***
To make a WooCommerce catalog page work with a CheckoutChamp shopping cart, you will add links to your checkout page Add To Cart buttons.\
\
The links will have the productId parameter in the query string equal to the desired CheckoutChamp campaign product ID.
Examples:
a link
```
Add to Cart
```
a button img
```
```
The link will take you to the checkout page with that product added to the shopping cart with quantity 1.
**This method is intended to be used with a separate checkout page than your WooCommerce checkout page.**
### Direct API -
You’ll need to add this script to the page parse the input and cache the products into the product array-
```javascript
const urlParams = new URLSearchParams(location.search);
if (urlParams.has("products")){
const urlProducts = urlParams.get("products").split(";");
for(const product of urlProducts){
const pos = product.indexOf(".");
const splitChar = pos > 0 && pos < product.indexOf(":") ? "." : ":";
const productData = product.split(splitChar);
myCart[productData[0]] = productData[1];
}
sessionStorage.setItem("myCart",JSON.stringify(myCart));
}
```
When making the Import Order API call, parse myCart into product{i}\_id, product{i}\_qty, and variant{i}\_id (if applicable). Increment {i} for each product, starting with 1.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://help.checkoutchamp.com/crm/plugins/data-sources/woocommerce/using-woocommerce-catalog-with-checkout-page.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.

The link will take you to the checkout page with that product added to the shopping cart with quantity 1.
