Example Headers And Payloads

To work with a webhook, you need to know a bit about the payload you’ll be receiving. Each event you receive a payload for will contain special headers that describe what the event is.

Example Headers

X-Request-Id: d535c62b-063e-4ace-90ce-f7b579d6c37c
Content-Type: application/json; charset=UTF-8
User-Agent: Nexus/3.1.0-SNAPSHOT (PRO; Mac OS X; 10.11.1; x86_64; 1.8.0_60)
X-Nexus-Webhook-Signature: 687f3719b87232cf1c11b3ef7ea10c49218b6df1
X-Nexus-Webhook-Id: rm:repository:asset
X-Nexus-Webhook-Delivery: 7f4a6dde-5c68-4999-bcc0-a62f3fb8ae48

Of special importance are the following three headers:

Header	Description
`X-Webhook-Signature`	This is the HMAC digest of the body of the payload, if an optional secret key has been configured
`X-Nexus-Webhook-Delivery`	This is a unique UUID identifying the event
`X-Nexus-Webhook-Id`	This is the event type, e.g. `rm:repository:asset`

A payload will be returned with each event type, an example of one for a repository asset webhook is shown below:

Example Payload

{
   "timestamp" : "2016-11-10T23:57:49.664+0000",
   "nodeId" : "52905B51-085CCABB-CEBBEAAD-16795588-FC927D93",
   "initiator" : "admin/127.0.0.1",
   "repositoryName" : "npm-proxy",
   "action" : "CREATED",
   "asset" : {
   "id" : "31c950c8eeeab78336308177ae9c441c",
   "assetId" : "bnBtLXByb3h5OjMxYzk1MGM4ZWVlYWI3ODMzNjMwODE3N2FlOWM0NDFj",
   "format" : "npm",
   "name" : "concrete"
  }
}

Events share common fields, described in detail below:

Header	Description
`nodeId`	A UUID that identifies which Nexus Repository Manager node the event originated from
`timestamp`	The ISO 8601 representation of the time the event occurred
`initiator`	The userId or "anonymous" for system events

Below, you will find examples of many Payloads that are returned, to help you get up and running with webhooks in Nexus Repository Manager.
