API v1 contact_sync returns "Invalid Request"

const apiKey = 'xxxxxx';
const apiURL = 'https://myaccount.api-us1.com/admin/api.php?api_key=' + apiKey + '&api_action=contact_sync' + '&api_output=json';

var emailAddress = 'zapier-test@gmail.com'; //inputData.emailAddress;
var FirstName = 'FFFFF'; //inputData.FirstName;
var LastName = 'LLLLL'; //inputData.LastName;

const postData = {
  email: emailAddress, // Replace with the email of the contact you want to sync
  first_name: FirstName, // Replace with the first name of the contact
  last_name: LastName,
  form: 22
};

fetch(apiURL, {
  method: 'POST',
  headers: {
    'Content-Type': 'application/x-www-form-urlencoded',
  },
  body: new URLSearchParams(postData),
})
.then(response => response.text()) // Read the response as text
.then(text => {
  console.log('Response Text:', text); // Log the response text for debugging
  try {
    const data = JSON.parse(text); // Parse the response text as JSON
    callback(null, data);
  } catch (error) {
    callback(error, null); // Handle JSON parsing error
  }
})
.catch(error => {
  callback(error, null);
});

Any help troubleshooting is appreciated.

ChatGPT is my friend for this stuff

const url = 'https://xxx.api-us1.com/admin/api.php';
const apiKey = 'xxxxx';

const params = {
    api_action: 'contact_sync',
    api_output: 'json', 
};

const postData = {
    email: 'test@example.com',
    first_name: 'FirstName',
    last_name: 'LastName',
    form: 22,
 };

// Construct the query string from params
const queryString = new URLSearchParams(params).toString();

// Construct the body data from postData
const bodyData = new URLSearchParams(postData).toString();

// Construct the full URL with query string
const fullUrl = `${url}?${queryString}`;

const options = {
    method: 'POST',
    headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
        'API-TOKEN': apiKey
    },
    body: bodyData
};

fetch(fullUrl, options)
    .then(response => response.json()) // Changed to response.json() to directly handle JSON response
    .then(data => {
        // Use callback to return data
        callback(null, data);
    })
    .catch(error => {
        console.error('Error:', error);
        callback(error, null);
    });

@RobertSegelquist - this works brilliantly! I tested it, and it created a new contact in AC, subscribed to the correct list, set the status as Unconfirmed AND sent the opt-in email!

Where there’s a will, there’s a way! Thank you!

Aside: I too was using ChatGPT but wasn’t quiet able to get G to generate that flawless code - what prompt(s) did you feed to get that result?

The complete solution, ready for Zapier:

/*
This script is written for a Code by Zapier action using ActiveCampaign's API version 1 and contact_sync api action.

With a properly configured form in AC that implements double opt-in, the script will create a new contact in AC, subscribe the contact
to the correct list, set the contact's status as Unconfirmed, and send an opt-in email.

Created 2024-05-06 by West Wind Web Works and Zephyr Mays with a MASSIVE assist from Robert Segelquist, ActiveCampaign Superuser.

const url = 'https://myaccount.api-us1.com/admin/api.php';
const apiKey = 'abc123...';


//Values from previous Zapier action, e.g. external lead generator that does not natively integrate with AC.
var emailAddress = inputData.emailAddress; 
var FirstName = inputData.FirstName;
var LastName = inputData.LastName;

const params = {
    api_action: 'contact_sync',
    api_output: 'json', 
};

const postData = {
    email: emailAddress,
    first_name: FirstName,
    last_name: LastName,
    form: 123, // this value is the form # found at https://myaccount.activehosted.com/app/forms/123
 };

// Construct the query string from params
const queryString = new URLSearchParams(params).toString();

// Construct the body data from postData
const bodyData = new URLSearchParams(postData).toString();

// Construct the full URL with query string
const fullUrl = `${url}?${queryString}`;

const options = {
    method: 'POST',
    headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
        'API-TOKEN': apiKey
    },
    body: bodyData
};

fetch(fullUrl, options)
    .then(response => response.json()) // Changed to response.json() to directly handle JSON response
    .then(data => {
        // Use callback to return data

    })
    .catch(error => {
        console.error('Error:', error);
        callback(error, null);
});

@RobertSegelquist — again, thanks for bringing this solution to life!

I’ve just tinkered enough to figure out the back and forth.

Gist of it is saying, “made that update, now this error…”
