How to submit a form (add a subscriber) by mailchimp-api-v3 in Node.js?

Question

I am using mailchimp-api-v3 to submit a form.

This list only has three fields, which are FNAME, EMAIL, and COMPANY.

const Mailchimp = require('mailchimp-api-v3');

const mailchimp = new Mailchimp(myMailchimpAPI);

mailchimp.post(`/lists/${myListId}/members`, {
  FNAME: 'Jack',
  EMAIL: '[email protected]',
  COMPANY: 'Apple'
})
.then(res => console.log(res))
.catch(err => console.log(err));

This gives me error:

[ { field: 'email_address', message: 'This value should not be blank.' } ] }

Answer 1

I figured out after reading the Mailchimp API document. I have to add another two fields email_address and status which are required. Then move the rest of form fields under merge_fields.

The correct code is

const Mailchimp = require('mailchimp-api-v3');

const mailchimp = new Mailchimp(myMailchimpAPI);

mailchimp.post(`/lists/${myListId}/members`, {
  email_address: '[email protected]',
  status: 'subscribed',
  merge_fields: {
    FNAME: 'Jack',
    EMAIL: '[email protected]',
    COMPANY: 'Apple'
  }
})
.then(res => console.log(res))
.catch(err => console.log(err));

It was hard for me to find a simple demo online. Hope this helps for future people.
