Wordpress Hook for only order processing

Question

I am making a WordPress plugin, where I need to make an API call every time order status updates to "processing" from "pending".

    function __construct(){
        add_action( 'woocommerce_after_order_object_save', [$this,'action_woocommerce_doba_order_import'], 10, 1 ); 
    }

    public function action_woocommerce_doba_order_import($order){
            
        if ( 'processing' === $order->get_status() ) {
           "API call here" 
        }
            
    }

This code works fine when order status updates to "processing" from "pending" but it makes two additional API calls when status changes to something else from "processing". So I get two additional API calls for each order it status changes from processing to something else. I am definitely making some mistakes. Maybe I am using the wrong hook or need to put a different condition.

We have created a WordPress code for changing the order status, Hooks function call every time order status updates to "processing" from "pending".

You try this:

  function __construct(){
            add_action( 'woocommerce_after_order_object_save', [$this,'action_woocommerce_doba_order_import'], 10, 1 ); 
        }
    
        public function action_woocommerce_doba_order_import($order_id){
                
        if( ! $order_id ) return;
    
        $order = wc_get_order( $order_id );
    
        if( $order->get_status() == 'pending' ) {
            $order->update_status( 'processing' );                
        }

}

I tried to find this action in the newest version of the WooCommerce plugin [6.3.1] and I couldn't, but I found out that there's probably a better hook to use, which includes the new status.

do_action( 'woocommerce_order_edit_status', $this->get_id(), $result['to'] );

So you could use it like this:

function __construct(){
            add_action( 'woocommerce_order_edit_status', [$this,'action_woocommerce_doba_order_import'], 10, 2 ); 
        }
    
        public function action_woocommerce_doba_order_import($order_id, $new_status){
                
        if( ! $order_id ) return;

        //ignore other status changes without additional calls
        if( 'pending' !== $new_status ) return;

        $order = wc_get_order( $order_id );

}
