Webhooks are a quick way to keep track of event.
Event notifications
Webhooks are used as a messaging channel, to keep line of business systems synchronized with events inside Upodi. A webhook cannot be used as a reliable state of an object or action. The webhook should be used for event notification in conjunction with the API.
What are webhooks
Webhooks refers to a composite event with an object. Webhooks are like a phone call that Upodi rings to notify you of an event. The event could be the creation of a new customer or the payment of a subscription. The webhook endpoint is the system answering that phone call who takes actions based upon the specific information it receives.
Notifications are Event objects. This Event object contains all the relevant information about what just happened, including the type of event and the data associated with that event. The webhook endpoint uses the event details to take any required actions, such as indicating that an order should be fulfilled.
Durability
Webhooks are sent immediate upon the event and action executed. We queue each request and will replay the event until your endpoint returns an HTTP 2xx response (normally 200). If any returns other than 200 is returned, we pause the event for 30 minutes and then replays the event. Upon failure to get a 2xx response code, we then queue the webhook for 4 hours and repeat the call for 48 hours. After this grace period we discard the call, log the event and stop sending this again.
Each call of webhook, is logged to the Activity Log of your Upodi tenant. You can retrieve this log via the API.
How we handle webhooks
Upodi sends webhooks to any public available webserver as HTTP POST. You can specify multiple endpoints in the Upodi application. Each endpoint will recieve a copy of all events.
Upon an event, Upodi will trigger a webhook and try to send this notification to the endpoint(s). In case we do not get a 2xx response from the receiving end, we will reschedule the webhook and keep retrying for up to 3 days.
Summarized:
- Enable a public available web endpoint using HTTP (port 80) or HTTPS (port 443).
- We will keep retrying the webhook endpoint until we receive a 2xx for up to 3 days.
- Upodi catches the response code.
- Method is POST.
- "Signature" will correspond to the authenticity token, and can be used to verify the source.
Webhook body
A webhook holds various information and details. Please make a sample to monitor the response formats.
This is an example of a webhook body (customer, create event):
{
"ID" : "f07b8521-4421-4de6-96a5-178cf498cfef",
"Time" : 131516890300860922, /* filetime timestamp in utc, https://www.epochconverter.com/ldap */
"Signature" : YTYxNWEzMdItZTBgg5i00YWE4LTk5tu6rh2JiZmEyODk5OGMz,
"Action" :"create",
"Issuer" : {
"Url" : "/Customer/create/0ea627de-158e-48b1-bcbb-7fe6058d191c",
"Identifier":"0ea627de-158e-48b1-bcbb-7fe6058d191c"
},
"Data" : null,
"Type" :
"Customer"
}
Need to test a webhook?
Services like Webhook Site enable quick test of the webhook calls from Upodi. Setup a Webhook.site endpoint and add the URL to the Upodi webhook.
