AI-generatedSummary
Creates a new empty Wasup WhatsApp instance (not yet linked to a phone number) by POSTing to /api/instances, and returns the API's response for the created instance.
Inputs
- Additional Fields > Custom Instance ID — Custom instance ID sent as
id. The API auto-generates one if omitted. - Additional Fields > Name — Display name for the instance, sent as
name. - Additional Fields > Webhook URL — URL to forward inbound messages to, sent as
webhookUrl.
Output shape
One JSON item per input item, containing the Wasup API's response to the instance creation call (the new instance's details).
Empty-string fields are stripped from the request body, so with no fields set an empty body is sent. The exact response fields aren't defined in the node. With Continue On Fail enabled, errors are returned as an item with an
errormessage.
Examples
Example 1: Provision a blank instance with an auto-generated ID
Resource: Instance, Operation: Create, leave Additional Fields empty.
Example 2: Create a named instance that forwards inbound messages to an n8n webhook
Additional Fields: Name = 'Support Line', Webhook URL = 'https://your-n8n.com/webhook/wasup-inbound'.
Example 3: Create an instance with a predictable ID
Additional Fields: Custom Instance ID = 'support-1', Name = 'Support'.
