Mailchimp authentication
Prerequisites
Depending on the authentication type you select, you need one of the following credentials:
- OAuth 2.0 Authorization code: the email address and password associated with your Mailchimp account.
- Bring your own OAuth 2.0 app: client ID and client secret.
For creating a private OAuth 2.0 app, follow the steps described in the Mailchimp documentation.
If you encounter any issues while trying to log in, visit the Mailchimp Help section.
Add the Mailchimp connection
To create a connection to your Mailchimp instance, you need to perform the following steps:
- Select Integration Service from the left rail.
- From the Connectors list, select Mailchimp. You can also use the search bar to narrow down the connector.
- Select the Connect to Mailchimp button. You can choose between two authentication types: OAuth 2.0 Authorization code or Bring your own OAuth 2.0 app.
- Enter the required credentials and select Connect.
