This was extremely helpful, thanks.
The only thing I needed was to add a “&” after my consumer_secret while encoding, and now it works like a charm.

Thank you again!

Thank you for the reply!
In the end I resolved by modifying wordpress to work like it’s advertised on the documentation.
If anyone is interested in how to do it, here are some easy steps:
– Locate your woocommerce installation folder. Should be in “www.your.site/wp-content/plugins” and search for a folder named “woocommerce”.
– Find class-wc-api-products.php in “woocommerce_folder/includes/api.
– Open it and go around line 1053. You’ll find something like this:

// Product categories
		if ( isset( $data['categories'] ) && is_array( $data['categories'] ) ) {
			$terms = array_map( 'wc_clean', $data['categories'] );
			wp_set_object_terms( $product_id, $terms, 'product_cat' );
		}

– You just need to replace “wc_clean” with “intval” and the job is done!

NOTE: I’m using WooCommerce 2.3.11.
