Installation manual for the WooCommerce Twinfield integration

Updated today

Connect WooCommerce with Twinfield and automatically process webshop orders in your accounting. Ideal for WooCommerce entrepreneurs and accountants using Twinfield.


1. Connect to WooCommerce

To connect to WooCommerce, you need an API key and API secret.

Connect to WooCommerce

  1. Log in to your WordPress environment.

  2. In the WooCommerce plugin, go to Settings.

  3. Click on Advanced, then select REST API.

Creating an API Key

  1. Click Add key to create a new API key.

  2. Enter a description, for example, Combidesk.

  3. Select the desired user.

  4. Under Permissions, choose Read/Write.

  5. Save the key and note both the API key and API secret, as you will need them later for the integration.

Setting Pretty Permalinks

To use the WooCommerce API, your WordPress environment must have pretty permalinks enabled.

  1. Go to Settings → Permalinks in WordPress.

  2. Check that the permalink structure is not set to Plain.

    • If it is already set to something other than Plain, no changes are needed.

    • If it is set to Plain, choose a different structure from the list (for example, Post name). Confirm this with your website administrator.

  3. Save the settings.

Updating WordPress and WooCommerce

It is recommended to update both your WordPress environment and the WooCommerce plugin to the latest version.

  • This prevents compatibility issues when using the API.

Frequently asked questions

My login credentials don't work — what now?
