Introducing MailChimp’s API
MailChimp provides a robust and approachable API which all account levels have full access to. There is a lot you can do — manage files, manage subscribers, create lists, start campaigns, trigger automation flows, even run all kinds of reports. However, there isn’t a whole lot of information out there on practical applications of the API. Let’s start simple and use the API to create a form which will collect email addresses and add them to a mailing list.
Building The Form
The rest of this guide assumes two things, that you have a MailChimp account and you know how to FTP a PHP file. If you don’t have a MailChimp account, you can sign up for one here. MailChimp is our top recommendation for an email service provider — it works great for one-person teams, small companies and is even a good fit for some large companies. If you don’t know how to FTP a PHP file, you may have a hard time getting this to work so feel free to leave any questions you have in the comments or email me at email@example.com.
Step 1: Create a List
Step 2: Create an API Key
In order to interact with the MailChimp API, you’re going to need to generate an API key. Follow these instructions to create your API key. Make note of this key because you will need it later. Never ever post your API key on the internet or give it to someone you don’t trust. This API key is as powerful as your MailChimp login credentials.
Step 3: Collect More Variables
You need to figure out what datacenter your account is setup for (don’t worry this part is easy). Just look at the url of your browser while you’re logged in. It should begin with https://usX.admin.mailchimp.com. Whatever that usXX field is for you is your datacenter. Mine is us6.
Now you need to determine the ID of your mailing list. The only way I’ve found to do this is by going to the API playground, entering your API key, then clicking on “Lists”. You should see the list that you created in Step 1. Click on the list, and take note of the “id”.
At this point in the game you should be able to fill out the following list with your own values. I have filled it in with mine, so anytime you see one of my values in the code snippets, substitute it for your own.
Step 4: Create the Necessary HTML
Step 5: Create the PHP File
Step 6: Use jQuery to Submit the Form
