an internal API, a niche SaaS product, or a homegrown system. Once built, a custom app behaves exactly like a normal app: it has tools, triggers, and connections.

Creating a custom app

  1. From the App Directory tap Create App.
  2. Give the app a name and a short description.
  3. Write Instructions describing when and how Zenning should use the app.
  4. Add one or more capabilities — each one represents an action Zenning can take. Provide the method, URL, headers, and any body parameters.
  5. Set permissions: choose whether the app is personal, attached to specific workspaces, or available to selected people.
  6. Tap Create to save — the app is now in your directory.

Editing a custom app

  1. Open the App Directory and filter to custom apps.
  2. Tap your app, then Edit.
  3. Change the name, description, instructions, or capabilities as needed.
  4. Save your changes — active employees will pick them up on the next run.
TipUse the capability preview to try your custom app before saving. It is much faster than publishing and finding an issue later.
