Webhooks API

Aurinko's Webhooks API enables real-time event notifications for email, calendar, contacts, and task updates by subscribing to specific resources and handling webhook payloads efficiently.

Aurinko Webhooks API

Webhooks allow your apps to receive real-time updates from the Aurinko platform. By registering a webhook URL, you can get notified when specific events happen.

Aurinko account setup

---

First, create your account in the Aurinko portal, then follow the guide to Get Your Developer API Keys.

Setting up a Webhook

---

1. Prepare an endpoint URL on your server.

2. Provide this endpoint to our system through the event subscription process.

3. Ensure your endpoint can handle POST requests and supports the initial url verification step.

4. To leverage native Gmail push notifications Configure Cloud Pub/Sub.

Authentication

---

Webhooks are secured using a shared secret that is used to generate a signature. The signature is sent in the HTTP header of each request, allowing you to verify the authenticity (see Notification Validation). The signing secret can be found on your app's dashboard page:

API Resources

---

The Aurinko webhook events are associated with API resources (parts of the API) and subscriptions are created for those resources. Here is the list of available API resources:

• /email/messages - events representing mailbox changes

• /email/tracking - events representing email tracking changes

• /calendars/primary/events, /calendars/{calId}/events - events representing calendar changes

• /contacts - events representing address book changes

• /tasklists/default/tasks, /tasklists/{tlId}/tasks - events representing todo item changes

Subscribing

---

To create a new subscription POST a resource and a notification url to the subscriptions endpoint:

curl -H 'Authorization: Bearer <access token>' \
    -X POST https://api.aurinko.io/v1/subscriptions \
    -d '{
        "resource": "/email/messages",
        "notificationUrl": "https://myserver/pushEvents"
}'  

Response:

{
    "id": "87665448354",
    "resource": "/email/messages", 
    "notificationUrl": "https://myserver/pushEvents" 
}  

Payloads

---

Each API resource may have its own payload format. Below is a sample payload that is common for email/messages, /contacts, /calendars/{id}/events, /tasklists/{id}/tasks:

{
    "subscription" : 1217,
    "resource" : "/email/messages",
    "accountId" : 1532,
    "payloads" : [
        {
            "id" : "AQMkAGY0ZTQyM2ZlLTM5N2UtNGZkYy1hZmQ2LTJkNDdmNTlmMGZlNgBGAAADhXGu-
                   WVhvEKOWPBUZKnvPwcAAAAUsezTfrRCmmimIKi3ETUAAAIBCQAAARSx7NN\_tEKaaKY
                   gqLcRNQAGD3-O7wAAAA==",
            "changeType" : "updated"
        },
        {
            "id" : "AQMkAGY0ZTQyM2ZlLTM5N2UtNGZkYy1hZmQ2LTJkNDdmNTlmMGZlNgBGAAADhXGu-
                   WVhvEKOWPBUZKnvPwcAAAAUsezTfrRCmmimIKi3ETUAAAIBDAAAARSx7NN\_tEKaaKY
                   gqLcRNQAGD3-S2QAAAA==",
            "changeType" : "created"
        }
    ]
}

Next, an example of the email/tracking events (eventType can be open, reply, or bounce):

{
    "subscription": 1271,
    "resource": "/email/tracking",
    "accountId": 1626,
    "payloads": [
        {
            "id": 1670,
            "createdAt": "2023-09-29T09:13:44Z",
            "eventType": "reply",
            "threadId": "",
            "messageId": "",
            "internetMessageId": "<[email protected]>",
            "trackingId": 1614,
            "context" : "",
            "trackingCode": "5c59753a-3e4f-4c2c-a2f7-1e5c4fc538d2"
        },
        {
            "id": 1687,
            "createdAt": "2023-09-29T10:59:20.236665Z",
            "eventType": "open",
            "location" : "",
            "userAgent": "Mozilla/4.0 (compatible; ms-office; MSOffice 16)",
            "remoteAddr": "176.116.84.4",
            "trackingId": 1617,
            "context" : "",
            "trackingCode": "fce4d887-1aea-4b2f-93fc-5e02147f9c3d"
        }
    ]
}

{
    "subscription" : 3223,
    "resource" : "/email/tracking",
    "accountId" : 1464,
    "payloads" : [
        {
            "id" : 5973,
            "createdAt" : "2024-10-23T17:15:57Z",
            "eventType" : "replyBounce",
            "threadId" : "",
            "messageId" : "",
            "internetMessageId" : "<[email protected]>",
            "trackingId" : 3230,
            "context" : "",
            "trackingCode" : "bce0e37e-9f90-4171-9f76-926c77b2c9b1"
        }
    ]
}

When an email is first processed for tracking, an ‘Initial’ event is triggered. This event occurs only once when tracking begins, typically upon sending the email, and is not included in subsequent tracking updates:

{ 
    "subscription" : 3190, 
    "resource" : "/email/tracking", 
    "accountId" : 1535, 
    "payloads" : [ 
        { 
            "id" : 5822, 
            "createdAt" : "2024-10-17T13:35:04Z", 
            "eventType" : "initial", 
            "threadId" : "", 
            "messageId" : "", 
            "internetMessageId" : "<[email protected]>", 
            "trackingId" : 3159, 
            "context" : "", 
            "trackingCode" : "e2d9e1fb-e1b2-4a57-96d9-5bc0fe10b129" 
        } 
    ] 
}

Handling Webhooks

---

When you receive a webhook:

1. Validate the signature to ensure it's from the Aurinko platform.

2. Respond with a 200 OK as quickly as possible.

3. Process the event data asynchronously.

Retries

---

If your endpoint responds with any HTTP status other than 200 OK or 422 Unprocessable, Aurinko will attempt to resend the webhook 1, 2, 4, 8 ... etc seconds (the interval won't increase beyond 10mins). Responding with the 422 HTTP status results in removing the subscription.

Lifecycle events

---

If for some reason your webhook subscription becomes problematic (i.e. because account credentials have expired), Aurinko will send a lifecycle event like this:

{
    "subscription" : 1217,
    "resource" : "/email/messages",
    "accountId" : 1532,
    "lifecycleEvent": "error",
    "error": "Error message"
}

When the subscription comes back to life, Aurinko will send:

{
    "subscription" : 1217,
    "resource" : "/email/messages",
    "accountId" : 1532,
    "lifecycleEvent": "active"
}

Deleting a webhook

---

curl -H 'Authorization: Bearer <access token>' \
    -X DELETE https:/api.aurinko.io/v1/subscriptions/{id}
