You need: admin access to your WordPress site. Connecting needs Starter or above. Applying a price to your store needs Premium or above.
Step 1. Create the API key in WordPress
- 1Log in to your WordPress admin.
- 2Open WooCommerce, then Settings, then Advanced, then REST API.
- 3Click Add key.
- 4Description: type CostCal Pro. User: choose your admin user. Permissions: choose Read/Write.
- 5Click Generate API key.
- 6Keep this page open. It shows the Consumer key (starts with ck_) and Consumer secret (starts with cs_) only once.
Step 2. Paste it into CostCal Pro
- 1In CostCal Pro open the Stores tab and choose WooCommerce.
- 2Store address: type the address your customers visit, for example https://yourstore.com. Your own domain or a subdomain both work.
- 3Paste the Consumer key and the Consumer secret.
- 4Click Connect store. We test the connection straight away.
If it does not connect
- The address must start with https and must open in a browser from outside your network.
- Permalinks must not be set to Plain. Set them to Post name under Settings, Permalinks.
- A security plugin or firewall may block the REST API. Allow requests to /wp-json/wc/v3.
