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.
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.
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.
OAuth Scopes Reference and Availability
A reference of all scopes available in the ReceiptRoller OAuth API and which kinds of apps each scope can be granted to. Also covers the review requirement for User scopes, why Store and User scopes can't be mixed, and how to use the API from a LIFF app.
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.
Creating a new app
How to register a developer app in a business account: the fields, how the credentials are shown, what you can do afterwards, and common stumbling points.
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.
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.
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
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.
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.
Show a store's reservations in your own calendar
Fetch the next 7 days of a store's reservations with the Reservations API and write them to an iCalendar (.ics) file with Node.js.
Setting the redirect URL
The role of the single redirect URI on a developer app, the exact-match rule, separating environments, changing it, and common errors.
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.
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.
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.
403/401 is returned (permissions and scopes)
How to isolate the cause when an API call returns 401 or 403. Explains the typical cases: invalid token, insufficient scope, no store access permission, and User-scope review not passed.
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.
Listing business accounts, stores, and POS terminals
A guide to retrieving, via REST API, the business accounts a user belongs to, the stores under them, and each store's POS terminals, from a ReceiptRoller mobile app or server integration.
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.
