How to use 'searchCriteria' and 'fields' in REST API for fetch orders

Question

I am using below curl_init like this,

$webSiteUrl = 'mydomain.com'

$last2DayUpdated = date('Y-m-d',(strtotime ('-1 day', strtotime(date('Y-m-d')))));

$ch = curl_init("{$webSiteUrl}/rest/V1/orders?searchCriteria[filter_groups][0][filters][0][field]=updated_at&searchCriteria[filter_groups][0][filters][0][value]={$last2DayUpdated}&searchCriteria[filter_groups][0][filters][0][condition_type]=gteq");

But I want to fetch particular info like billing_address,customer_firstname,customer_lastname

For this, I need to use fields parameter.

But both parameters searchCriteria and fields are not working with each other. Only single parameter is working.

Anyone knows how can I use these both parameters together?

UPDATED:

I have tried as below, but not working.

$ch = curl_init("{$webSiteUrl}/rest/V1/orders?searchCriteria[filter_groups][0][filters][0][field]=updated_at&searchCriteria[filter_groups][0][filters][0][value]={$last2DayUpdated}&searchCriteria[filter_groups][0][filters][0][condition_type]=gteq&fields=billing_address,customer_firstname,customer_lastname");

Answer 1

I believe you need two different filters.

Not same API call but demonstrates how to do it

/magento/index.php/rest/V1/products/attributes?searchCriteria[filter_groups][0][filters][0][field]=attribute_code&searchCriteria[filter_groups][0][filters][0][value]=color&searchCriteria[filter_groups][0][filters][0][condition_type]=eq&searchCriteria[filter_groups][0][filters][1][field]=attribute_code&searchCriteria[filter_groups][0][filters][1][value]=size&searchCriteria[filter_groups][0][filters][1][condition_type]=eq

Although I've also just read online that there was a bug where didn't like this but it's been fixed since

Answer 2

According to the devdocs:

GET /rest/V1/orders? searchCriteria[filter_groups][0][filters][0][field]=status& searchCriteria[filter_groups][0][filters][0][value]=pending& searchCriteria[sortOrders][0][field]=increment_id& fields=items[increment_id,entity_id]

fields query parameter requires the items key which is array of fields you want to expose.
