Hi
We're working with Mag V1.9.2.4 using SOAP API (...index.php/api/v2_soap...) with multiple websites and multiple storeviews.
We're able to insert and update products to provide default and storeview specific attribute values. This is done by firstly setting all attributes' default values by passing in empty storeview id to catalogProductUpdate. Then a second call to catalogProductUpdate passing in attribute values that are required to be storeview specific as non-null values with the corresponding storeview id. Magento's Admin pages show the storeview specific value and those attributes have "Use Default Values" unchecked. When catalogProductUpdate is called with a storeview id, attributes that have null values remain as default and their Admin pages shows "Use Default Value" checked.
Our problem is how to use the SOAP API to remove the storeview specific values from those attributes that have them so that their "Use Default Value" shows as checked.
We've tried passing null to those attribute values with the correct storeview id but this does nothing.
Internet searches (eg https://stackoverflow.com/questions/10313936/magento-set-product-attribute-to-use-default-values) suggest each storeview specific attribute value requires a boolean false value to revert it to "Use Default Values" but we are unable to do this with the SOAP API due to those attributes requiring String values.
Please advise how we can use the SOAP API to remove the storeview specific values from those attributes that have them so that their "Use Default Value" shows as checked.
