Best practices for production operation
Explains best practices for running a ReceiptRoller integration app in production — environment separation, monitoring, deployment, incident response, and keeping documentation in order.
The basics of requests and responses (JSON)
Explains the request format, required headers, response structure, pagination, filtering, and date/time format rules of the ReceiptRoller API.
SLA, uptime, and the checking procedure during an incident
Explains ReceiptRoller's API uptime targets, how to check the status page, the isolation procedure when an incident occurs, and the flow for escalating to support.
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 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.
Monitoring and handling failures
Read a webhook's active flag, last delivery time and delivery log, notice when it has switched itself off, recover, and fill the gap from the API.
Rate limiting and throttling
Which ReceiptRoller API endpoints limit requests and by how much, what a 429 looks like, and how to pace and retry your client's calls.
Obtaining and refreshing an access token
How to obtain and refresh access tokens (8 hours) and refresh tokens (30 days), how refresh tokens rotate, and when tokens stop working.
Receive new sales by webhook and post them to Slack
Register a receipt.created webhook, verify its signature and drop duplicates in Node.js, and post each new sale to a Slack channel.
Designing resends, ordering, and idempotency
What counts as success, the retry rules (1 min, 10 min, 1 h, four attempts), ordering and lost events, and dropping duplicates by X-RR-Delivery.
Your first API call: from app registration to listing transactions
Get a token with the OAuth authorization code flow and PKCE, confirm the business account, list its transactions, and refresh the token.
Using the Products API
How to list, read, create, patch, replace, soft-delete and upload cover images for products with the Products API (/api/v1/products), with exact field names.
Connect an AI agent to ReceiptRoller over MCP
Connect Claude as an MCP connector, then build your own MCP client with dynamic client registration, PKCE and JSON-RPC calls over HTTP.
Webhook is not being delivered
When a webhook does not arrive: narrow it down with a test send and the delivery log, then check the active flag, subscribed events, connection and signature.
Sync your product catalogue with ReceiptRoller
Build a Node.js script that reads a local CSV or JSON file, matches products by SKU, and creates or patches them through the Products API.
How to register a Webhook
Register a webhook in the developer portal or through the API, choose events that are actually sent, run a test send, and change, pause or delete a webhook.
Wallet App: Guide to Fetching a User's Receipts via OAuth
Explains how to fetch a user's Receipt Roller purchase receipts, with their consent, from a wallet-style app such as iOS, Android, or a LINE Mini App. Covers OAuth 2.0 authentication, the receipts API, and Webhook integration.
Webhook overview
Which webhook events are actually sent, what the request and signature headers look like, how duplicates, order and lost events behave, and when to use the API.
Account linking and merging API (token exchange, /me/identities, /account/merge)
How native apps and the LINE mini app sign in with a LINE, Apple or Google ID token, add and remove sign-in methods, and merge two accounts — the endpoints, the proof object and the error codes.
Error codes and retry guidance
The status codes and error body shapes the ReceiptRoller API returns, token endpoint errors, and which failures to retry and how.
