Data Connectors

Update connection

Update a connection’s settings or rotate its secrets. Fields omitted from the body are left unchanged; secrets are write-only.

A present snapshot_config replaces the stored policy, with one protection: on HTTP connections, omitting the http_replication key preserves the stored http_replication — clients that do not round-trip it cannot erase it. Include http_replication to replace it, or set it to null to clear it; other keys always reflect exactly what was sent. Omit snapshot_config entirely to leave the whole policy unchanged. http_replication is valid only for HTTP/REST connector types and must not be copied to dataset settings.

Authorizations

Authorization

string

header

required

The access token received from the authorization server in the OAuth 2.0 flow.

Path Parameters

connection_id

string

required

Body

application/json

name

string | null

Connection name, shown across Summation.

type

string | null

Source type, e.g. POSTGRES or SNOWFLAKE.

description

string | null

Optional human-readable description.

config

Config · object

Non-secret, type-specific settings. The accepted keys differ per type — GET /v1/connections/data/types/{type} lists them with which are required and a ready-to-send example. Postgres, for instance, takes pg_host, pg_port, pg_db, pg_user and pg_sslmode.

Example:

{
  "pg_db": "analytics",
  "pg_host": "db.example.com",
  "pg_port": "5432",
  "pg_user": "summation"
}

secrets

Secrets · object

Credentials, keyed the same way as config — see GET /v1/connections/data/types/{type} for the secret keys of a given type (Postgres: pg_pass). Stored server-side as secret refs; never returned by any response.

Example:

{ "pg_pass": "<password>" }

snapshot_config

Snapshot Config · object

Connector-level snapshot policy. Only HTTP/REST connections may set snapshot_config.http_replication; never put http_replication in connector config or dataset snapshot settings. The object accepts version=1, validate_server_address (optional; true is the only accepted value — server-address validation cannot be disabled through this API), connector-scoped limits, and resources. Each resource defines request_path; cursor, required for every INCREMENTAL_* sync strategy and optional for FULL_REFRESH, in formats RFC3339, STRING, or INTEGER; optional composite tie-breaker and DESTINATION_MAX or EXPLICIT bootstrap; pagination modes NEXT_LINK and TOKEN using JSON pointers, LINK_HEADER using the RFC 8288 Link response header, or KEYSET and OFFSET using query parameters (KEYSET requires a cursor); initial_query_parameters, which require a cursor; query_parameters containing ${cursor} and, for a composite cursor, ${tie_breaker}. A cursor-less resource rejects both placeholders, and may set constant query_parameters only under TOKEN or OFFSET pagination, where they are sent on every page; NEXT_LINK and LINK_HEADER follow a provider-built continuation URL and so reject query_parameters entirely. Optional source-to-destination field_mappings, tombstone, and execution_order. Data Management validates the complete configuration. Encode integers above 2^53-1 as strings (INTEGER-format cursor values are parsed back losslessly). PATCH semantics: a present snapshot_config replaces the stored policy, with one protection — on HTTP connections, omitting the http_replication key preserves the stored http_replication, so clients that do not round-trip it cannot erase it. Include http_replication to replace it, or set it to null to clear it. Omit the snapshot_config field entirely to leave the whole policy unchanged.
