SAP Business Objects REST by LaunchBI Authenticate an Element

On this page

You can authenticate with LaunchBI to create your own instance of the SAP Business Objects REST by LaunchBI element through the UI or through APIs. Once authenticated, you can use the element instance to access the different functionality offered by the LaunchBI platform.

Authenticate Through the UI

Use the UI to authenticate with LaunchBI and create an element instance. Because you authenticate with LaunchBI via OAuth 2.0, all you need to do is add a name for the instance. After you create the instance, you'll log in to LaunchBI to authorize Cloud Elements access to your account. For more information about authenticating an element instance, see Authenticate an Element Instance (UI)

After successfully authenticating, we give you several options for next steps. Make requests using the API docs associated with the instance, map the instance to a virtual data resource, or use it in a formula template.

Authenticate Through API

Authenticating through API is similar to authenticating via the UI. Instead of clicking and typing through a series of buttons, text boxes, and menus, you will instead send a request to our /instances endpoint. The end result is the same, though: an authenticated element instance with a token and id.

Authenticating through API follows a multi-step OAuth 2.0 process that involves:


1
Redirect URL




2
Authenticate Users




3
Authenticate Instance


Getting a Redirect URL


1
Redirect URL




2
Authenticate Users




3
Authenticate Instance


Use the following API call to request a redirect URL where the user can authenticate with the service provider. Replace {keyOrId} with the element key, sapborestbylaunchbi.

curl -X GET /elements/{keyOrId}/oauth/url?apiKey=<LaunchBI Inventory Key (Client ID)>&apiSecret=<LaunchBI Client Secret> &callbackUrl=<LaunchBI Callback URL>

Query Parameters

Query ParameterDescription
apiKeyThe API key or client ID obtained from registering your app with the provider. This is the Inventory Key (Client ID) that you recorded in API Provider Setup.
apiSecretThe client secret obtained from registering your app with the API provider. This is the Client Secret that you recorded in API Provider Setup.
callbackUrlThe URL that the API provider returns a user to after they authorize access. This is the Callback URL that you recorded in API Provider Setup.

Example Request

curl -X GET \
'https://api.cloud-elements.com/elements/api-v2/elements/sapborestbylaunchbi/oauth/url?apiKey=Rand0MAP1-key&apiSecret=fak3AP1-s3Cr3t&callbackUrl=https:%3A%2F%2Fwww.mycoolapp.com%2auth' \

Example Response

Use the oauthUrl in the response to allow users to authenticate with the vendor.

{
"oauthUrl": "https://launchbi.launchworks.com/launchbi/OAuth2/authorize?response_type=code&redirect_uri=https://auth.cloudelements.io/oauth&state=sapborestbylaunchbi&client_id=Rand0MAP1-key",
"element": "sapborestbylaunchbi"
}

Authenticating Users and Receiving the Authorization Grant Code


1
Redirect URL




2
Authenticate Users




3
Authenticate Instance


Provide the oauthUrl in the response from the previous step to the users. After users authenticate, LaunchBI provides the following information in the response:

  • code
  • state
Response ParameterDescription
codeThe authorization grant code returned from the API provider in an OAuth 2.0 authentication workflow. Cloud Elements uses the code to retrieve the OAuth access and refresh tokens from the endpoint.
stateA customizable identifier, typically the element key (sapborestbylaunchbi) .
Note: If the user denies authentication and/or authorization, there will be a query string parameter called error instead of the code parameter. In this case, your application can handle the error gracefully.

Authenticating the Element Instance

Redirect URL




2
Authenticate Users




3
Authenticate Instance


Use the code from the previous step and the /instances endpoint to authenticate with LaunchBI and create an element instance.

Note: The endpoint returns an element instance token and id upon successful completion. Retain the token and id for all subsequent requests involving this element instance.

To authenticate an element instance:

  1. Construct a JSON body as shown below (see Parameters):

    {
      "element": {
        "key": "sapborestbylaunchbi"
      },
      "providerData": {
        "code": "<AUTHORIZATION_GRANT_CODE>"
      },
      "configuration": {
        "oauth.api.key": "<LaunchBI Inventory Key (Client ID)>",
        "oauth.api.secret": "<LaunchBI Client Secret>",
        "oauth.callback.url": "<LaunchBI Callback URL >"
      },
      "tags": [
        "<Add_Your_Tag>"
      ],
      "name": "<INSTANCE_NAME>"
    }
    
  2. Call the following, including the JSON body you constructed in the previous step:

    POST /instances
    
    Note: Make sure that you include the User and Organization keys in the header. For more information, see Authorization Headers, Organization Secret, and User Secret.
  3. Locate the token and id in the response and save them for all future requests using the element instance.

Example Request

curl -X POST \
  https://api.cloud-elements.com/elements/api-v2/instances \
  -H 'authorization: User <USER_SECRET>, Organization <ORGANIZATION_SECRET>' \
  -H 'content-type: application/json' \
  -d '{
  "element": {
    "key": "sapborestbylaunchbi"
  },
  "providerData": {
    "code": "xxxxxxxxxxxxxxxxxxxxxxx"
  },
  "configuration": {
    "oauth.api.key": "Rand0MAP1-key",
    "oauth.api.secret": "fak3AP1-s3Cr3t",
    "oauth.callback.url": "https://mycoolapp.com"
  },
  "tags": [
    "Docs"
  ],
  "name": "API Instance"
}'
