Overview

This node operation adds one or more contacts to a specified list in the Warmr Lists system. It is useful for managing list memberships by associating contacts with particular lists, such as adding subscribers to a mailing list or members to a group. For example, you can add multiple contact UUIDs to a marketing list to target them with specific campaigns.

Use Case Examples

1. Add multiple contacts to a customer engagement list by providing the list UUID and a comma-separated string of contact UUIDs.
2. Use this operation to update membership of a list dynamically based on user actions or external triggers.

Properties

Output

JSON

• json - The response from the Warmr Lists API after adding contacts, typically including details of the updated list or confirmation of the addition.

Dependencies

• Requires an API key credential for the Warmr API to authenticate requests.

Troubleshooting

• Ensure the List UUID and Contact UUIDs are valid and exist in the Warmr system; invalid UUIDs will cause errors.
• The contact UUIDs must be provided as a comma-separated string without extra spaces or invalid characters.
• API key credential must be correctly configured and have permissions to modify list memberships.
• Common error messages include authorization failures (check API key), invalid UUID format, or network issues. Verify credentials and input formats to resolve these.
