Input Schema

Request message for AgentService.ListChangelogs.

ListChangelogsRequest

JSON representation 
{
  "parent": string,
  "pageSize": integer,
  "pageToken": string,
  "filter": string,
  "orderBy": string
}
Fields
parent

string

Required. The resource name of the app to list changelogs from.
pageSize

integer

Optional. Requested page size. Server may return fewer items than requested. If unspecified, server will pick an appropriate default.
pageToken

string

Optional. The next_page_token value returned from a previous list AgentService.ListChangelogs call.
filter

string

Optional. Filter to be applied when listing the changelogs. See https://google.aip.dev/160 for more details.

The filter string can be used to filter by action, resource_type, resource_name, author, and create_time. The : comparator can be used for case-insensitive partial matching on string fields, while = performs an exact case-sensitive match.

Examples: * action:update (case-insensitive partial match) * action="Create" (case-sensitive exact match) * resource_type:agent * resource_name:my-agent * author:me@example.com * create_time > "2025-01-01T00:00:00Z" * create_time <= "2025-01-01T00:00:00Z" AND resource_type:tool
orderBy

string

Optional. Field to sort by. Only "name" and "create_time" is supported. See https://google.aip.dev/132#ordering for more details.

Fields
fields

map (key: string, value: value (Value format))

Unordered map of dynamically typed values.

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.

FieldsEntry

JSON representation 
{
  "key": string,
  "value": value
}
Fields
key

string
value

value (Value format)

Value

JSON representation 
{

  // Union field kind can be only one of the following:
  "nullValue": null,
  "numberValue": number,
  "stringValue": string,
  "boolValue": boolean,
  "structValue": {
    object
  },
  "listValue": array
  // End of list of possible types for union field kind.
}
Fields
Union field kind. The kind of value. kind can be only one of the following:
nullValue

null

Represents a JSON null.
numberValue

number

Represents a JSON number. Must not be NaN, Infinity or -Infinity, since those are not supported in JSON. This also cannot represent large Int64 values, since JSON format generally does not support them in its number type.
stringValue

string

Represents a JSON string.
boolValue

boolean

Represents a JSON boolean (true or false literal in JSON).
structValue

object (Struct format)

Represents a JSON object.
listValue

array (ListValue format)

Represents a JSON array.

ListValue

JSON representation 
{
  "values": [
    value
  ]
}
Fields
values[]

value (Value format)

Repeated field of dynamically typed values.

Timestamp

JSON representation 
{
  "seconds": string,
  "nanos": integer
}
Fields
seconds

string (int64 format)

Represents seconds of UTC time since Unix epoch 1970-01-01T00:00:00Z. Must be between -62135596800 and 253402300799 inclusive (which corresponds to 0001-01-01T00:00:00Z to 9999-12-31T23:59:59Z).
nanos

integer

Non-negative fractions of a second at nanosecond resolution. This field is the nanosecond portion of the duration, not an alternative to seconds. Negative second values with fractions must still have non-negative nanos values that count forward in time. Must be between 0 and 999,999,999 inclusive.

NullValue

Represents a JSON null.

NullValue is a sentinel, using an enum with only one value to represent the null value for the Value type union.

A field of type NullValue with any value other than 0 is considered invalid. Most ProtoJSON serializers will emit a Value with a null_value set as a JSON null regardless of the integer value, and so will round trip to a 0 value.

Enums
NULL_VALUE Null value.
