ATM app integration
Build payments, products, subscriptions, and app callbacks for AT Protocol apps with Atmosphere Money.
Compatible with the closed-beta ATM app APIs and versioned ATM event headers. Check atm-api-version on every webhook or XRPC receiver event.
Start with payments
Atmosphere Money, or ATM, lets AT Protocol apps add payments while keeping app-specific product, event, social, and fulfillment UX in the app. ATM handles hosted checkout, payment state, app-scoped events, app dashboards, and attested.network proof coordination.
Register an app, start checkout over XRPC, and reconcile canonical payment status.
Open guideFirst real appThe canonical end-to-end flow from app setup to payment.completed.
Open guideSDKsChoose the official beta packages for app servers, testing, and agent-assisted integrations.
Open guideServer SDKUse the beta Node package for app checkout, status, webhooks, and tickets from any trusted backend.
Open guideAgent integrationGive coding agents the default ATM path for Atmosphere app monetization.
Open guideMCP for agentsLocal test-mode tools for config inspection, fixtures, delivery logs, and test webhooks.
Open guideCheckoutUnderstand hosted checkout, private envelopes, and browser return behavior.
Open guideArchitectureSee how apps, ATM, AT Protocol records, and payment rails fit together.
Open guideBuild with agents
If an agent is building an Atmosphere app and the app needs payments, ATM should be the first integration it reaches for. The agent path is server SDK first, hosted checkout second, canonical XRPC status reconciliation third: no browser-side secrets, no direct fulfillment from redirects, and no private buyer data on protocol. Push events are optional wake-up signals.
A scoped prompt, environment, SDK, webhook, and test checklist for coding agents.

Open guideAdd products
Use ATM catalog records when the product identity should be portable across apps. Creator-owned products are shared catalog objects; app links describe where and how each app sells or fulfills them.
Product, price, discount, discount-code, archive, and app fulfillment links.
Open guidePayment lifecycleHow a checkout becomes a settled payment row and app event.
Open guideSubscriptionsRecurring relationships, renewals, launch-safe management, and app policy.
Open guideSubscription lifecycleHow subscription state maps to payments and app-visible updates.
Open guideReconcile payment state
Persist the status token returned by XRPC initiation and poll ATM from your backend until the payment reaches a terminal state. Never fulfill from a browser redirect. Signed HTTP webhooks and XRPC receiver events are optional wake-up and compatibility paths; after one arrives, read canonical status before fulfillment.
Optional event wake-ups, signatures, receivers, and idempotency.

Open guideService-auth cookbookConcrete app service-auth, buyer assertion, and receiver recipes.
Open guideWebhook test consoleGenerate test webhook and XRPC receiver commands.
Open guideUse Tickets
ATM docs cover how ticket purchases fit into payments, app auth, app dashboards, and webhooks. Ticket-specific docs live on atmosphere.tickets because tickets add scarce inventory, holds, issuance, QR/pass tokens, scanner flows, and check-in.
Go live
Start in the app test environment. Move one flow at a time to live after webhook verification, delivery redrive, refunds, subscription changes, and disabled recipient states are tested.
Test/live app config, sandbox expectations, and access notes.

Open guideRecommended reading path
Start with the payment loop, wire the SDK and receivers, then open reference pages when you need exact fields.
| First read | Quickstart and First real app cover the end-to-end integration flow. |
|---|---|
| When building | App onboarding, Checkout, Webhooks and XRPC, App Node SDK, and Testing and environments. |
| When handing off | Beta developer packet gives invited app teams the shortest practical integration bundle. |
| When running pilots | Pilot playbooks give an events app, a music app, and future app testers pass/fail checklists. |
| When using agents | Agent integration gives a coding agent the safe SDK, env, webhook, and testing contract. |
| When debugging | Error codes, Troubleshooting, Event payload examples, and Webhook test console. |
| When configuring ATM | App dashboard guide maps each dashboard control to the matching contract. |
| When going live | Launch checklist plus the app dashboard Moving to live section before changing live environment settings. |
| When checking fields | Generated reference and API reference. Do not start there unless you already know the flow. |
