How to fill conversion page ?

[PubliAlex]

Hello,

I use this SDK to send form submissions to hubspot, it works, but I don't know how to fill the conversion page informations :

Here is my object :

                $data = [
                    'fields' => [
                        ['name' => 'email', 'value' => $formdata['Email']],
                        ['name' => 'firstname', 'value' => $formdata['Prénom']],
                        ['name' => 'lastname', 'value' => $formdata['Nom']],
                        ['name' => 'phone', 'value' => $formdata['Téléphone']],
                        ['name' => 'message', 'value' => $formdata['Message']],
                    ],
                    'legalConsentOptions' => [
                        'consent' => [
                            'consentToProcess' => true,
                            'text' => 'I agree to allow Example Company to store and process my personal data.',
                        ],
                    ]
                ];

any help would be much appreciated.

thank you
