Hello community.

I`m trying to create a custom object “Enfant” with API

Example of properties :

nom\_enfant (internal value / the kids name) - Nom de l’enfant (the human-readable property label)

prenom\_enfant (internal value)- Prénom de l’enfant (the human-readable property label)

But I get an error and I don’t know how to solve it … What should I write in “primary Display property” ?

Please advise.

Thank you and best regards.

Hi @Mathildehyp

Thank you for reaching out!

I noticed you’re probably using your HubSpot in French, I wanted to let you know that we have a FR Community you can access by changing your language in your settings via the language selector at the top left.

Regarding your API response, I want to tag some of our experts here - @Teun @himanshurauthan @miljkovicmisa do you know what could be happening here?

Thank you!

Best

Tiphaine

Hi [@TitiCuisset](https://community.hubspot.com/t5/user/viewprofilepage/user-id/89150) ,  
Your body of your request probably needs to look something like this:

```lia-code-sample
{
 "labels": {
 "singular": "Enfant",
 "plural": "Enfants"
 },
 "requiredProperties": [
 "nom_enfant"
 ],
 "searchableProperties": [
 "nom_enfant",
 "prenom_enfant"
 ],
 "name": "enfant",
 "primaryDisplayProperty": "nom_enfant",
 "secondaryDisplayProperties": [
 "prenom_enfant"
 ],
 "properties": [
 {
 "name": "nom_enfant",
 "label": "Nom de l'enfant",
 "isPrimaryDisplayLabel": true
 },
 {
 "name": "prenom_enfant",
 "label": "Prénom de l'enfant",
 "type": "string",
 "fieldType": "text"
 }
 ],
 "associatedObjects": [],
 "metaType": "PORTAL_SPECIFIC"
