Authentication

Mailchimp Marketing API key api_key discovered Get key ↗

Authorization: Basic <credential>

Sign in to your Mailchimp account, open the API Keys section, click Create New Key, name it, and copy the generated key immediately. The key grants full account access and is shown only when created; Mailchimp's quick start and fundamentals docs say it is required for direct access to your own account's Marketing API data.

Mailchimp OAuth 2 app (client ID/client secret) oauth2 discovered Set up OAuth ↗

Authorization: Bearer <credential>

To access other users' Mailchimp Marketing data, register an app from the Registered Apps page, click Register An App, complete the form, and save the client_id and client_secret. Then run the OAuth 2 authorization-code flow described in the OAuth guide to obtain a bearer access token. The guide states Mailchimp Marketing access tokens do not expire unless revoked.
