MailChimp v3.0 Events | Cloud Elements Help Center

Cloud Elements supports events via polling or webhooks depending on the API provider. For more information about our Events framework, see Events Overview.

Supported Events and Resources

Cloud Elements supports webhook events for MailChimp. After receiving an event, Cloud Elements standardizes the payload and sends an event to the configured callback URL of your authenticated element instance. For more information about webhooks at MailChimp including the currently available webhooks, see their webhooks documentation.

Configure Webhooks Through the UI

To configure webhooks through the UI, follow the same steps to authenticate an element instance, and then turn on events. For more information, see Authenticate an Element Instance with Events (UI) or the element-specific authentication topic.

Configure Webhooks Through API

Use the /instances endpoint to authenticate with MailChimp and create an element instance with webhooks enabled.

Note: The endpoint returns an element instance token and id upon successful completion. Retain the token and id for all subsequent requests involving this element instance.

To authenticate an element instance with webhooks:

Get an authorization grant code by completing the steps in Getting a redirect URL and Authenticating users and receiving the authorization grant code.

Construct a JSON body as shown below (see Parameters):

{
  "element": {
    "key": "mailchimpv3"
  },
  "providerData": {
    "code": "<AUTHORIZATION_GRANT_CODE>"
  },
  "configuration": {
    "oauth.api.key": "<MailChimp v3.0 app Key Name>",
    "oauth.api.secret": "<MailChimp v3.0 app Secret Name>",
    "oauth.callback.url": "<MailChimp v3.0 app Callback URL Name >",
    "event.notification.enabled": true,
    "event.notification.callback.url": "<CALLBACK_URL>"
  },
  "tags": [
    "<Add_Your_Tag>"
  ],
  "name": "<INSTANCE_NAME>"
}

Call the following, including the JSON body you constructed in the previous step:
```
POST /instances
```
Note: Make sure that you include the User and Organization keys in the header. For more information, see Authorization Headers, Organization Secret, and User Secret.
Locate the token and id in the response and save them for all future requests using the element instance.
