cURL POST request using variables

I am trying to set up a basic code to insert some customers into a our customer support software without having to go in and do each one manually. I seem to be having issues when I introduce variables into the code.

This code works:

#!/bin/sh
curl https://yoursite.desk.com/api/v2/customers \
-u username:password \
-X POST \
-H "Accept: application/json" \
-H "Content-Type: application/json" \
-d '{
    "first_name":"John",
    "last_name":"Doe",
    "phone_numbers":
      [
        {
          "type":"Other",
          "value":"5555555555"
        }
      ],
    "emails":
      [
        {
          "type": "other",
          "value":"[email protected]
        }
      ],
    "custom_fields":
      {
          "field_a":"12345"
      }
    }'

This code always returns the error 'invalid JSON'

#!/bin/sh

first=John
last=Doe
phone=5555555555
phone_type=other
[email protected]
email_type=other
id=12345

curl https://yoursite.desk.com/api/v2/customers \
-u username:password \
-X POST \
-H "Accept: application/json" \
-H "Content-Type: application/json" \
-d '{
    "first_name":'"$first"',
    "last_name":'"$last"',
    "phone_numbers":
      [
        {
          "type":'"$phone_type"',
          "value":'"$phone"'
        }
      ],
    "emails":
      [
        {
          "type":'"$email_type"',
          "value":'"$email"'
        }
      ],
    "custom_fields":
      {
          "field_a":'"$id"'
      }
    }'

For what it's worth, as I have been tweaking the code occasionally the error code will display "emails": "value": (invalid) and "phone_numbers":"value":(invalid)

In your example "$first" is expanded to John (the double quotes are lost). The same goes for the other expansions. Include the required double quotes in the single quoted part of your command (but preserve the double quotes around the variable expansions):

#!/bin/sh

first=John
last=Doe
phone=5555555555
phone_type=other
[email protected]
email_type=other
id=12345

curl https://yoursite.desk.com/api/v2/customers \
-u username:password \
-X POST \
-H "Accept: application/json" \
-H "Content-Type: application/json" \
-d '{
    "first_name":"'"$first"'",
    "last_name":"'"$last"'",
    "phone_numbers":
      [
        {
          "type":"'"$phone_type"'",
          "value":"'"$phone"'"
        }
      ],
    "emails":
      [
        {
          "type":"'"$email_type"'",
          "value":"'"$email"'"
        }
      ],
    "custom_fields":
      {
          "field_a":"'"$id"'"
      }
    }'
