GOWA

Overview

This node integrates with the Go WhatsApp Web MultiDevice API to manage WhatsApp groups programmatically. Specifically, the "Create Group" operation under the "Group" resource allows users to create a new WhatsApp group by specifying its name and optionally adding participants via their phone numbers.

Common scenarios for this node include automating group creation for customer support teams, marketing campaigns, or community management where multiple contacts need to be grouped dynamically without manual intervention.

For example, a user can input a group name like "VIP Customers" and provide a list of phone numbers to instantly create a WhatsApp group including those participants.

Properties

Output

The node outputs JSON data representing the result of the group creation operation. This typically includes details about the newly created group such as its unique identifier, name, and participant information.

If the operation fails, the output JSON will contain an error message describing the issue.

The node does not output binary data.

Dependencies

• Requires an active connection to the Go WhatsApp Web MultiDevice API.
• Needs an API authentication token or key configured in the node credentials.
• The base URL for the API must be set in the node's credential configuration.

Troubleshooting

• Common issues:

  • Invalid or missing API credentials will cause authentication failures.
  • Incorrectly formatted phone numbers in the participants list may lead to errors or participants not being added.
  • Network connectivity problems can prevent communication with the API.

• Error messages:

  • "Unknown resource": Indicates that the specified resource is not recognized; ensure "Group" is selected.
  • Errors returned from the API will be included in the output JSON under an error field if "Continue On Fail" is enabled.

• Resolutions:

  • Verify API credentials and host URL are correctly configured.
  • Ensure phone numbers are in the correct format (e.g., country code followed by number, no spaces).
  • Check network access and firewall settings.
