Unable to use the Add Many Records Method

Hi,
Attempting to use the “Add Many Records” methods returns a 415 error

For example, sent this json:
[
{
“id”:“3”,
“First”:“Chris”,
“Last”:“Hall”,
“Number”:“8885551234”
},
{
“id”:“4”,
“First”:“Chris”,
“Last”:“Hall”,
“Number”:“8885551234”
}
]

Hello Amybritton
The add many records did not work because you have a RAW body type of Javascript instead of JSON. We will only accept the JSON payload format for this POST. Please update and test again and let us know if you continue to experience any problems.
