Integration · Resend

Send the photo by email

Resend is the service that emails the photo to a guest. You bring the account. The tablet keeps the API key on-device and calls Resend’s HTTP API when a guest taps the email button. The photo rides as a JPEG attachment, so the email is self-contained.

1

Create a Resend account

Sign up at resend.com. Verify your email when asked.

2

Verify a sending domain

In the Resend dashboard, open Domains, then Add Domain. Enter a domain you own (for example, snapcabin.example.com). Resend will list a handful of DNS records (SPF, DKIM, sometimes DMARC). Add them at your DNS provider and wait for Resend to mark the domain as Verified — this usually takes a few minutes.

If you’re just trying things out, skip this step and use onboarding@resend.dev as the From address. Emails will send but will arrive from a generic Resend address.

3

Create an API key

Open API Keys, then Create API Key. Give it a name like snapcabin-kiosk and set permission to Sending access (so it can send mail but not change account settings). Copy the key — it starts with re_ and is shown only once.

The API key lets anyone with it send email as your account. Treat it like a password. SnapCabin stores it in the tablet’s private app data and never sends it anywhere besides Resend. If the key leaks, revoke it in the Resend dashboard and create a new one.

Enter the credentials on the tablet

On the tablet:

  1. Long-press the bottom-right corner of the Attract screen.
  2. Enter the admin PIN. (Default is 1234. Change it before your event.)
  3. Open EMAIL DELIVERY and turn on “Enable email delivery via Resend”.
  4. Paste the API key and a From address. The From address should look like SnapCabin <booth@yourdomain.com> using a domain you verified in step 2.
  5. Optionally adjust the subject line, the per-session cap, and the per-address cap.

Test by sending to your own inbox

End the current event (or start a fresh test event), capture a photo, tap EMAIL, and enter your own email address. The photo should arrive within a few seconds. If something goes wrong, the tablet shows the Resend error on screen and writes it to the Audit Log section.
