The create contact API now returns the existing contact if the contact already exists.
We saw that many customers are creating WhatsApp and SMS contacts and immediately send a message using API. But the problem is that if the contact already exists, the API returns an error. The admin must always check if the contact exists before creating the contact.
Now you only need to create the contact, and if the contact exists, the API returns the existing contact. We added a new field, "contact_created" to allow you if the contact was created or an existing contact was returned.
