API Access

Overview

Data Service Open API allows you to manage UiPath Data Service resources from an external application of your choice, and does so by enabling you to authorize the external app without sharing any credentials, through the Oauth 2.0 authorization framework.

Learn how to register the external application in UiPath Automation Suite.

API Permissions

To use the Data Service OpenAPI, you must grant API permissions to the external application. These API permissions are known as scopes, and there are three types for Data Service:

• DataService.Schema.Read - this User Scope allows your external app to read your tenant's Data Service schema, and it's dependent on the user's permissions.
• DataService.Data.Read - this User Scope allows your external app to read your tenant's Data Service data, and it's dependent on the user's permissions.
• DataService.Data.Write - this User Scope allows your external app to edit your tenant's Data Service data by deleting, updating or creating new data, and it's dependent on the user's permissions.

Download the OpenAPI Specification

With your external application and the user permissions set, it's time to download the OpenAPI specification of your tenant's Data Service data. Do so by navigating to the top-right menu on the tenant's Data Service tab > API Access > Download OpenAPI file (JSON).

This will get you the OpenAPI 3.0 specifications of your tenant's Data Service entities, in JSON format. Clicking Copy OpenAPI link copies the API endpoint that generates the tenant's Data Service OpenAPI specification.

Authorizing the API Calls

Authorize your external application to use the Data Service OpenAPI by creating an access token for your external application. Use the App ID and App Secret that were generated at the external application registration. The authorization method depends on the application's type (confidential or non-confidential).

API Endpoints

OAuth2.0 authorization framework helps you generate a access token that allows your external application to make REST API calls to Data Service endpoints, for a limited time (one hour). To continue calling the APIs you need to generate a new access token or request a refresh token.

A Data Service API endpoint has the following syntax:

• HTTP method + BaseURL + The resource category + The Data Service entity + The Operation + Path variables and query parameters

  
  

  

  
  
  Important:

  In the Automation Suite-deployed Data Service, each active connection can have only one active file upload API call.

  To prevent running into this API limitation, make sure to pass the Connection: close header in your request.

  Data Service Entity Example

  To describe each API request/response body, we are using the Olympics entity fields created in the Data Service. While we document the generic endpoint, such as Get Entity Records, your endpoint contains the exact name of your entity (for example, Get Olympics Records). The response and request bodies include all the fields from your entity, replicating the entity's structure.
