Overview

This node integrates with the WAMM PRO API to manage WhatsApp contacts and send messages. Specifically, the "Add to Contact List" operation allows users to add a phone number as a contact to a specified contact list within their WAMM instance. This is useful for organizing contacts into lists for targeted messaging campaigns or segmentation.

Practical examples include:

  • Adding new customers to a marketing list after they sign up on a website.
  • Segmenting contacts by interest or region by adding them to different lists.
  • Preparing contact lists before sending broadcast WhatsApp messages.

Properties

Name Meaning
Instance ID Your unique WAMM instance identifier used to target the correct account in the WAMM system.
Phone Number The contact's phone number in international format without the "+" prefix (e.g., 40712345678).
List ID Identifier of the contact list to which the contact will be added.
Contact Parameters Optional JSON string containing additional parameters for the contact (e.g., {"param1":"value1"}).

Output

The node outputs an array of JSON objects, each representing the result of processing an input item. Each object contains:

  • success: Boolean indicating if the operation was successful.
  • apiResponse: The raw response from the WAMM API.
  • operation: The performed operation name ("addToList" in this case).
  • phone: The phone number processed.
  • instanceId: The WAMM instance ID used.
  • timestamp: ISO timestamp when the operation was executed.

No binary data output is produced by this operation.

Dependencies

  • Requires an API key credential for authenticating with the WAMM PRO API.
  • The node makes HTTP GET requests to the WAMM PRO API endpoint at https://app.wamm.pro/api.
  • Proper configuration of the API key credential with token and email is necessary.
  • The user must have a valid WAMM instance ID and contact list IDs configured in their WAMM account.

Troubleshooting

  • Invalid JSON in Contact Parameters: If the Contact Parameters field contains malformed JSON, the node will throw an error indicating invalid JSON format. Ensure the JSON string is correctly formatted.
  • API Authentication Errors: If the API key credential is missing or invalid, requests will fail. Verify that the API token and associated email are correctly set in the credentials.
  • Incorrect Instance ID or List ID: Using wrong or non-existent instance or list IDs will cause the API to return errors or fail silently. Double-check these IDs in your WAMM dashboard.
  • Phone Number Format Issues: The phone number must be in international format without the "+" sign. Incorrect formatting may lead to failed additions.
  • API Response Indicates Failure: The node logs warnings if the API response status is not "success" or "ok". Review the API response message for details.
