Testing Webhooks
By testing webhooks, you can verify the configuration process as well as inspect and parse
the event messages you will receive from Mist. If you do not have a webhook receiver available
to you, you can use a public, free service. Many such services enable you to receive and
inspect the incoming webhook POST messages from Juniper Mist. These public
sites create a random URL that you can use on a temporary basis. The data that you received is
ephemeral and is deleted as soon as you close your browser. Using one of these sites from your
browser, you can identify parameter data from the message payloads to help create your
workflow.
After you configure your webhook, you can trigger it and view those messages as they are received on the public webhook receiver.
Two of these free testing webhook receivers are:
These sites are not Juniper maintained and are to be used at your own risk.
This is an excellent time to test end-to-end connectivity from your respective Mist cloud instance to your defined webhook receiver. This validates that no devices (a firewall or router) are blocking communications between the two endpoints.
This can be done from the API by issuing a POST (from your REST client) to, in this case,
your site, the configured webhook (id) as seen in this example:
POST
/api/v1/sites/4ac1dcf4-9d8b-7211-xxxxxx-xxxxxxxxxxxx/webhooks/18ff1f91-a9e0-c3b7-xxxx-xxxxxxxxxxx/ping A successful result looks like this:
{
"topic": "ping",
"events": [
{
"site_id": "4ac1dcf4-9d8b-7211-xxxxxx-xxxxxxxxxxxx",
"id": "18ff1f91-a9e0-c3b7-xxxx-xxxxxxxxxxx",
"name": "my webhook",
"timestamp": 1461220784
}
]
