ℹ️ About webhooks
Webhooks enable Ondato to send real-time notifications about changes in your resources. These notifications are sent as POST requests to your server immediately after the event occurs, and the request body includes information about the resource.
🔐 Security
Ondato uses HTTPS to transmit these notifications in the form of a JSON payload.
🛒 Ordering
Ondato delivers events asynchronously. Therefore, you might receive them out of order and need to handle them accordingly.
📫 Webhook IP addresses
All webhook requests will originate from the following IP addresses:
Code Block |
---|
20.31.10.47 20.31.227.231 20.76.229.117 20.76.229.248 213.226.187.101 |
Please ensure that you whitelist the above IPs to receive webhook notifications.
🔃 Retry logic
Upon sending a webhook notification, we are waiting for a success response for 30 seconds. Otherwise, if your endpoint does not respond, the webhook is queued for retry.
We use an exponential backoff retry policy for event delivery. The attempt to resend the notifications is according to the following schedule on a best effort basis:
Panel | ||||||||
---|---|---|---|---|---|---|---|---|
| ||||||||
|
If the endpoint responds within 3 minutes, we will make an attempt to remove the event from the retry queue on a best-effort basis. However, duplicates may still be received.
A small degree of randomization is incorporated into all retry steps and may selectively skip certain retries if an endpoint is offline for an extended period or seems to be overloaded.
The maximum number of retry attempts is 30.
When Event Grid is unable to deliver an event within a specific time period frame or after attempting to deliver the event a certain number of times, the event is dropped.
❔ How to start receiving webhooks?
To begin receiving event notifications in your application, you need to follow these steps:
Identify the events you want to monitor.
📄 Please see a full list of events in this section here: https://ondato.atlassian.net/wiki/spaces/PUB/pages/2296184995/Webhooks#%F0%9F%AA%84-Webhook-types.Create a webhook endpoint as an
HTTP
endpoint on your local server.Handle requests from Ondato.
Deploy your webhook endpoint to make it publicly accessible via an
HTTPS
URL.Contact the Ondato support team to register the publicly accessible
HTTPS
URL and provide a list of events you would like to monitor.
Please note that we also support multiple URLs for sending webhooks.
😶🌫️ Requirements for webhook endpoint
Ondato needs to know where to send information about events. To receive webhooks, you must create a webhook endpoint and provide us with the a publicly accessible HTTPS
URL that meets the following criteria:
URL format: https://<your-website-name>/<your-webhook-endpoint>
URL must support
HTTP method.Status colour Green title POST URL must be secure (HTTPS protocol).
URL must support one of the available authentication flows:
basic
| username, passwordoAuth2
| clientID, clientSecret, tokenUrlHMAC
| client-side verification
Handling webhooks events with HMAC Authentication
Info |
---|
To start receiving webhooks events with HMAC authentication you should first receive your secret from Ondato. |
HMAC webhook verification steps:
1. In web request you would receive the Ondato-Signature header
Request header example: Ondato-Signature: t=1712825621, s=7026783cfd8b88a2652f23e789f1ec7de02b7c6ef8362892fe743fead4bab71d
2. Parse value t
from the header (for given example 1712825621
) - timestamp
3. Get received body/json string - json
4. Join to a single string $"{timestamp}.{json}"
(joining to single string may vary on your programming environment) - message
5. Using secret compute HMACSHA256 hash (lower case) for message - computedHash
6. Parse value s
from the header (for a given example 7026783cfd8b88a2652f23e789f1ec7de02b7c6ef8362892fe743fead4bab71d
) - signature
7. Compare computedHash with signature - those should match
