For BIM 360 account-admin endpoints (`/hq/v1/accounts/...`), the APS Client ID must be provisioned on the target BIM 360 account as a Custom Integration. Without this step, account-admin actions will return `403 Forbidden`.

Sign in to the BIM 360 Account Admin portal.

  • You must be an account administrator to complete this step.
The BIM 360 Account Admin Settings page showing the Profile tab with Account Information, APS Dev. Hub link, and View Account ID.

Click Settings in the top navigation bar, then select Custom Integrations.

  • Click Add Custom Integration.
  • Step 1 — Select Access: check BIM 360 Account Administration and click Next.
  • Step 2 — Select I'm the developer or Invite a developer, then click Next.
  • Step 3 — If you selected Invite a developer, enter the developer's email address and click Next. Otherwise, skip this step.
  • Step 4 — Paste the Client ID you copied from the APS portal.
  • Name the integration (e.g. `StackOne Integration App`).
  • You can also copy the Account ID displayed in this dialog for the next step.
  • Click Save.
The Add Custom Integration dialog showing Step 1 — Select Access with BIM 360 Account Administration checked.

While in the BIM 360 Account Admin portal, copy your account ID — you will need it in the next step.

  • Navigate to Settings → Profile → click View Account ID to see your account ID directly.
  • Alternatively, look at your browser's address bar — the account ID is the UUID after `/admin/` in the URL (e.g. `https://admin.b360.autodesk.com/admin/{accountId}/settings`).
  • Example: `b98421c2-caf6-45a1-a93f-98dfa1f34362`

Find your data region

Your data region identifies the Autodesk data centre where your BIM 360 / ACC / Forma account is hosted. Sign in to your BIM 360 Account Admin or ACC portal and check your browser address bar — the domain identifies the region.

  • United States — `acc.autodesk.com` → `US`
  • Canada — `acc.can.autodesk.com` → `CAN`
  • Europe — `acc.autodesk.eu` → `EMEA`
  • United Kingdom — `acc.gbr.autodesk.com` → `GBR`
  • Germany — `acc.deu.autodesk.com` → `DEU`
  • India — `acc.ind.autodesk.com` → `IND`
  • Japan — `acc.jpn.autodesk.com` → `JPN`
  • Australia — `acc.aus.autodesk.com` → `AUS`
  • See the ACC regions reference for the full list.

Linking the Account from the Hub

Use one of the three Linking Account Methods to access the Hub. Fill out the following fields using details from your provider:
  • Account ID
  • Data Region
  • Click Connect
  • If applicable, the provider will redirect you to a sign-in or authorization page. Complete the provider's authorization flow.
  • Once authorization is successful, you will see a confirmation popup

If the account linking is successful, you will see the newly linked account in your Accounts page.
