Configuration
7 fields, none required. A dotted path is a nested object and name[] an array of objects — the editor renders the same tree.
| Field | Type | Required | Default | Constraints | Example |
|---|---|---|---|---|---|
place A place name to resolve through the Geocoding API, as 'city', 'city,country code' or 'city,state code,country code' for the US — for example 'London,GB'. | string | No | — | — | London,GB |
lat Latitude of the place to look up, from -90 to 90. Give it together with 'lon', or name a 'place' or a 'postcode' instead. | number | No | — | -90–90 | 51.5074 |
lon Longitude of the place to look up, from -180 to 180. Give it together with 'lat', or name a 'place' or a 'postcode' instead. | number | Conditional | — | -180–180; only with lat | -0.1278 |
postcode A post code and its two-letter country code, divided by a comma, resolved through the Geocoding API — for example '94040,US'. | string | No | — | — | 94040,US |
units The unit system for this call: 'standard' is Kelvin and metres per second, 'metric' is Celsius, 'imperial' is Fahrenheit. Defaults to the connection's setting. | string | No | — | one of "standard", "metric", "imperial" | — |
lang Two-letter language code for the human-readable weather descriptions, such as 'es' or 'de'. Defaults to the connection's setting, and to English. | string | No | — | — | en |
exclude Comma-separated parts of the answer to leave out, any of: current, minutely, hourly, daily, alerts. | string | No | — | — | minutely,alerts |
- At least one of place, lat, postcode must be set.

}Notes
- One Call API 3.0 needs the separate 'One Call by Call' subscription on the OpenWeather account; without it OpenWeather answers 401 for this endpoint.
- A 'place' or 'postcode' costs one extra Geocoding API call before the weather call; passing 'lat' and 'lon' skips it.
- 'minutely' is only published for some places and 'alerts' only when an agency has issued one, so both are absent more often than not.
See One Call Forecast run in a workflow.
In a technical demo we add the OpenWeather connection, drop the node on the canvas and let Workflow Health pre-flight it before the first real run.
