Overview
This node operation "Get Join Info" under the "Group" resource allows you to retrieve information about a WhatsApp group from an invite link or code. It is useful when you want to preview details of a group before joining it, such as the group's subject, description, participants count, or other metadata provided by the WhatsApp API via Wappfy.
Common scenarios:
- Validating a group invite link/code before joining.
- Displaying group info in your workflow for decision-making.
- Automating group management tasks that require group metadata.
Practical example:
You have received a WhatsApp group invite link and want to fetch the group's name and participant count before deciding to join. Using this node operation, you input the invite link/code, and the node returns the group's details.
Properties
| Name | Meaning |
|---|---|
| Invite Link/Code | The WhatsApp group invite link or code used to get the group's join information. |
Output
The output is a JSON object containing the group information retrieved from the invite code. This typically includes details such as the group subject (name), description, participant count, and possibly other metadata related to the group.
The exact structure depends on the response from the Wappfy API's /groups/join-info endpoint but generally provides all relevant data needed to understand the group before joining.
No binary data output is involved in this operation.
Dependencies
Requires an active Wappfy API credential with:
- Base URL of the Wappfy API instance.
- Instance name identifier.
- An API key for authentication.
The node makes an HTTP GET request to the endpoint:
{baseUrl}/api/{instanceName}/groups/join-info?code={inviteCode}Ensure the Wappfy API credentials are properly configured in n8n with valid access rights.
Troubleshooting
Common issues:
- Invalid or malformed invite code/link: The API may return an error if the invite code is incorrect or expired.
- Network or authentication errors: If the API key or base URL is misconfigured, requests will fail.
- Rate limiting or API downtime: Temporary failures might occur due to API limits or service unavailability.
Error messages:
"Invalid invite code"or similar indicates the invite code does not correspond to any group.- Authentication errors suggest checking the API key and credentials setup.
- Network errors require verifying connectivity and API endpoint accessibility.
Resolution tips:
- Double-check the invite code format and validity.
- Verify API credentials and permissions.
- Retry after some time if rate-limited or if the API service is temporarily down.
