Generic Webhook

The webhook provider can be useful for triggering more complex flows or prompt chains end to end in your app.

It is specified like so:

providers:
  - webhook:http://example.com/webhook

promptfoo will send an HTTP POST request with the following JSON payload:

{
  "prompt": "..."
}

It expects a JSON response in this format:

{
  "output": "..."
}

Passing custom properties

It is possible to set webhook provider properties under the config key by using a more verbose format:

providers:
  - id: webhook:http://example.com/webhook
    config:
      foo: bar
      test: 123

These config properties will be passed through in the JSON request payload:

{
  "prompt": "...",
  "config": {
    "foo": "bar",
    "test": 123
  }
}
