Creating a Custom OAuth Application

There are two authentication methods available for connecting to Mailchimp: You can use the APIKey or use OAuth.

OAuth can be used to enable other users to access their own data. It is also useful if you want to:

• control branding of the authentication dialog;
• control the redirect URI that the application redirects the user to after the user authenticates; or
• customize the permissions that you are requesting from the user.

To register a custom OAuth application in Mailchimp and obtain the OAuth client credentials, the OAuthClientId and OAuthClientSecret:

1. Log into your Mailchimp account.
2. Navigate to Account > Extras > API Keys > Register and Manage Your Apps.
3. Enter the information you want to be displayed to users when they are prompted to grant permissions to your application. This information includes your app name, company, and website.
4. If this is a Desktop application, specify a Redirect URI of http://127.0.0.1.
   

   If this is a Web application, specify a Redirect URI where you would like users to be redirected after they grant permissions to your application.

After you have created and registered a custom OAuth app, users can connect to Mailchimp as described in "Connecting to Mailchimp".
