Hi, Habib!
Julie here from Shopify Support. Thanks for reaching out.
Adding a WhatsApp sharing button to your products pages can easily be done using an app like Social Sharing Buttons or Fancy Social Sharing. Both these apps will allow you to add social media sharing links to your product pages and give you the ability to customize the style, position, size, and colour of your buttons. Aside from WhatsApp buttons, these apps also include buttons for other social media platforms like Facebook, Instagram, Snapchat, Tumblr, Pinterest, and more. I recommend checking out both these apps to see which one you like the best. If you ever require any support with either of these apps, you can always contact the developers directly via the Support section on their app pages.
To address your question about a direct download button, what kind of files are you wanting your customers to download? Have you already uploaded the file in your Shopify Admin? Depending on whether you want your resellers to access the download before or after a purchase, there are a few of ways you could do this.
First, if you’d like to give your resellers the ability to download their file directly from the product page without making a purchase, then you could simply add a hyperlink to some text in your product description. This wouldn’t necessarily look like a button, but it would still give your resellers the ability to download the file. This is a pretty straightforward and simple solution, but if you’re specifically looking for a button, then one of the following options would suit your needs a bit better.
Second, you could use an app like ShopShare, which will allow you to attach digital files to any product or page. With ShopShare, you can also customize your buttons so that it matches the look and feel of your store. It also provides you with analytics, so you can see how many users are downloading your files. Some file types that you can use include videos, audio, documents, images, and more. If you’re simply looking to have a button on your product page that anyone can download from, then I would definitely recommend this app.
Alternatively, you could use Shopify’s Digital Downloads app. This app will allow you to create a digital product that your resellers can purchase (you can also make this product free). After they complete the checkout, they’ll be automatically directed to a Thank-You page, where they’ll see a download button. They’ll also automatically receive an email post-purchase that includes the download link. Just keep in mind that this method would require your resellers to go through the checkout process.
I hope this provides you with a few good options, and I’m curious to know what you think. I’d also love to learn more about your business and the types of downloads your looking to offer your resellers.
Looking forward to hearing from you!
