Magento 2 how to pass if exist search criteria in rest api call

Question

I need to filter getList records in my rest api call. I have following:

searchCriteria[filter_groups][0][filters][0][field]=city_ref&searchCriteria[filter_groups][0][filters][0][condition_type]=notnull

But it returns all records to me, even if city_ref isn't exist in the record. I need url parameter like above, because i pass it in ajax. How to do it?

Answer 1

I fount the solution. If you want to filter your request, your parameters should be like following:

searchCriteria[filter_groups][0][filters][0][field]=field_name&searchCriteria[filter_groups][0][filters][0][value]=&searchCriteria[filter_groups][0][filters][0][condition_type]=neq

So, value must be empty and filter must be 'neq'.
