ClickStack: Create Source

This endpoint is in beta. API contract is stable, and no breaking changes are expected in the future.

ClickStack: Creates a new source. The request body is a source object without the id field. If an id is sent anyway it is silently ignored (stripped before validation — the request is never rejected because of it). Granularity fields (materializedViews[].minGranularity and metadataMaterializedViews.granularity) accept the same short format the API returns (e.g. 5m, 15s, 1h, 1d).

Beta This endpoint is in beta. API contract is stable, and no breaking changes are expected in the future.

ClickStack: Creates a new source. The request body is a source object without the id field. If an id is sent anyway it is silently ignored (stripped before validation — the request is never rejected because of it). Granularity fields (materializedViews[].minGranularity and metadataMaterializedViews.granularity) accept the same short format the API returns (e.g. 5m, 15s, 1h, 1d).

Permission

The API key must have the control-plane:service:manage-clickstack-api permission.

Authorizations

Authorization

string

header

required

Use key ID and key secret obtained in ClickHouse Cloud console: https://clickhouse.com/docs/cloud/manage/openapi

required

ID of the organization that owns the service.

serviceId

string<uuid>

required

ID of the ClickStack service.

Body

application/json

Option 1
Option 2
Option 3
Option 4
Option 5

name

string

required

Display name for the source.

Example:

"Logs"

kind

enum<string>

required

Source kind discriminator. Must be "log" for log sources.

Available options:

log

Example:

"log"

connection

string

required

ID of the ClickHouse connection used by this source.

Example:

"507f1f77bcf86cd799439012"

from

object

required

defaultTableSelectExpression

string

required

Default columns selected in search results (this can be customized per search later)

Example:

"Timestamp, ServiceName, SeverityText, Body"

timestampValueExpression

string

required

DateTime column or expression that is part of your table's primary key.

Example:

"Timestamp"

string

Unique source ID. Server-generated; ignored if sent in create/update requests.

Example:

"507f1f77bcf86cd799439011"

section

string

Optional grouping label used to organize sources in the source selector. Sources that share a section value are displayed together.

Example:

disabled

boolean | null

When true, the source is hidden from source selectors in the UI. Defaults to false.

Example:

false

querySettings

object[]

Optional ClickHouse query settings applied when querying this source.

serviceNameExpression

string | null

Expression to extract the service name from log rows.

Example:

"ServiceName"

serviceVersionExpression

string | null

Expression identifying the running release of a service. Defaults to the OpenTelemetry service.version resource attribute when unset. Where services carry the release on different attributes, fall back across them with coalesce(nullIf(a, ''), nullIf(b, '')).

Example:

"ResourceAttributes['service.version']"

severityTextExpression

string | null

Expression to extract the severity/log level text.

Example:

"SeverityText"

traceIdExpression

string | null

Expression to extract the trace ID for correlating logs with traces.

Example:

"TraceId"

spanIdExpression

string | null

Expression to extract the span ID for correlating logs with traces.

Example:

"SpanId"

implicitColumnExpression

string | null

Column used for full text search if no property is specified in a Lucene-based search. Typically the message body of a log.

Example:

"Body"

knownColumnsListExpression

string | null

For Distributed table sources whose target tables have non-matching column sets. A list of columns supported across all target tables, used instead of SELECT * when fetching full row data. Leave blank to select all columns.

Example:

"Timestamp, Body, ServiceName"

useTextIndexForImplicitColumn

enum<string> | null

Controls whether lucene rendering uses ClickHouse text indices via hasAllTokens() against the implicit column. "auto" detects a covering index at query time, "enabled" forces text index usage, "disabled" forces a LIKE/hasToken fallback.

Available options:

auto,

enabled,

disabled

Example:

"auto"

highlightedTraceAttributeExpressions
