     1  # Webhook
     2  
     3  Webhook event-source exposes a http server and allows external entities to trigger workloads via
     4  http requests.
     5  
     6  ## Event Structure
     7  
     8  The structure of an event dispatched by the event-source to the sensor looks like following,
     9  
    10          {
    11              "context": {
    12                "type": "type_of_event_source",
    13                "specversion": "cloud_events_version",
    14                "source": "name_of_the_event_source",
    15                "id": "unique_event_id",
    16                "time": "event_time",
    17                "datacontenttype": "type_of_data",
    18                "subject": "name_of_the_configuration_within_event_source"
    19              },
    20              "data": {
    21                "header": {/* the headers from the request received by the event-source from the external entity */},
    22                "body": { /* the payload of the request received by the event-source from the external entity */},
    23              }
    24          }
    25  
    26  ## Specification
    27  
    28  Webhook event-source specification is available [here](https://github.com/argoproj/argo-events/blob/master/api/event-source.md#webhookcontext).
    29  
    30  ## Setup
    31  
    32  1. Install the event source in the `argo-events` namespace.
    33  
    34          kubectl apply -n argo-events -f https://raw.githubusercontent.com/argoproj/argo-events/stable/examples/event-sources/webhook.yaml
    35  
    36  1. The event-source pod is listening for HTTP requests on port `12000` and endpoint `/example`.
    37      It's time to create the sensor.
    38  
    39          kubectl apply -n argo-events -f https://raw.githubusercontent.com/argoproj/argo-events/stable/examples/sensors/webhook.yaml   
    40  
    41  1. Once the sensor pod is in running state, test the setup by sending a POST request to event-source service.
    42
