Parameters

Name In Type Description

eventType required

path

string

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

suppressNulls required

query

boolean

If true, omit properties with null values.

Body: WebhookPayloadSchemaDto WebhookPayloadSchemaDto Each item has these fields.

Field Type Description

eventType required

string

The canonical event type string this schema describes. nullable

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

hasRichPayload required

boolean

True when the event delivers a structured `data` object (an aggregate-backed event such as a transaction completion). False for events that deliver only the flat `attributes` map: for those, `dataFields` is empty and the sample shows the flat shape.

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

dataFields required

array of WebhookPayloadSchemaField array of WebhookPayloadSchemaField

The schema of the `data` object's fields, generated from the payload CLR type via the same exclusion logic the runtime projector uses. Empty when `hasRichPayload` is false. nullable

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

Fields of each WebhookPayloadSchemaField:

Field Type Description

name required

string

The JSON field name (the CLR property name, emitted verbatim by the projector). nullable

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

type required

string

The JSON type the value serializes as. One of the values in `WebhookPayloadSchemaTypes`: `string`, `integer`, `number`, `boolean`, `datetime`, `object`, or `array`. nullable

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

nullable required

boolean

Whether the field can be `null` / absent. Reference types and `Nullable` value types are nullable; non-nullable value types are not. This is a best-effort hint derived from the CLR type, not a guarantee that the field is always populated.

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

description required

string

A curated, integrator-facing note about this field, or `null` when its name and type say enough. Sourced from `WebhookPayloadFieldDescriptions` by the field's dotted path, so the catalog and the delivered payload still come from one traversal. nullable

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

fields required

array of WebhookPayloadSchemaField array of WebhookPayloadSchemaField

For `type` == `object`: the nested fields of the object. Null for scalar fields. nullable

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

items required

WebhookPayloadSchemaField WebhookPayloadSchemaField

For `type` == `array`: a descriptor for the array's element. The element descriptor's `name` is empty. Null for non-array fields.

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

truncated required

boolean

True when the describe walk stopped at this node because the recursion-depth ceiling or a type cycle was hit. The actual delivered payload carries a `__truncated` marker in the same place. Defensive guard: not expected on today's tree-shaped aggregates.

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

This body has no documented fields.

sampleEnvelopeJson required

string

A pretty-printed, illustrative sample of the full webhook envelope (id, type, version, createdUtc, scope ids, correlationId, data) with placeholder values. For display only: the values are synthetic, the shape is real. nullable

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

This response has no documented body fields.

default The request failed. The body carries the standard error envelope: a machine-readable `error.code`, a human-readable `error.message`, and `error.validationErrors` when the failure was a validation rejection. The error reference lists the values `error.code` can take. The request failed.

Field Type Description

error required

RemoteServiceErrorInfo RemoteServiceErrorInfo

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

This response has no documented body fields.

429 The request was refused because a rate limit was exceeded, or because something a later retry can clear stopped it. A rate limit refusal carries an `application/problem+json` body: wait at least the interval `Retry-After` names before retrying, then back off. Limits are tuned per deployment, so read the allowance from the response headers rather than assuming a fixed ceiling. Any other refusal carries the standard error envelope as `application/json`, and its `error.code` names the cause.
