Step 1 — Create an API key
1
Open API keys
In Mailchimp, go to Account & billing → Extras → API keys.
2
Create a key
Click Create A Key and copy it. The key ends with your datacenter, e.g.
-us21.Step 2 — Connect in Ryze
In Workspace Settings → Integrations, click Connect on the Mailchimp card, paste the key into API key, and click Continue. Ryze reads the datacenter from the key suffix and shows your account name on the card.Troubleshooting
- Key rejected — copy the full key including the
-usXXsuffix; without it Ryze can’t route to your datacenter. - Wrong account — each key belongs to one Mailchimp account. Create the key while logged in to the account you want.
