The GoCoin WooCommerce plugin is not available in the WordPress Plugin Directory yet, so we need to download it from GitHub and manually install it. Go to the plugin’s GitHub repo and download the zip file by clicking the Clone or Download button on the right side of the screen.
Login to your WordPress store and go to:
Dashboard » Plugins » Add New » Upload Plugin
Select the GoCoin WooCommerce plugin file which we downloaded in the previous step and install it. After installation is complete, activate the plugin.
After the GoCoin plugin is installed and activated, head over to
WooCommerce » Settings » Payments
Make sure GoCoin is an enabled payment method and then click on GoCoin.
The two empty fields are Merchant ID and API Key. You’ll get these from the GoCoin dashboard. Once you’re there, click the Developers icon.
Copy your merchant ID and click on Get API Key to obtain an API key from GoCoin. Copy and paste each of these to the appropriate fields in WordPress.
You’re done! Now you can start accepting Bitcoin Cash.
