Hubspot provides a REST API to create contact. In this example, we are going to create a contact using Hubspot Contact API. We are going to consume the rest api in PHP using curl

Prepare Contact data for sending

You need API Key before sending the request. Here is how you can get your HAPI Key. Create the contact information in an array.

define("HAPI_KEY", "dxxxxxe7-1xx3-4xx8-9bxx-6xxxxx8dd3xx");

$arr = array(
    'properties' => array(
        array(
            'property' => 'email',
            'value' => $email
        ),
        array(
            'property' => 'firstname',
            'value' => $fname
        ),
        array(
            'property' => 'lastname',
            'value' => $lname
        ),
        array(
            'property' => 'phone',
            'value' => $phone
        )
    )
);
$post_json = json_encode($arr);
$endpoint = 'https://api.hubapi.com/contacts/v1/contact?hapikey=' . HAPI_KEY;

Sending POST request to contact API

The create a new contact endpoint is used to create a new contact in HubSpot. The new contact will be assigned a unique ID (vid), which can be used to look it up later.

Use case for this endpoint: This endpoint can be used to perform a one-time sync of new contacts from an external system into HubSpot.

$ch = @curl_init();
@curl_setopt($ch, CURLOPT_POST, true);
@curl_setopt($ch, CURLOPT_POSTFIELDS, $post_json);
@curl_setopt($ch, CURLOPT_URL, $endpoint);
@curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
@curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = @curl_exec($ch);
$status_code = @curl_getinfo($ch, CURLINFO_HTTP_CODE);
$curl_errors = curl_error($ch);

@curl_close($ch);

$resp_json = json_decode($response);
$vid = $resp_json->vid;

• 200 OK : on success, which will include the details for the created contact
• 409 Conflict : if there is an existing contact with the email address included in the request. The response body will have the identityProfile details of the contact, which will include the vid of the existing record.
• 400 Bad Request: when there is a problem with the data in the request body, including when there are no properties included in the request data.

Add notes and engagement information to Engagement API.

To add additional information to the contact, we must call the Hubspot engagement API. Use this endpoint to create an engagement (an email, call, meeting, task or note) on an object in HubSpot.

// add note to contact
if(!isset($note)) {
    $note = '';
}
$arr = array(
    'engagement' => array(
        'active' => true,
        'ownerId' => 1,
        'type' => 'NOTE',
        'timestamp' => round(microtime(true) * 1000)
    ),
    'associations' => array(
        'contactIds' => array( $vid )
    ),
    'metadata' => array(
        'body' => $note
    ) 
);
$post_json = json_encode($arr);
$endpoint = 'https://api.hubapi.com/engagements/v1/engagements?hapikey=' . HAPI_KEY;
$ch = @curl_init();
@curl_setopt($ch, CURLOPT_POST, true);
@curl_setopt($ch, CURLOPT_POSTFIELDS, $post_json);
@curl_setopt($ch, CURLOPT_URL, $endpoint);
@curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
@curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = @curl_exec($ch);
$status_code = @curl_getinfo($ch, CURLINFO_HTTP_CODE);
$curl_errors = curl_error($ch);
@curl_close($ch);
