Provide minimum allowed amount of Email Credits in \"Config\" node\n2. Configure Slack OAuth2 connection\n3. Create credentials for Elastic Email:\n 1. Create generic credential type in HTTP Request node\n 2. Select Custom Auth\n 3. In JSON field type:\n```\n{\n\t\"headers\": {\n\t\t\"X-ElasticEmail-ApiKey\": \"<Your EE Auth token>\"\n\t}\n}\n```\n\nTo obtain Elastic Email Auth token refer to official Rest API [docs](https://elasticemail.com/developers/api-documentation/rest-api) or you can get one [here](https://app.elasticemail.com/marketing/settings/new/manage-api) directly\n\n\n\n\n\n\n\n\n\nNeed help?
