How can I test an invocable action if it is not working?

If your invocable action fails to add, remove or resubscribe an audience member, but the flow itself appears to be set up correctly, there is an additional test you can perform. On the Salesforce contact or lead, use our Mailchimp component to manually add the member to an audience via the “Manage Lists” button. This method provides a real-time response from Mailchimp, which will help identify if there is an issue.

It is important to note that you won’t be able to get this level of feedback via the action as it is a bulk process. This is why we recommend testing on a problem record via the component. Visit our support site to learn more about invocable actions and components
