Add a phone number to your Do Not Call (DNC) list.

When to use. Block a single number from being dialed. To approve or unapprove many numbers at once, or to create several in one call, use POST /dnc/mass.

Request body.

• phone (string, required): the phone number to add.
• approved (integer, required): approval status, 0 for unapproved or 1 for approved.
• country_iso (string): the two-letter country code (for example US) used to normalize the number.
• permanent (integer): whether the entry is permanent, 0 for no or 1 for yes. Defaults to 0 when omitted.

Returns. { "dnc": [ <entry> ] } with the created entry, and HTTP 201. Returns an error if an entry with the same phone number already exists.

Example. { "phone": "12125551234", "country_iso": "US", "approved": 1, "permanent": 0 }
