Request parameters

page
integer optional
Default:
0
Example:
0
size
integer optional
Min: 1
Max: 100
Default:
20
Example:
20
sort
string optional

Multi value sort parameter used for paging across a large data set. The expected format is as follows when specified:

sortField,sortOrder

sortField can be any arbitrary field specific to the content that is being paged sortOrder is ASC or DESC. The sort order defaults to DESC when left unspecified.

A page can be sorted using multiple columns by providing multiple sort query parameters

pageSort=field1,ASC&pageSort=field2,DESC

Default:
updatedAt,DESC
Example:
updatedAt,DESC
applicationId
string optional

Vertex managed application identifier

Example:
c86fcc87-a137-4c37-8d19-17edc7199fef
tenantId
string optional

Vertex customer organizations segment environment id.

Example:
90483dc3-10da-4fc9-9d71-3ec1b37b8a90
tags
string optional

The tags for filtering are provided as a URL-encoded array of tag objects, each containing a key and a value.

For instance, if your tag value is [{“key”:“docNum”, “value”: “3a”}], you’ll need to URL-encode it to %5B%7B%22key%22%3A%22docNum%22%2C%20%22value%22%3A%20%223a%22%7D%5D.

During the filtering process, all tags are combined using an AND operation, meaning a match only occurs if all specified tags are present.

Example:
%5B%7B%22key%22%3A%22docNum%22%2C%20%22value%22%3A%20%223a%22%7D%5D
eventTypeCode

Use this operation to verify your subscription endpoint’s setup. We’ll do this by:

  • Creating a test event (EventType.testPayload) tailored to your subscription.
  • Sending this test event to your subscription.endpoint.url, distinguished by the vertex-webhooks-test=true HTTP header, Subect prefixed [TEST] in emails
  • It’s critical that the application receiving this test notification is designed to log the request, bypass any business logic for the test event, and return a 200 OK response within 500ms.

EventDeliveryResponse

We store each delivery attempt as a separate record. Our system makes a total of five automated delivery attempts. If all five attempts fail, the final record’s status will be PERMANENTLY_FAILED, while the previous four will show a FAILED status.

Here’s how the automated attempts progress:

  • Attempt 1: PENDING → FAILED (at time t1)
  • Attempt 2: RETRYING → FAILED (at t1 + 120 seconds)
  • Attempt 3: RETRYING → FAILED (at t1 + 240 seconds)
  • Attempt 4: RETRYING → FAILED (at t1 + 480 seconds)
  • Attempt 5: RETRYING → FAILED (at t1 + 960 seconds)
  • Additionally, you can initiate a manual delivery attempt via a “replay” operation, which would look like this:

Manual Replay: RETRYING → SUCCEEDED

  • 100 represents OSeries events
  • 1200,1199 represents einvoicing Connectors
  • 100,1199 represents OSeries Connectors

additionalHeaders

You can include additional, arbitrary HTTP headers with your event deliveries. These headers are incredibly flexible and can be used to convey extra context that aids in event processing on the receiving end.

Here are some common ways these custom headers are utilized:

  • Identifying Environments: A custom header could indicate whether an event is for production or test processing, allowing the receiving system to route or handle it accordingly.
  • Providing Partner Details: Headers can carry specific information about the partner system, such as their legal entity, business unit, or other relevant organizational details.

These properties can also be accessed on the notification endpoint using the subscription.additionalHeaders attibute

You can define custom properties during subscripton creation to be included with event deliveries. These properties will appear within the eventDelivery.subscription.additionalProperties field for each delivered event. These properties will be merged as key value pairs in the event payload object.

tags
Array of Tag

The event producer creates tags for each event. It primarily uses the tag keys and their default values as specified in the event type object. However, the producer can also add additional keys not originally defined there. These tags are crucial because subscriptions are matched against them to determine whether an event should be delivered.

Multi value sort parameter used for paging across a large data set. The expected format is as follows when specified:

sortField,sortOrder

sortField can be any arbitrary field specific to the content that is being paged sortOrder is ASC or DESC. The sort order defaults to DESC when left unspecified.

A page can be sorted using multiple columns by providing multiple sort query parameters

pageSort=field1,ASC&pageSort=field2,DESC

tenantId
string optional

Vertex customer organizations segment environment id.

Example:
90483dc3-10da-4fc9-9d71-3ec1b37b8a90
tags
string optional

The tags for filtering are provided as a URL-encoded array of tag objects, each containing a key and a value.

For instance, if your tag value is [{“key”:“docNum”, “value”: “3a”}], you’ll need to URL-encode it to %5B%7B%22key%22%3A%22docNum%22%2C%20%22value%22%3A%20%223a%22%7D%5D.

During the filtering process, all tags are combined using an AND operation, meaning a match only occurs if all specified tags are present.

Example:
%5B%7B%22key%22%3A%22docNum%22%2C%20%22value%22%3A%20%223a%22%7D%5D

This is application defined identifier for event instance, and it will be included in all event delivery attempts.

vertex-webhook-test
string optional

We’ll include this header both when you create a subscription (if testSubscriptionEndpoint is true) and when you perform a subscription test operation.
