Webhook overview
Explains the main event types delivered by ReceiptRoller Webhooks, why to use Webhooks instead of polling, the delivery format (HTTPS POST + JSON), and how to think about delivery guarantees.
What You Can Do with the Developer Portal
An overview of what the ReceiptRoller developer portal lets you do. Combine data retrieval and operations via the REST API with real-time event delivery via Webhooks to connect store and user data from external systems.
Using the Sales API
An overview of ReceiptRoller's Sales API (/api/v1/sales/*) and how to filter by business account, store, POS terminal, and period. A getting-started guide covering the actual response structure (the KpiValue nested type) through averageTicket and the 8-hour token lifetime, for building a sales dashboard in an Android/iOS mobile app or server integration.
Available data domains
A one-page overview of the data domains you can retrieve from the ReceiptRoller developer portal. Summarizes the contents, retrieval methods, and required scopes for each domain — transactions, products, inventory, orders, customers, coupons, SNS, advertising, individual user data, and more.
Using the in-store media display API (Display API)
An overview of ReceiptRoller's in-store Android display API (/api/v1/displays/*) and the steps for pairing, heartbeat, playlist retrieval, and impression reporting. An introductory guide for building an app that plays a media loop on an Android kiosk or in-store signage device.
What is application registration
Explains the concept of ReceiptRoller application registration. Registering an app as an OAuth client issues a client ID, secret, and redirect URI, letting you start API and Webhook integrations.
Developer Help Index
The index of ReceiptRoller developer help. Covers the developer application, app registration, OAuth authentication and scopes, implementation guides (wallet apps, store-facing Webhooks, the Survey API), guides by data domain, operations and security, the community, and troubleshooting.
Inventory data integration
Explains the structure of ReceiptRoller's inventory data, multi-warehouse management, stock movement history, real-time sync via Webhooks, and WMS integration patterns.
How to read the API reference and docs
Explains the structure of ReceiptRoller's developer documentation and when to use each part. Covers the four entry points — the developer help, the API top page, the Swagger-based API reference, and the developer community — and how to obtain the OpenAPI spec (openapi/v1.json) for use with AI assistants and code generators.
How to register a Webhook
Explains how to register a Webhook endpoint in the ReceiptRoller developer portal, how to choose subscribed events, test delivery, using multiple endpoints, and how to delete or pause an endpoint.
Monitoring and handling failures
Explains how to read the ReceiptRoller Webhook delivery history, the metrics to monitor and how to design alerts, redelivering dead letters, and common failure patterns and recovery procedures.
Creating a new app
Explains the concrete steps to register a new app (OAuth client) in the ReceiptRoller developer portal. Covers the input fields, validation, the post-creation credentials display, and common errors.
Using the Transactions API (POS + OMS unified feed)
ReceiptRoller's Transactions API is a read-only API that unifies register sales (PosTransactions) and order-management orders (OmsOrders) into a single feed. It is the entry point for showing "all of a business account's transactions" as a list in an Android / iOS app.
Designing resends, ordering, and idempotency
Explains ReceiptRoller's Webhook resend policy, why delivery order is not guaranteed, implementing idempotency with event_id, handling dead letters, and common anti-patterns.
SNS Webhook bypass (forwarding Webhooks from external SNS such as LINE)
Explains the mechanism, setup, signature handling, and cautions of the "SNS Webhook bypass" feature, which forwards Webhooks ReceiptRoller receives from SNS platforms such as LINE to a developer app, with the store's consent.
Signature verification and security
Explains how ReceiptRoller Webhook HMAC-SHA256 signature verification works, sample verification code (Node.js / Python / C#), replay-attack countermeasures, and how to manage secrets safely.
Using the Products API
A guide to CRUD operations on products under a business account using the ReceiptRoller Products API (/api/v1/products). An introductory article for reading and writing the PIM (product master) from an Android/iOS app or server integration.
The flow to getting started
Explains the flow to start using the ReceiptRoller developer portal. If you register as a store user and are on the Starter plan or higher, no separate developer application is needed; you can register an app and begin API implementation right away.
Using the Staff API
A guide to CRUD operations on the staff (employees) under a business account using ReceiptRoller's Staff API (/api/v1/staff). Supports fields compatible with Square Team Member (name kana, multiple job assignments, and the pay structure).
Using the Orders / OMS API
A guide to CRUD operations on the orders under a business account using ReceiptRoller's Orders / OMS API (/api/v1/orders). Covers creating, updating, transitioning status (confirm, process, cancel), and deleting orders, plus the flow for Android / iOS apps and server integrations.
