Get List ID:

1. Choose a list in which all the subscriber’s information would be stored. In that case, you need to create a list in the Lists page.

Enter into your created list and navigate to Settings » List name and campaign defaults.

Under the List ID label you will find the List ID. Copy List ID for later use in PHP script.

In our example script, a simple newsletter subscription form will be implemented. Once the user submits the subscription form along with the details (First Name, Last Name, and Email), respective details would be added to the list of MailChimp account using MailChimp API and PHP. Also, the subscriber would be able to receive the newsletter of your website via MailChimp.

Subscription Form (index.php)

The index.php file contains the custom subscription form HTML. The subscriber needs to enter their First Name, Last Name, and Email. By clicking on SUBSCRIBE button, the form will submit to the action.php file for adding the subscriber to the MailChimp subscriber list.

Add subscriber to MailChimp List (action.php)

In the action.php file, subscription form data is received and send the subscriber details to the MailChimp using MailChimp API and PHP. To Use MailChimp API, you need to mention API Key and List ID. Insert the API Key and List ID which you’ve got in the previous step.

Here cURL is used to send an HTTP POST request to the List Members endpoint with member information. After adding the subscriber to MailChimp list, the call returns a response. Based on the response ($httpCode) , the status message would be shown to the subscriber.

To add a subscriber, you must include the subscriber’s status in your JSON object. If you include the subscriber’s status subscribed , subscriber email address would be added right away without sending a confirmation email. Use pending status to send a confirmation email to subscriber.
