State code to update the customer address from API

Here we are mentioning to set the state code from the country code and state id from the Netsuite API.

We are getting the state and country through the response/params from the API

    $resultJson = $this->_resultJsonFactory->create();
    $params = $this->getRequest()->getContent();
    $writer = new \Zend_Log_Writer_Stream(BP . '/var/log/Address_update.log');
    $logger = new \Zend_Log();
    $logger->addWriter($writer);
    $response = array(
        'status' => 500,
        'message' => 'Error, Please try again',
        'params' => $params
    );
    if(!empty($params)) {
        $addresss=$params;
        $addresss= json_decode($addresss,true);
        $logger->info(print_r($addresss,true));

//setting the state from country code and state code
        if(!empty($addresss)){
            $region=$addresss['State'];
    if($region){
            $regionCode = $this->collectionFactory->create()
                ->addRegionCodeFilter($region)
                ->addCountryFilter($addresss['Country'])
         ->getFirstItem()
                ->getData('region_id');

            $logger->info($regionCode);
    }
            $address = $this->addressfactory->create()->load($addresss['id'],'entity_id');
            $logger->info($addresss['id']);
            $logger->info($address->getEntityId());
            if($address->getEntityId() == $addresss['id']){
                $address->setCustomerId($addresss['customer_id'])
                    ->setFirstname($addresss['firstname'])
                    ->setLastname($addresss['lastname'])
                    ->setCountryId($addresss['Country'])
                    ->setPostcode($addresss['Post_Code'])
                    ->setCity($addresss['City'])
                    ->setTelephone($addresss['telephone'])
                    ->setStreet($addresss['street']);
                    if($regionCode){
                    $address->setRegionId($regionCode);
                    }
                if($addresss['set_is_default_shipping'] == 1){
                    $logger->info("default_shippping");
                    $address->setIsDefaultShipping(1);
                }
                if($addresss['set_is_default_billing'] == 1){
                    $logger->info("default_billing");
                    $address->setIsDefaultBilling(1);
                }
                $address->save();
                $response = array(
                    'status' => 200,
                    'message' => 'Customer Address Updated',
                    'params' => $params
                );
            }
