Webhook Reply Node
The Webhook Reply Node allows a workflow to send a reply back to a webhook trigger (as long as the webhook is configured to wait for a reply).
All the standard components of an HTTP response are configurable in the Webhook Reply Node - the response code, the body, and the headers.
In the above example, the response code is set to
200, although that field is templatable and so can be configured from the current payload. It is expected to resolve to a valid response code number, and if it does not, the reply will default to a response code of
The body of the reply can be set either as a string template or as a payload path. In the above example, it is a string template that resolves to a string of JSON. If payload path is chosen and the payload path points to an object, that object is stringified as JSON for use as the body. The body is allowed to be empty, if no body is desired on the reply.
Arbitrary headers can also be set on the reply. Both the header name and value fields are templatable, so they are configurable based on the payload. In the example above, only one header field is set -
Content-Type is set to
application\json. This is set because the body of the reply is JSON. This will probably be the most common header to set - Losant does not try an automatically determine the content type of the body of the reply.
Notes About Security
- Webhook replies allow a limited set of values for the
text/csv. If no
Content-Typeis set, or an invalid
Content-Typeis set, the
Content-Typeof the response will be set to
- Losant automatically sets protective values for the following headers, none of which can be overridden in a webhook reply:
The Webhook Reply Node has one optional advanced option - setting the payload path to the
The reply ID path by default is
data.replyId - which is where a webhook (that expects a reply) places the reply ID for the current webhook trigger request. But if for some reason you have moved the replyId to a different part of the payload, or you are using multiple workflows and passing the replyId between them under a different field name, you can set the path to that field here. If there is no reply ID at the path given, the Webhook Reply Node does nothing.
