Previewing a flow and testing it in the real app

Last updated: 22 October 2026 · 4 min read

A flow can be checked in two ways before it goes live: the builder's mobile preview and a test in the real app.

Steps

  1. 1

    Mobile preview

    Press the phone icon in the builder's header. The “Mobile preview” opens on the right: the builder's draft, unsaved changes included, drawn as the messenger draws it. Nothing is saved and nothing is sent. The icon is there only for a mobile app inbox's flows.

    • Tap buttons, fill in forms or type: the preview shows the next steps.
    • Clicking a step on the canvas starts the preview from it. “Start over” starts the flow again.
    • “AZ | EN | RU” switches the messenger's language, “Light | Dark” the theme.
    • At the end of a path it says “The flow ends here.”
  2. 2

    What the preview does not show

    • A “Condition” always takes “Otherwise”: there is no user.
    • {{…}} stays as written.
    • “Wait” does not wait.
    • The “Ask for a rating” card, Clomni AI's replies and the flow “Start another flow” opens are not shown.
    • If it does not load (“The preview could not be loaded.”), reload the page.
  3. 3

    Testing in the real app

    1. In the flow's “…” menu press “Duplicate”. The copy is a draft.
    2. Give the copy the “Manual” trigger, set it to “Active”, then “Publish”.
    3. Open the app on a test phone and start a new conversation.
    4. Open that conversation in the dashboard and send the copy with “Device” › “Send a flow” in the right panel.
    5. Walk the path in the app. Then pause or delete the copy.

    A “When a conversation starts” flow is tested by opening a new conversation, but an active, published flow reaches every user. Test with a copy first.

  4. 4

    If a change does not show

    • Was “Publish” pressed, and is the status “Active”?
    • A conversation already started goes on with the old version: open a new conversation in the app.
