In this article, we'll cover what an API is, how to use an API key to grant access to your MailChimp account, and where to go for support with any additional questions that you may have about the MailChimp API.

What Is an API?

API stands for application programming interface. It can be helpful to think of the API as a way for different apps to talk to one another. For many users, the main interaction with the API will be through API keys, which allow other apps to access your account without you giving out your password.

Find or Generate Your API Key

If you want to set up an integration with your MailChimp account, chances are high that you'll need to generate an API key. Users with Manager permissions can generate and view their own API keys. Users with Admin permissions can also see API keys for other account users. Below, you'll learn how to grab an existing API key or generate a new one.

  1. Click your profile name to expand the Account Panel, and choose Account.
  2. Click the Extras drop-down menu and choose API keys.
  3. Copy an existing API key or click the Create A Key button.
  4. Name your key descriptively, so you know what application uses that key.

Disable an API Key

If you're worried that an API key has been compromised, or you no longer use the integration that was accessing your account through a particular API key, you can disable that API key. Follow the steps below to disable the API key.

  1. Click your profile name to expand the Account Panel, and choose Account
    Account Panel
  2. Click the Extras menu and choose API keys
  3. Find the API key you want to disable, and click the Disable link in the Status column for that API key.
    Find the API key you want to disable and click Disable.

API Key Security

API keys grant full access to your MailChimp account and should be protected the same way you would protect your password. In particular, there are a few common scenarios to keep in mind when working with API keys.

  • Give each integration its own API key, and assign labels to each key so you know which key goes with which application. If a specific API key is compromised, you can disable that key without disabling access to all of your other integrations.
  • Be careful not to expose the key to the public (such as in screenshots, videos, or help documentation). Remember that blurring your data isn't always enough. It's best to use "cut" functions in your graphics program to remove the data completely.
  • If a key needs to be shared, generate a new key and label it accordingly so it can be disabled, if needed. Never email the API key, because it would allow access to your MailChimp account if hackers were to compromise your email account.

API Support

Our MailChimp Support Team isn't trained at in-depth API troubleshooting. If you need a developer to help you configure something using the API, check out our great Experts Directory, which lists third-party MailChimp experts who can be hired to help out.

If you're a developer who wants to build your own integration with MailChimp, the first place to check is our API documentation. Any questions not answered by the documentation are best handled by our dedicated API Support Team.

This feature is limited to certain user levels. You can see your user level on the Users & Account Details page and this article explains what each level can access in the account.
