# Track supplement price drops and restocks

**Use case:** 

Checks a list of products on a schedule and reports only what changed: price drops, price rises, items going out of stock and coming back. Each result carries the recent price history with the lowest and highest price seen, so you can spot a genuine low rather than a small dip. Add a webhook URL to get alerted.

## About this Actor

This example demonstrates how to use [iHerb Scraper: Search, Products, Reviews & Monitor](https://apify.com/vaunted/iherb-scraper.md) with a specific input configuration.

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/vaunted/iherb-scraper.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
