Test on your phone — IngevoraMirage

Test on your phoneTest on phone shows the draft of a face lens on a real phone, over its front camera, before you publish. The phone follows your edits as you make them. Nothing is published, and no app receives the draft.Test on phone is for face lenses. A screen effect plays in the studio's own phone-screen viewer instead.Start a test

Open the face lens in the studio.

Choose Test on phone in the header. The editor saves your pending edits first.

The dialog shows:

a QR code;
the address of the phone test page, with Copy;
a second link under "For debug app builds";
a countdown, "Expires in …";
Issue a new link.

On the phone

Scan the QR code with the phone's camera and open the page.

Tap Start camera and allow the camera.

The page draws the draft over the front camera, mirrored like a selfie view.

A "TEST — draft" banner shows the time left. Below the picture, a button for each host event the lens listens to lets you send that event. Face triggers react to your own face: open your mouth, smile, blink.You don't sign in on the phone. Tracking and drawing happen on the phone, and the camera picture is not uploaded.It follows your editsThe page checks for a new draft every 3 seconds. When the draft changes, the lens restarts on the phone and the page says "Draft updated".

If an edit leaves the draft broken, the page keeps showing the last good draft, with a banner, until you fix it.

If the phone loses its connection, the page says "Offline, retrying…" and keeps trying.

30 minutes, then a new linkA link works for 30 minutes from when you issue it. Editing doesn't extend it, and it can't be renewed.

When it runs out, the dialog says "This link has expired." and the QR code goes away.

The phone page stops the camera and says the link has expired.

Choose Issue a new link for a fresh one. An older link keeps working until its own time runs out.

What a test needs

The draft needs at least one layer, and its structure must be valid. If it isn't, the dialog says what to fix.

Other issues don't stop a test. A missing image, or a layer in a keep-out zone, is fine while you work; Publish still checks everything.

Archived lenses can't be tested.

Owners and Designers can test. For Developers the button is turned off.

Only published versions reach appsA test link shows the draft to whoever opens it. It never changes what apps receive: the delivery API serves published versions only. When the lens looks right on your phone, choose Publish. See Versions, latest and pinned.

Important: Anyone who has the link can see the draft until the link expires. Share it only with people who should see unpublished work.

For debug app buildsThe link under "For debug app builds" is an API address:

bash

curl https://mirage-api.ingevora.com/v1/test-links/<token>

It needs no API key: the token in the address is the credential. The answer holds the lens id, the draft's manifest as the next publish would write it, a map from each image name to its URL, and the time the link expires. It answers 410 once the link has expired, 404 for a link that isn't valid, and 429 when one address asks more than 120 times a minute.If you build your own loader, follow these rules:

Accept test links in debug builds only, never in a release build. They carry unpublished work.

Don't cache the answer. Fetch it again on every load, so you always see the latest edit.

Show that a draft is running, for example with a "TEST — draft" label.

Check each image against the sha256 the manifest gives it, as you would for a published version. See Downloading safely.
