Hi, @krotons.

The [v1 Products API](https://developers.hubspot.com/docs/methods/products/create-product) expects a single array in the payload. Here’s the example from the documentation:

```auto
[
 {
 "name": "name",
 "value": "A new product"
 },
 {
 "name": "description",
 "value": "A description of this product."
 },
 {
 "name": "price",
 "value": "27.50"
 },
 {
 "name": "recurringbillingfrequency",
 "value": "quarterly"
 }
]

```

If you remove the `{}` and the `"properties":` key, you should receive a successful response.

Hi I am too facing the same error  
“Invalid input JSON on line 1, column 132: Cannot deserialize value of type `java.util.ArrayList` from Object value (token `JsonToken.START_OBJECT`)”  
Where I am passing the json through curl request below is the following json  
{  
“name”: “DEMO\_NAME”,  
“label”: “Demo Property”,  
“type”: “enumeration”,  
“field\_type”: “select”,  
“group\_name”: “contactinformation”,  
“options”: {  
“label”: “Danzig”,  
“value”: “Danzig”  
},  
“display\_order”: 2,  
“has\_unique\_value”: false,  
“hidden”: false,  
“form\_field”: true  
}  
and this is my curl request code

$ch = @curl\_init();

@curl\_setopt($ch, CURLOPT\_POST, true);  
@curl\_setopt($ch, CURLOPT\_POSTFIELDS, $json);  
@curl\_setopt($ch, CURLOPT\_URL, $endpoint);  
@curl\_setopt($ch, CURLOPT\_HTTPHEADER, array(  
‘Content-Type: application/json’  
));  
@curl\_setopt($ch, CURLOPT\_RETURNTRANSFER, true);  
$response = @curl\_exec($ch);  
print\_r($response);  
exit;  
$status\_code = @curl\_getinfo($ch, CURLINFO\_HTTP\_CODE);  
$curl\_errors = curl\_error($ch);  
@curl\_close($ch);  
echo “\<br\>”;

print\_r($response);  
if($response)  
{  
echo “Property Created”;  
echo “\<br\>”;  
return $response . "  
";  
$result = file\_get\_contents($response);  
var\_dump(json\_decode($result, true));  
}  
echo “\<br\>”;

}

Please help me out in this with a helpful solution

i’ve same problem in php?

{“status”:“error”,“message”:“Invalid input JSON on line 1, column 1: Cannot deserialize value of type `com.hubspot.inbounddb.publicobject.core.v2.SimplePublicObjectInputForCreate$Json` from Array value (token `JsonToken.START_ARRAY`)”,“correlationId”:“b292d6c5-55a4-4d5f-b386-875453f88bf1”}

` `

here is my code:

\<?php

if ($\_SERVER[“REQUEST\_METHOD”] == “POST”) {

// Check if the ‘name’, ‘email’, and ‘phone’ keys exist in the $\_POST array

if (isset($\_POST[“name”]) && isset($\_POST[“email”]) && isset($\_POST[“phone”])) {

// Retrieve form data

$name = $\_POST[“name”];

$email = $\_POST[“email”];

$phone = $\_POST[“phone”];

// Perform any validation or processing here

// Prepare data to be sent to the API

$data = array(

[

[‘name’ =\> ‘name’, ‘value’ =\> $name],

[‘name’ =\> ‘email’, ‘value’ =\> $email],

[‘name’ =\> ‘phone’, ‘value’ =\> $phone]

]

);

$data\_string = json\_encode($data);

// API URL

$api\_url = ‘[https://api.hubapi.com/crm/v3/objects/contacts](https://api.hubapi.com/crm/v3/objects/contacts)’;

$access\_token = ‘pat-na1-7618b06c-b2ad-4cd6-9c41-55efa0116a38’; // Replace with your actual access token

$response = curl\_exec($ch);

if (curl\_errno($ch)) {

echo 'Error: ’ . curl\_error($ch);

} else {

// Process the API response here (e.g., display or save it)

echo “API Response: \<pre\>” . $response . “\</pre\>”;

}

curl\_close($ch);

} else {

// Handle the case where one or more form fields are missing

echo “One or more form fields are missing.”;

}

} else {

// Handle the case where the page is first loaded

// You can optionally display the form here
