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.
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.

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.
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.

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.
Signature verification and security
How X-RR-Signature is computed, verification code for Node.js, Python and C#, guarding against replays, and how to replace a webhook secret.
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.
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.
