Autodesk Construction Cloud API and integration guide
Autodesk Construction Cloud (presented as part of the Autodesk Forma industry cloud brand since March 24, 2026) is reached through Autodesk Platform Services: REST APIs for issues, RFIs, submittals, cost, forms and files, with OAuth, webhooks and a Data Connector for bulk CSV extracts.

At a glance
- Category
- Project management · Autodesk
- API style
- REST/JSON through Autodesk Platform Services (APS).
- Authentication
- APS OAuth 2.0: two-legged (client credentials) and three-legged (authorization code), plus Secure Service Accounts for server-to-server apps. A customer account admin must add your app's client ID under Account Admin > Custom Integrations.
- Sandbox / developer program
- APS has a free tier covering cloud APIs, with monthly limits on select metered APIs. No separate construction sandbox confirmed; test in a project you control.
- Webhooks / events
- Yes, through the APS Webhooks API: Data Management events (such as new file versions) and issue events (created, updated, deleted and more), among others.
- Rate limits
- Published per service and endpoint; for example, Cost Management allows 5,000 requests per minute overall, and Data Management endpoints mostly fall between 50 and 800 per minute per client ID. Exceeding a limit returns 429 with Retry-After.
- Exports and files
- Data Connector API: scheduled or one-time CSV extracts (ZIP), up to 50 projects per request, with files available for 30 days.
- Marketplace / partner program
- Autodesk Developer Network (ADN); members can request rate-limit increases. App listing programs not confirmed.

Notes and gotchas
- Calls fail until the customer adds your client ID under Account Admin > Custom Integrations.
- Some admin (/hq/v1) endpoints accept two-legged tokens only, while user-scoped tools need three-legged ones; pick the token type per endpoint.
- From March 24, 2026, Autodesk presents ACC products under the Forma industry cloud brand and renames some items (ACC [functionality] API became Forma [functionality] API), but says URLs, logins, APIs and integrations are unchanged, so expect mixed naming in docs.

Frequently asked questions
Is Autodesk Construction Cloud now Autodesk Forma?
Not renamed outright. From March 24, 2026, Autodesk represents ACC products as part of the Forma industry cloud brand and renames some items (for example, ACC Account Admin became Forma Hub Admin, and ACC APIs became Forma APIs). Autodesk says URLs, logins, APIs and integrations are unchanged.
Why does my APS app get 403 on an ACC project?
Usually because the account admin hasn't added your client ID under Account Admin > Custom Integrations, or the endpoint needs a different token type.
How do I get bulk ACC data into reporting?
The Data Connector API produces scheduled CSV extracts across up to 50 projects per request, which suits a nightly lakehouse load better than paging every endpoint.
