I'm trying to create an entry in a Gravity form via API post in Google Apps script.

An entry gets created but the values are showing blank. any insight of where I'm possibly going wrong would be appreciated.

Below is my code:

function gravityForms(){

const url = 'https://example.com/wp-json/gf/v2/forms/18/entries';

const payload = [{"2":"My name"}];

const options = {
    "method" : "post",
    "payload" : JSON.stringify(payload),
    "muteHttpExceptions" : true
  };
  
    options.headers = {    
    "Content-Type" : "application/json",
    "Authorization" : "Basic " + Utilities.base64Encode("ck_xxxxxxxxxxxx:cs_xxxxxxxxxxxxxxxxxx")
  };

const res = UrlFetchApp.fetch(url, options);

console.log(res.getContentText());

}

This is the response I get back in the logger

{"0":{"2":"My name"},"form_id":18,"id":3320}
