# write-http

For each event, evaluate a JavaScript `request` function and make the resulting HTTP call.

The request body is:

1. `event.payload` (string) when present, or
2. the full event serialised as JSON otherwise

## Config

**Required:**
- `request`: A JavaScript arrow function (or function expression) as a string. Receives the event object, must return `{ url, method?, headers? }`.
  - `url` *(required)*: Target HTTP endpoint
  - `method`: HTTP method — default `POST`
  - `headers`: Object of additional HTTP headers

## Example

```yaml
pipeline:
  write-http:
    module: write-http
    inputs: [format-json]
    config:
      request: "event => ({ method: 'PUT', url: 'http://localhost:1337/user/' + event.id, headers: { 'user-agent': 'my-agent/1.0' } })"
```
