makenmarketing

This plugin allows you to designate certain products in your WooCommerce store to have no price. Instead, it displays a configurable button for customers to request a quote directly via a chat app (like WhatsApp).
From the settings page, you can customize: 
* The WhatsApp phone number. 
* The button text and icon. 
* The predefined message the customer will send. 
* The button colors.

Quote via Chat Button

Replaces the "Add to Cart" button with a chat button for products without a price, with customization options.

<li>Activate the Datafeedr Comparison Sets plugin through the ‘Plugins’ menu in WordPress.</li>
<li>Configure here: WordPress Admin Area > Datafeedr API > Comparison Sets.</li>

<ol>
<li>Go here WordPress Admin Area > Datafeedr API > Configuration > Amazon Settings.</li>
<li>Add your Amazon Access Key ID, Secret Access Key, Tracking ID and Locale.</li>
<li>Click the [Save Changes] button at the bottom of the page.</li>

<li>Change the Cache Lifetime field to <code>86400</code>.</li>
<li>Click the [Save Changes] button at the bottom of the page.</li>
</ol>
<h4>Display Comparison Sets for WooCommerce Products</h4>
To display comparison sets for products in your WooCommerce store, follow these instructions.
<ol>
<li>Go here WordPress Admin Area > Datafeedr API > Comparison Sets > Integrations.</li>
<li>Check the WooCommerce option.</li>

</ol>
Now, when a product in your store is viewed for the first time, a price comparison set will be generated.

<h4>Display Comparison Sets using Shortcodes</h4>
To display comparison sets in your posts, pages or in other areas where WordPress shortcodes are allowed, use the formats below.
Create a price comparison set using name field:
<pre><code>[dfrcs name="baratza encore"]
</code></pre>
Create a price comparison set using name and brand field:
<pre><code>[dfrcs name="j8006" brand="omega" ]
</code></pre>
Create a price comparison set with a custom title:
<pre><code>[dfrcs name="chaos harness" brand="black diamond" title="{num_products} great deals on Black Diamond Chaos Harnesses"]
</code></pre>
Available Filters
You can further filter the results of a Comparison Set by using the <code>filters</code> attribute. Available filters are:
<pre><code>currency
amazon_locale
image
onsale
direct_url
saleprice_min
saleprice_max
finalprice_min
finalprice_max
merchant_id
source_id
</code></pre>
Here is what each filter controls:
<pre><code>// Return only products which are priced in USD.
currency=USD

// Return Amazon products from US Locale.
amazon_locale=US

// Return only products that have an image.
image=1

// Return only products that are on sale.
onsale=1

// Return only products that have a direct URL.
direct_url=1

// Return only products with a minimum sale price of $10.
saleprice_min=10

// Return only products with a maximum sale price of $100.
saleprice_max=100

// Return only products with a minimum final price of $20.
finalprice_min=20

// Return only products with a maximum final price of $200.
finalprice_max=200

// Return only products from merchants with specific Merchant IDs (merchant_id).
merchant_id=61316,33092,97391

// Return only products from networks with specific Network IDs (source_id).
source_id=126,3
</code></pre>
Merchant IDs <code>merchant_id</code> (MID) and Network IDs <code>source_id</code> (NID) can be referenced on our <a href="https://datafeedr.me/networks" rel="nofollow ugc">Affiliate Networks & Merchants page</a>.
Here are some examples of how to use these filters in your shortcodes:
Create a price comparison set using <code>onsale</code> filter:
<pre><code>[dfrcs name="farpoint 55" brand="osprey" filters="onsale=1"]
</code></pre>
Create a price comparison set using currency filter:
<pre><code>[dfrcs name="aeropress coffee maker" brand="aerobie" filters="currency=USD"]

Create a price comparison set using multiple filters:
<pre><code>[dfrcs name="nomad 20 solar panel" filters="currency=USD&finalprice_max=400"]
</code></pre>

<pre><code>[dfrcs ean="737416080066"]
</code></pre>
Create a price comparison set using an Amazon ASIN code:
<pre><code>[dfrcs asin="B07BN6KH6W"]
</code></pre>
Create a price comparison set using an UPC code:
<pre><code>[dfrcs upc="050946872827"]
</code></pre>
Create a price comparison set limited to specific merchants and networks:
<pre><code>[dfrcs brand="patagonia" name="hoodie" filters="merchant_id=61316,33092,97391&source_id=126"]
</code></pre>
