Create Contact with Zoho Books API and PHP+Curl+Post Method

Hi everybody

I only want to add a new contact vía PHP + CURL + POST Method

I already have:
1) url = https://books.zoho.com/api/v3/contacts?
1) authtoken = XXXXXXX
2) organization_id = XXXXXXXX
3) JSONstring
{
      "contact_name": "Bowman and Co",
      "payment_terms": 15,
      "payment_terms_label": "Net 15"
}

Does anybody has an example?

Please!!!!
