Fast Checklist (what we’ll do in this article)

• Ship deep links and intents so assistants can open precise screens and complete tasks in your app.
• Expose safe, idempotent action endpoints on web and mobile for add‑to‑cart, book, pay, and confirm.
• Harden auth and fraud controls for automation (PKCE, device binding, rate limits, step‑up checks).
• Instrument an “assistant funnel” in analytics and UTM tagging across Alexa.com, web chat, and in‑car.
• Update privacy/retention policies for assistant‑initiated actions and data deletion.

Why this matters now

On January 5, 2026, Amazon brought Alexa+ to the web, making a mainstream assistant available anywhere. At CES, agentic Android demos showed assistants tapping through apps, ordering rides, and editing settings on your behalf. Automakers are integrating assistants that can handle reservations and purchases from the dashboard. And on January 15, 2026, WhatsApp will block general‑purpose AI bots — shifting discovery and transactions to assistants on the web, in apps, and in cars.

Translation: assistants will hit your APIs and UI the way a power user would. If your deep links, intents, and action endpoints aren’t ready, you’ll miss revenue and introduce risk.

Part 1 — App readiness (Android and iOS)

1) Map 10 high‑value tasks and give each a deep link

Pick your top flows: sign‑in, reorder last purchase, add to cart, apply coupon, checkout, reschedule delivery, book slot, pay invoice, start return, track order. For each, ship a deep link/App Link/Universal Link that opens the exact screen with prefilled context:

app://cart/add?sku=ABC123&qty=2&coupon=JAN10&source=assistant_web

• Android: Android App Links + explicit intent-filter entries. Prefer HTTPS App Links when possible.
• iOS: Universal Links with apple-app-site-association configured and tested.

2) Expose App Actions (Android) and Shortcuts (iOS)

Make common tasks callable without brittle UI scripting. On Android, define App Actions and capability bindings so assistants can jump straight to actions; on iOS, add Siri Shortcuts/Intents for repeat tasks (e.g., “Reorder coffee beans”).

3) Auth that doesn’t break automation (but stops fraud)

• Support OAuth 2.1 + PKCE for web‑to‑app handoffs. Avoid SMS OTP as the only path.
• Bind sessions to device signals where possible; rotate short‑lived tokens (5–15 min) for high‑risk actions.
• Add step‑up verification only when risk is high: unusual device, new address, large order, or gift cards.

4) Make UI “agent friendly”

• Keep actionable elements above the fold; ensure primary buttons are uniquely identifiable and consistently labeled.
• Prefer single‑screen confirmations with an explicit summary: items, price, tax, delivery window, and terms.
• Provide a compact “Automation Mode” layout via a ?view=automation parameter to simplify flows when invoked by assistants.

5) Guardrails

• Rate limit by IP/device/account; add per‑minute and per‑hour ceilings for purchase, refund, and address changes.
• Idempotency keys on POSTs (Idempotency-Key) to prevent double charges during retries.
• High‑risk actions require an on‑device confirmation screen (no background charges).

Part 2 — Web and store readiness (Shopify/WooCommerce)

If an assistant lands on your site (via Alexa.com or in‑car browser), it needs structured data and clean actions — not popups.

1. Structured data: Ensure Product, Offer, AggregateRating, FAQ, and HowTo schema are present and valid.
2. Action endpoints: Provide documented HTTPS POSTs for cart, book, and cancel with idempotency and clear error codes.
3. Assistant UTMs: Tag sessions: utm_source=assistant with utm_medium values like alexa_web, in_car, android_agent.
4. Automations off WhatsApp: With the Jan 15 change, migrate conversational flows to web chat, email, and voice. Use our playbooks below.

Part 3 — Assistant analytics (measure what matters)

Instrument a distinct funnel for assistant‑driven sessions so you can prove revenue and fix drop‑offs fast.

• Source tagging: UTM taxonomy for alexa_web, android_agent, in_car, web_chat, email.
• Core events: assistant_session_started, intent_detected, action_invoked, action_result (success|fail|needs_user), order_placed, handoff_to_human.
• Diagnostics: Log input context (intent, parameters), response codes, latency, and idempotency key per transaction.
• Attribution: Use server‑side tagging for conversions to avoid blocked client scripts in in‑car browsers and assistant webviews.

Part 4 — Privacy, compliance, and retention

Agentic flows change your data surface: assistants may upload files, fill forms, and act across accounts. Keep it lawful and safe.

• Minimize and expire: Collect only the fields absolutely required to complete the action; set short retention for assistant‑uploaded data (e.g., IDs, prescriptions, invoices).
• User transparency: On confirmation screens, display what will be stored and for how long. Provide an inline link to delete or redact sensitive attachments.
• Access controls: Scope tokens narrowly; segregate assistant‑initiated actions so support teams can review without full account access.
• Deletion pathways: Honor “delete recent activity” and data subject requests quickly. Add a one‑tap purge for the last 24 hours of assistant‑initiated content.
• Incident readiness: Maintain an audit trail for actions taken by assistants; rehearse your patch/notify process.

Example: A mobile reorder flow via an Android agent

1. User says: “Reorder the coffee beans I bought last month.”
2. Assistant opens app://orders/reorder?order_id=12345&source=android_agent.
3. App calls POST /cart/reorder with Idempotency-Key; returns cart summary.
4. Assistant presents summary; user confirms.
5. App runs POST /checkout/pay with stored token; step‑up only if risk threshold is hit.
6. Emit action_result=success and order_placed; send receipt.

Result: zero typing, consistent guardrails, clean attribution to android_agent.

What to ship in 48 hours
