Property "Mobilenumber" does not have accessor method "getMobilenumber" in class "Magento\Customer\Api\Data\CustomerInterface".

Whenever i am trying to set customer custom attribute value i am getting above error. does anyone know how to save customer custom attribute value using REST API ?


i got the answer, you should have to use below code to update customer custom attribute

$customAttributeValues=array("attributeCode" => "mobilenumber", "value" => "918985552230");

$customerData = [
    'customer' => [
        'id' => 5,
        "email" => "test@example.com",
        "firstname" => "Magecomp",
        "lastname" => "Tester",
        "storeId" => 1,
        "websiteId" => 1,
        "customAttributes" => [$customAttributeValues],

$ch = curl_init("");
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($customerData));
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json", "Authorization: Bearer " . json_decode($token)));

$result = curl_exec($ch);
