The Problem

Your product catalog lives in your ERP. Your sample program shouldn't duplicate it.

Most packaging companies manage thousands of products in their ERP. When it comes to sending samples, teams end up re-entering product data into spreadsheets, emails, or disconnected tools.

Every manual entry is a chance for errors, stale data, and mismatched inventory. SampleHQ’s ERP integration eliminates that — your catalog stays in your ERP, and SampleHQ stays in sync automatically.

How It Works

Three steps to a connected sample catalog

Generate an API key

One click in your SampleHQ workspace settings. Secure Bearer token authentication with rate limiting built in.

Sync your product catalog

Push products and inventory from your ERP to SampleHQ via REST API. Batch up to 100 items per request. SKU-based matching handles creates and updates automatically.

Get order updates back

Configure webhooks to receive notifications when orders are created, shipped, or delivered. HMAC-SHA256 signed payloads with automatic retry.

What Syncs

Products in. Orders out. Inventory aligned.

Your ERP remains the source of truth for your product catalog. SampleHQ keeps your sample program connected to it.

Product Catalog

Push product name, SKU, description, category, unit cost, and stock quantity. Upsert by SKU -- new products are created, existing ones updated. Archive products you no longer sample.

Inventory Levels

Sync stock quantities so your team knows what's available to send. Read current levels from SampleHQ or push updates from your ERP. Batch update up to 100 SKUs at once.

Order Webhooks

Receive signed webhook notifications when sample orders are created, status changes, shipped, delivered, or canceled. Includes customer details, tracking numbers, and timestamps.

Every webhook payload is signed. Verify authenticity before processing.

Automatic Retry

Failed webhooks retry with exponential backoff -- 30s, 2min, 10min, 1hr, 6hr.

Built-In Tools

Everything you need to set up, test, and monitor

One-Click API Key

Generate a secure API key from your workspace settings. Revoke and regenerate anytime.
