  6. 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

  1. 1In CostCal Pro open the Stores tab and choose WooCommerce.
  2. 2Store address: type the address your customers visit, for example https://yourstore.com. Your own domain or a subdomain both work.

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.
