Searching in {{docApp.searchFilterBySpecificBookTitle}}

 {{docApp.currentResultsSearchText}}  in {{docApp.searchFilterBySpecificBookTitle}}
Found {{docApp.searchResponse.totalResultsAvailable}} matches. Showing the top {{docApp.searchResponse.results ? docApp.searchResponse.results.length : 0}}. Use a more specific search to further narrow down the results.
No documentation pages match this search, so all content types are shown. Most matches are in {{docApp.searchDocTypeRescue.best.name}}.
There is no book with the ID "{{docApp.searchBookRescue.bid}}", so the book filter from this link was ignored and results from all books are shown.

You have an odd number of " characters in your search terms - each one needs closing with a matching " character!

Workflows / Trigger Webhook

  • Article
  • 1 minutes to read

Operation Information

Trigger a workflow via its Webhook node URL. The n8n Public API has no execute endpoint, so on-demand runs are started by calling the workflow’s webhook. Provide the full production or test webhook URL. Webhook authentication (if configured on the node) is supplied through the Headers input, not the API key.

This is a Premium Integration.

Authentication

This operation requires no authentication.

Input Parameters

Display Name ID Type Description Required Supported Values
Webhook URL webhookUrl string The full webhook URL of the workflow’s Webhook node, e.g. https://host/webhook/my-path (or /webhook-test/ for the test URL). Yes None provided
Method method string HTTP method to call the webhook with. Must match the method configured on the Webhook node. Defaults to POST. No GET, POST, PUT, PATCH, DELETE
Payload payload array JSON body to send to the webhook. Ignored for GET requests. No None provided
Query Parameters query array Object of query string parameters to append to the webhook URL, e.g. { “ref”: “hornbill” }. No None provided
Headers headers array Object of additional request headers. Use this to satisfy Webhook node authentication (Header Auth) or Basic Auth, e.g. { “Authorization”: “Bearer …” }. No None provided

Output Parameters

Status Code statusCode integer HTTP status code returned by the n8n API.
