Parqet Connect API
Changelog
Track every change to the Parqet Connect API — new endpoints, breaking changes, deprecations and fixes.
A new read endpoint allows integrations to fetch the holdings of a specific portfolio, including asset-specific metadata and optional external IDs for reconciliation.
/portfolios/{portfolioId}/holdings- Added
GET /portfolios/{portfolioId}/holdingsnow returns holdings for the requested portfolio.
Custom holding creation now supports importing an initial set of quotes. User-managed quote imports can now overwrite existing quotes for the same datetime, simplifying idempotent sync runs.
/portfolios/{portfolioId}/holdings/custom- Added
POST /portfolios/{portfolioId}/holdings/customnow accepts an optionalquotesarray so integrations can import initial price history while creating a custom holding.
/portfolios/{portfolioId}/quotes/user-managed- Changed
POST /portfolios/{portfolioId}/quotes/user-managednow updates existing quotes when an incoming quote uses the same datetime instead of rejecting it.
User-managed quote creation now supports a structured identifier for both Parqet holding IDs and external source IDs.
Source-system IDs are useful when syncing from external brokers, because they provide stable cross-system mapping of resources.
The pre-existing holdingId property is now deprecated
/portfolios/{portfolioId}/quotes/user-managed- Added
POST /portfolios/{portfolioId}/quotes/user-managednow acceptsidentifier: { type: "holdingId" | "externalId", value }to target holdings by Parqet or source-system IDs. - Deprecated
The pre-existing
holdingIdfield is still accepted for backward compatibility, but it is deprecated; migrate toidentifier(for example,holdingId: "abc123"->identifier: { type: "holdingId", value: "abc123" }).
Holding creation endpoints now support source-system reconciliation IDs consistently. Custom holdings also accept an optional image payload to align with other holding types that already support logos.
/portfolios/{portfolioId}/holdings/custom- Added
externalIdis now supported when creating custom holdings. - Added
imageDatacan now be provided when creating custom holdings.
/portfolios/{portfolioId}/holdings/cash- Added
externalIdis now supported when creating cash holdings.
/portfolios/{portfolioId}/holdings/commodity- Added
externalIdis now supported when creating commodity holdings.
/portfolios/{portfolioId}/holdings/real-estate- Added
externalIdis now supported when creating real estate holdings.
/performance- Added
Performance responses now include
externalIdon holdings, allowing source-system reconciliation across read and write flows.
Sending cash in referenceAccountFor was previously accepted by the request schema but still failed during processing. The API now rejects this input during validation, which also results in improved type safety for clients.
/portfolios/{portfolioId}/holdings/cash- Fixed
POST /portfolios/{portfolioId}/holdings/cashnow returns a validation error whenreferenceAccountForcontainscash(previously this also errored later in processing).
Activities now support an optional externalId so integrations can map Parqet activities to source-system records (for example, broker transaction IDs). Use a stable ID per source activity to prevent duplicates and simplify sync logic.
/portfolios/{portfolioId}/activities- Added
externalIdcan now be provided when creating activities.
/portfolios/{portfolioId}/activities- Added
externalIdis now returned in activity responses, allowing clients to reconcile Parqet data with their original source records.
/portfolios/{portfolioId}/holdings/cash- Fixed
Provide explicit error message if duplicate reference accounts are created (only one reference account is allowed per asset class).
Performance responses now include chart series and richer commodity metadata.
/performance- Added
Response now includes a charts array with
mark,date, and time-series values (history,capitalHistory,perfHistory,perfHistoryUnrealized,ttwror,drawdown). - Added

RMBis no longer supported (useCNYinstead).
/portfolios/{portfolioId}/activities- Added
holding_idis now forwarded forcash,commodity,real_estate, andcustom_assetactivity payloads.

/portfolios/{portfolioId}/holdings/cash- Added
New endpoint to create cash holdings (with support for reference accounts).
/portfolios/{portfolioId}/holdings/commodity- Added
New endpoint to create commodity holdings (identifier + definition with unit, amount, purity).
/portfolios/{portfolioId}/holdings/real-estate- Added
New endpoint to create real estate holdings.
/portfolios/{portfolioId}/activities- Added
Activity creation now accepts
assetIdentifierTypevaluescash,commodity, andreal_estatewithholding_id.
/performance- Fixed
A 400 response is returned if absolute intervals have an
enddate before thestartdate.
