Register OAuth integration

Create an integration in the developer portal to obtain Client ID and Client Secret.

Sign in to your Nmbrs developer portal.

  • Navigate to the My Integrations tab and click Create new integration.

On the Details tab, provide the integration metadata and the StackOne redirect URL, then click Save.

  • App name: e.g. stackone-nmbrs
  • App description: short description of the integration
  • Application type: select Web
  • Icon URL: a public image URL for the integration icon
  • Redirect URLs: add [https://api.stackone.com/connect/oauth2/nmbrs/callback](https://api.stackone.com/connect/oauth2/nmbrs/callback) — it must match exactly. The OAuth flow rejects redirect URIs that aren't registered.
  • Click Save.

Open the Secrets tab. The Client ID is shown at the top — copy it. Then click Generate Secret and copy the secret value immediately.

  • The Client Secret is shown only once on generation — store it securely; you cannot retrieve it later.

Available OAuth scopes

Nmbrs grants every integration access to the full scope catalog — there is no per-integration scope allowlist in the Nmbrs portal (the Helper tab only previews scopes for an example authorize URL). Pick the scopes your StackOne connection should request from the list below. Always include offline\_access so the connection can be kept alive past the 1-hour access-token expiry.
