PrestaShop 1.6 has several known issues that have been resolved in later versions of PS. Therefore, we strongly recommend upgrading to version 1.7 or a newer release of PrestaShop before using our connector.
If you still wish to use the 1.6 version, here is a brief overview of potential issues and their solutions.
Missing API for message objects in Webservice. Possible fix: https://drive.google.com/file/d/1_Fm9Y_kb5Bl7VnbBafoABdQkA9aPmA7D/view?usp=sharing
Technical note: This issue arises because PrestaShop developers did not implement the ability to read messages through API calls. However, our connector requires this API as it contains valuable information about orders. Comparison of Message.php in 1.7 and Message.php in 1.6 (the addon from the link above simply adds the missing parts).
Missing id_product_attribute for product_bundle attribute in API response. Possible fix: https://drive.google.com/file/d/1_Fm9Y_kb5Bl7VnbBafoABdQkA9aPmA7D/view?usp=sharing
Technical note: Prestashop developers in 1.6 forgot to add this important attribute to API. Because of this synchronization of Product Packs in 1.6 will not work. See comparison of Product.php in 1.7 and Product.php in 1.6. Above module adds this attribute to the API
Please note that we cannot guarantee that these fixes will work for every revision of PrestaShop 1.6. Additionally, we cannot guarantee that there are no other issues with older versions of PrestaShop.
