Email verification for CI — generates an isolated inbox per run. OTPs and magic links auto-extracted at Cloudflare's edge. No Docker, no SMTP, no signup.

- uses: zerodrop-dev/setup-zerodrop@v1
  id: mail

- run: npx playwright test
  env:
    TEST_INBOX: ${{ steps.mail.outputs.inbox }}

That's it. Every workflow run gets a fresh, isolated inbox. Parallel jobs never collide.

1. setup-zerodrop generates a unique inbox — locally, no network request
2. Your app sends real verification emails to it
3. ZeroDrop catches them at Cloudflare's edge — OTPs and magic links auto-extracted
4. Your tests read them via any ZeroDrop SDK: email.otp, email.magicLink

steps:
  - uses: actions/checkout@v4

  - uses: zerodrop-dev/setup-zerodrop@v1
    id: mail

  - uses: actions/setup-node@v4
    with:
      node-version: 20

  - run: npm ci
  - run: npx playwright install --with-deps chromium
  - run: npx playwright test
    env:
      TEST_INBOX: ${{ steps.mail.outputs.inbox }}

Tag inboxes by app or job for easier debugging:

- uses: zerodrop-dev/setup-zerodrop@v1
  id: mail
  with:
    prefix: myapp
# → myapp-swift-x7k29ab@zerodrop-sandbox.online

The action also exports env vars — no steps.<id>.outputs wiring needed:

- uses: zerodrop-dev/setup-zerodrop@v1

- run: npx playwright test
  # $ZERODROP_INBOX and $ZERODROP_INBOX_NAME are already set

- uses: zerodrop-dev/setup-zerodrop@v1
  with:
    api-key: ${{ secrets.ZERODROP_API_KEY }}
# Exports ZERODROP_API_KEY for your test steps

Free sandbox mode needs no key. Workspaces add custom domains and extended retention.

Use any ZeroDrop SDK inside the test step:

import { ZeroDrop } from "zerodrop-client";

const mail = new ZeroDrop();
const inbox = process.env.TEST_INBOX!;

const email = await mail.waitForLatest(inbox, { timeout: 15000 });

email.otp        // "847291" — auto-extracted, no regex
email.magicLink  // "https://..." — auto-extracted

Pin to a commit SHA instead of a tag:

- uses: zerodrop-dev/setup-zerodrop@<commit-sha>  # v1

The action is a single dependency-free dist/index.js — auditable in one read. Inbox generation is fully local; the action makes no network requests.

This action was previously published as zerodrop-dev/create-inbox. That path was retired by GitHub during an account migration. Update your workflows:

- - uses: zerodrop-dev/create-inbox@v1
+ - uses: zerodrop-dev/setup-zerodrop@v1

Inputs and outputs are unchanged, plus new api-key and base-url inputs.
