sdk-ebay-rest-negotiation

The Negotiations API gives sellers the ability to proactively send discount offers to buyers who have shown an "interest" in their listings.

By sending buyers discount offers on listings where they have shown an interest, sellers can increase the velocity of their sales.

There are various ways for a buyer to show interest in a listing. For example, if a buyer adds the listing to their Watch list, or if they add the listing to their shopping cart and later abandon the cart, they are deemed to have shown an interest in the listing.

In the offers that sellers send, they can discount their listings by either a percentage off the listing price, or they can set a new discounted price that is lower than the original listing price.

For details about how seller offers work, see <a href="/api-docs/sell/static/marketing/offers-to-buyers.html" title="Selling Integration Guide">Sending offers to buyers.

sendOfferToInterestedBuyers Response is not JSON data error

Hi mate , working on it recently , whatever I try this requests wont be successful , Response is not JSON data most commonly
whenever I use $res = $apiInstance->sendOfferToInterestedBuyers($this->ebayId,$offerRequest,$contentType); or $res = $apiInstance->sendOfferToInterestedBuyers($this->ebayId,$jsonString,$contentType); where $jsonString = json_encode($offerRequest);
What I missing , generated json file match ebay requirements perfectly and all required fields are there . Any hint would be much appreciated. Emil

public function send_Ebay_Offers($params){

$contentType = 'Content-type:application/json';
    //$offer_duration = ['unit'=>DAY,'value'=>2];
    //$offered_price  = ['currency'=>'GBP','value'=>$params['offerPrice']];
    $offered_price = ['value' => $params['offerPrice']];

    foreach ($params['listing_IDs'] as $listingID) {
        $offeredItems = [['listingID' => $listingID, 'price' => ['value' => $params['offerPrice']], 'quantity' => 1]];

        $offerRequest = new \macropage\SDKs\ebay\rest\negotiation\Model\CreateOffersRequest();
        $offerRequest->setAllowCounterOffer($params['allowCounterOffer']);
        $offerRequest->setMessage($params['message']);
        $offerRequest->setOfferedItems($offeredItems);

       // var_dump($offerRequest);die();
        //$jsonString = json_encode($offerRequest);
        $apiInstance = $this->apiInstance;
        
        try {
            $res = $apiInstance->sendOfferToInterestedBuyers($this->ebayId,$offerRequest,$contentType);
            print_r($res);
        } catch (\macropage\SDKs\ebay\rest\negotiation\ApiException $e) {
            // Capture and decode the error response
            $errorResponse = $e->getResponseBody(); // Get the raw response body
            $errorDetails = json_decode($errorResponse, true); // Decode JSON response to an associative array
            echo "EMIL Error: " . $errorDetails['errors'][0]['message'] ?? 'Unknown error';
        } catch (\Exception $e) {
            // Handle other exceptions (if any)
            echo "EMIL Exception: " . $e->getMessage();
        }
    }
}
