Webhooks

Overview

Webhooks mechanism allows platform integrations by subscribing to certain Events. When the Event is triggered, the platform sends an HTTP POST request with the payload to the configured webhook URL.

Subscription

Subscription to the events is configured during instance handshake.

To change existing subscriptions, the handshake can be repeated with a different response body.

Webhook receiver

Here are some requirements and tips for webhook receiver endpoints:

• An endpoint must respond with HTTP 200 (OK). Otherwise, webhook delivery is retried.

• Webhook endpoint should respond as quickly as possible. If response time exceeds the predefined duration (5 seconds currently), delivery is considered as failed and retried. If heavy processing is possible within the endpoint routine, it is worth extracting it into background processing (queue).

Error handling and retries

Webhook delivery is considered as failed in such cases:

• network error

• response code is not 200 OK

• it took too long for the receiver to respond (timeout)

In case of failure, delivery is retried. Currently, there are 5 attempts in total to deliver the webhook, with 3 seconds interval between each.

Each event payload has an ID parameter that uniquely identifies the triggered webhook event. It is the same for every delivery retry, so it can be used to guarantee that a specific event is processed once at most.

Webhook body schema

Event payload of any type has the following schema:

Property	Format	Description
id	string (UUID)	Unique identifier of the triggered webhook event
ts	number	Timestamp of emitted event, in milliseconds
type	string	Webhook event type; Possible options are described below
payload	object	An object containing event type-specific payload
