Getting started with External APIs

This page shows you how to make your first authenticated API call to UiPath. It uses the client credentials flow with a confidential external application — the recommended starting point for production scripts, administrative automation, and integration work.

Hinweis:

Choosing the right tool

The UiPath Swagger documentation lets you explore available API endpoints and understand request and response formats interactively in a browser. Use Swagger for discovery and manual testing only. For production automation, scripting, and integration, use Postman, cURL, or your application code — these support the full OAuth 2.0 bearer token flow required to authorize requests to UiPath APIs.

Voraussetzungen

• A UiPath organization administrator has registered a confidential external application with the Client Credentials grant type and assigned the required scopes to it.
• You have the App ID and App Secret for the registered application.

For information about registering external applications and choosing the right grant type, see External Applications (OAuth).

Step 1: Get a bearer token

Send a POST request to the Identity Server token endpoint to receive a bearer token.

curl -X POST "https://cloud.uipath.com/{organizationName}/identity_/connect/token" \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -d "grant_type=client_credentials&client_id={app_id}&client_secret={app_secret}&scope={scopes}"

Replace the following placeholders:

Platzhalter	Wert
{organizationName}	Your organization name as it appears in the Automation Cloud URL
{app_id}	The App ID from your external application registration
{app_secret}	The App Secret from your external application registration
{scopes}	Space-separated list of scopes granted to the application, for example: OR.Users.View PM.Users

The response returns a bearer token:

{
    "access_token": "{access_token}",
    "expires_in": 3600,
    "token_type": "Bearer",
    "scope": "{scopes}"
}

Copy the access_token value. The token is valid for one hour.

Hinweis:

If you are using Postman or a similar tool, set the request content type to application/x-www-form-urlencoded.

Step 2: Call an API endpoint

Include the bearer token in the Authorization header of your API request.

The following example retrieves a list of machines from Orchestrator:

curl -X GET "https://cloud.uipath.com/{organizationName}/{tenantName}/orchestrator_/odata/Machines" \
  -H "Authorization: Bearer {access_token}" \
  -H "accept: application/json"

Replace {tenantName} with the name of your Orchestrator tenant and {access_token} with the token from Step 1.

Ergebnis

A successful request returns HTTP 200 with the requested data in JSON format.

If the request fails, verify the following:

• The token has not expired. Tokens expire after one hour — repeat Step 1 to request a new token.
• The Authorization header value is formatted exactly as Bearer {access_token}.
• The scopes granted to your external application cover the requested endpoint. To find the scope values for a specific endpoint, check that endpoint's documentation page in this guide, specifically under the Platform Management APIs chapter.
