How to declare response parameters of a server to string?

  api, javascript, php, wordpress

I have been working with an API where I’m calling it from a wordpress custom plugin. One of the response parameters that i need is Uid which is a long integer

This is what i’m getting on postmon and what is correct and i need to get this value on php too

But when I try to print same response on php it rounds the number somehow??

Here is what i get on php side which is wrong!

Im using wp_remote_post method from wordpress. I was thinking if there is a way to manually assign that Uid to string not integer to avoid rounding.

my Code:

    // Create new endpoint to get all products Data
add_action('rest_api_init', 'eos_store_rest_ajax_endpoint');

function eos_store_rest_ajax_endpoint()
            'methods'               => 'GET',
            'permission_callback'   => '__return_true',
            'callback'              => 'eos_store_rest_ajax_callback'

function eos_store_rest_ajax_callback()
    $url = "https://host:port/pospal-api2/openapi/v1/productOpenApi/queryProductPages";
    $response = wp_remote_post(
    'method' => 'POST',
    'headers' => array(
        'data-signature' => 'DATA-Signature',
        'time-stamp' => '1641903969',
        'Content-Type' => 'application/json;charset=UTF-8'
    'body' => json_encode(array( 'appId' => 'APPID' )),
    'cookies' => array()

    if (is_wp_error($response)) {
        $error_message = $response->get_error_message();
        return  "Something went wrong: $error_message";
    } else {
        return $response
