### Usage
Obtain the **ServiceEndpoint** url from the cloudformation stack output. This is the entry point to API Gateway for our app deployment and will be the root base URL for our API.
#### Get Price
`$ROOT_BASE_URL/api/v1/price/$PRODUCT_URL` - Get price for item. Example Usage:
`https://XXXXXXXX.execute-api.us-east-2.amazonaws.com/dev/api/v1/price/https%3A%2F%2Fwww.walmart.com%2Fip%2FParent-s-Choice-HMO-NonGMO-Sensitivity-Infant-Formula-4-Pack-33-2oz-ea%2F407822086`
* `$ROOT_BASE_URL` - ServiceEndpoint / API Gateway endpoint
* `$PRODUCT_URL` - URL of product to scrape price from. Must be URL encoded.
#### Get Product Details
`$ROOT_BASE_URL/api/v1/productDetails/$PRODUCT_URL` - Get details for item. Example Usage:
`https://XXXXXXXX.execute-api.us-east-2.amazonaws.com/dev/api/v1/productDetails/https%3A%2F%2Fwww.walmart.com%2Fip%2FParent-s-Choice-HMO-NonGMO-Sensitivity-Infant-Formula-4-Pack-33-2oz-ea%2F407822086`
* `$ROOT_BASE_URL` - ServiceEndpoint / API Gateway endpoint
* `$PRODUCT_URL` - URL of product to scrape details from. Must be URL encoded.
#### Watch item for price drop notifications
`$ROOT_BASE_URL/api/v1/watch` - Watch item for price drop. Expects `url` `priceThreshold` and `notificationPhoneNumber` as POST JSON input data:
* JSON input example: `{"url":"https://www.walmart.com/ip/Parent-s-Choice-HMO-NonGMO-Sensitivity-Infant-Formula-4-Pack-33-2oz-ea/407822086", "priceThreshold":PRICE, "notificationPhoneNumber":"5555555555"}`
