Tessera — Support

Need help? Email joshdroberts2010@gmail.com and we’ll get back to you, usually within a couple of days.

Getting started

Tessera manages your own BrickLink store. On first launch you’ll be asked for four BrickLink API keys. To create them, sign in at bricklink.com → My Account → API → Register consumer, generate a consumer key, consumer secret, token value, and token secret, then paste all four into Tessera and tap Test & connect.

Common questions

“IP isn’t authorized” / connection fails. When you create the token on BrickLink, set its IP access to 0.0.0.0 (any IP) — a phone’s IP changes between cellular and Wi‑Fi, so a fixed restriction will block the app. Then double‑check the four keys were pasted correctly (Settings → Replace API keys).

How do I remove my keys? Settings → Disconnect wipes your keys from the device. Deleting the app removes all local data.

The widget is blank. Open the app once after connecting — it writes the snapshot the widget displays. The widget has no keys of its own.

Is my data sent anywhere? No. Tessera has no servers; your keys and store data stay on your device and are sent only to BrickLink. See the Privacy Policy.

Tessera is an independent app and is not affiliated with BrickLink or the LEGO Group.
