Onshape Part API declares
2 security schemes
for authenticating requests.
It supports OAuth 2.0 (OAuth2) using the authorizationCode flow, exposing 24 scopes.
It accepts HTTP basic authentication (BasicAuth).
By default, every request must be authenticated.
OAuth2 — Use OAuth 2.0 to authenticate requests.
BasicAuth — Use Basic Authentication with API Keys (key as username and secret as password) to authenticate requests.
Paths & Operations 12
Across 12 paths, the API surfaces 12 operations — 12 GET. Each is listed below with its method, path, parameters, and response codes.
Part 12
Export Parts and access Part details.
GET
/parts/d/{did}/{wvm}/{wvmid}
Get all parts in a workspace, version, or microversion.
The contract defines 148 schemas that model the data the API accepts and returns. The most detailed are BTPartStudioDisplayData-346 (40 properties), BTPartMetadataInfo (35 properties), BTPartData-16 (30 properties), BTPartDisplayData-17 (28 properties). Each schema is shown below with its type and property counts.

ⓘWhere this information came from
This is an independent, third-party profile of Onshape Part API, published by
API Evangelist. We do not operate, host, resell, or
support these APIs, and we are not affiliated with or endorsed by the company unless stated above.
Everything here is built from publicly available information — the company's own site,
developer portal, documentation, public repositories, and the specifications it publishes for public use.
Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's
public API artifacts, scored against a published rubric. They are not certifications,
endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and
you do not need to justify the request. A removed company is recorded as unrated, never scored
zero for having asked. Acknowledgement within one business day; removal within two.
