Syeew — Lightspeed K-Series Integration

Setup guide: how to connect your Lightspeed K-Series POS to Syeew business intelligence.

Overview

The Syeew integration automatically pulls financial data from your Lightspeed K-Series POS — sales, refunds, per-line VAT, discounts, accounting categories, payment methods and restaurant data (covers, table, dine-in) — and centralizes it in Syeew for unified dashboards and reporting across all your locations. The sync runs automatically once a day; no manual export is required.

Prerequisites

  • An active Lightspeed K-Series account.
  • A Syeew account. If you don’t have one yet, request a demo on our website.
  • The Business Location ID of the venue you want to connect (optional — if not provided, the first available location is auto-detected).

Step 1 — Request access

  1. Contact Syeew at info@syeew.it to start the onboarding.
  2. Syeew requests a NO RIVAL Integration Hub account linked to your Lightspeed K-Series business. NO RIVAL is the certified partner that securely brokers authentication to the official Lightspeed K-Series API.
  3. You receive credentials (username and password) tied to your business.

Step 2 — Provide your details to Syeew

  1. Share the credentials with the Syeew team through a secure channel.
  2. Optionally provide your Business Location ID. If you leave it blank, Syeew auto-detects the first available location on your account.

No app installation is required inside Lightspeed. Authentication is handled by the NO RIVAL Integration Hub; there is nothing to install or activate from the Lightspeed back office.

Step 3 — Initial data load

  1. Syeew configures the integration and runs an initial historical backfill (up to 12 months) so your reporting starts with continuity.
  2. From then on, an automated sync runs every day and keeps your dashboards up to date.

What data is synced

  • Sales and refunds (refunds recorded as credit notes with negative amounts).
  • Per-line VAT rates, discounts and accounting-group categories.
  • Payment methods.
  • Restaurant detail: number of covers, table name, dine-in vs takeaway.

Only financial data is accessed. No customer personal data is required for the integration to work.

Multiple locations & accounts

Syeew supports multiple Lightspeed locations and multiple accounts. Data from every connected venue is consolidated in a single platform, so you can benchmark performance across your whole business.

Technical details (for developers)

  • Data endpoint: GET /f/finance/{businessLocationId}/financials/{from}/{to} (scope financial-api), include=payments,table.
  • Pull-based, no webhooks. Data is stored on Amazon S3 and loaded into Amazon Redshift; daily schedule at 03:00 UTC. Credentials are kept in AWS Secrets Manager.
