Overview

Webhooks in the Veson IMOS Platform are a tool for generating real-time feedback and providing suggested changes to users as they work in the Voyage Estimator. Like Tasks & Alerts, messages are generated and displayed in the notifications panel based on logical rules applied to the current data. Unlike standard Tasks & Alerts, webhooks allow you to write whatever logic you choose in a programming language of your choice, as long as you can host it as a web endpoint. The response payload may also include suggested changes that can be automatically applied to the estimate itself.

...

The expected response is a JSON blob consisting of an array of alert objects. An alert object can have the following fields:

Field	Type	Description
`message`	string	The message that appears to the user. (Required)
`alertType`	One of: `Unspecified`, `PermanentWarning`, `Error`	Determines the icon that appears with the alert. (Optional)
`guid`	string (GUID)	An identifier for the alert. If provided, should be unique in the context of a single response. Can be used to indicate that a given alert is the “same” as one provided in a previous response. (Optional)
`mutation`	object	A mutation that can be applied by the user, in the same format used in the imos/applyUpdateEstimate GraphQL API (Optional)
`displayFields`	object	Customized field labels and values that can be displayed in the body of the card (Optional)
`label`	string	Field label displayed in the body of the card’s Display Fields section (Optional)
`value`	string	Matching value displayed with the label in the body of the card’s Display Fields section (Optional)
`Link`	string	A link specified by the user, presumably leading to the source of the webhook data. (Optional)

Info

If you want “applied” mutations to appear as applied to the end user, include a consistent GUID (globally unique identifier) with the alert object. If no GUID or a new GUID is returned, the mutation will be interpreted as new on the front-end and displayed as such to the end users.

Regardless, reloading an estimate will reload all webhook alerts and their statuses. This is planned for future improvement.
