Instance → List
AI-generatedSummary
Lists every WhatsApp instance on the Wasup deployment by calling GET /api/instances with the configured Wasup API credentials.
Inputs
None.
Output shape
The parsed JSON response from /api/instances, emitted as n8n items (returnJsonArray). Each input item produces output linked to it. The instance list appears under an instances key. The source reads fields such as id, name, status and connectedPhone from each entry.
The exact response shape is determined by the Wasup server. If the response is an object containing an
instancesarray, it is emitted as one item with that array, not split into one item per instance. If the node runs once per input item, the same full list is returned for each item. With Continue On Fail enabled, errors are returned as an item with anerrormessage.
Examples
Example 1: Get all instances and their connection status on a schedule to alert on disconnected numbers
Resource: Instance, Operation: List. No other parameters. Follow with a Split Out node on instances and an IF node that checks status.
Example 2: Look up an instance ID before sending a message
Resource: Instance, Operation: List. Then use the returned id in later Wasup nodes via the 'By ID' mode.
