Authenticate with Revel

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

Authenticate Through the UI

Use the UI to authenticate with Revel and create an element instance. Revel authentication follows the typical OAuth 2.0 framework and you will need to sign in to Revel as part of the process.

If you are configuring events, see the Events section.

To authenticate an element instance:

1. Sign in to Cloud Elements, and then search for Revel in our Elements Catalog.
2. Hover over the element card, and then click Authenticate.
3. Enter a name for the element instance.
4. In Subdomain, enter the unique subdomain part of your Revel URL. For example, if your url is https://cloud-elements.revelup.com, enter cloud-elements.
5. Optionally type or select one or more Element Instance Tags to add to the authenticated element instance.
6. Click Create Instance.
7. Provide your Revel credentials, and then allow the connection.

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:

• Getting a redirect URL. This URL sends users to the vendor to log in to their account.
• Authenticating users and receiving the authorization grant code. After the user logs in, the vendor makes a call back to the specified url with an authorization grant code.
• Authenticating the element instance. Using the authorization code from the vendor, authenticate with the vendor to create an element instance at Cloud Elements.

Getting a Redirect URL

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, revel.

curl -X GET /elements/{keyOrId}/oauth/url?apiKey=<api_key>&apiSecret=<api_secret>&callbackUrl=<url>&siteAddress=<url>&subdomain=<yourSubDomain>

Query Parameters

Example cURL

curl -X GET \
  'https://api.cloud-elements.com/elements/api-v2/elements/revel/oauth/url?apiKey=123xxxxxxxxx&apiSecret=456xxxxxxxxxxxx&callbackUrl=https://www.mycoolapp.com/auth&subdomain=cloud-elements&subdomain=cloud-elements' \

Example Response

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

{
"oauthUrl": "https://cloud-elements.revelup.com/external/authenticate/?callback=https%3A%2F%2Fauth.cloudelements.io%2Fget%3Fcode%3D123",
"element": "revel"
}

Authenticating Users and Receiving the Authorization Grant Code

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

• code
• token

Authenticating the Element Instance

Use the /instances endpoint to authenticate with Revel and create an element instance. If you are configuring events, see the Events section.

To authenticate an element instance:

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

   {
     "element": {
       "key": "revel"
     },
     "providerData": {
       "code": "<AUTHORIZATION_GRANT_CODE>",
       "token": "<TEMPORARY_TOKEN_FROM_PREVIOUS_STEP"
     },
     "configuration": {
       "oauth.callback.url": "<Revel API Key >",
       "oauth.api.key": "<Revel API Secret>",
       "oauth.api.secret": "<Callback URL Name>",
       "subdomain": "testhumanity"
   
     },
     "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. See the Overview for details.

3. Locate the token and id in the response and save them for all future requests using the element instance.

Example cURL

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": "revel"
  },
  "providerData": {
    "code": "xxx"
    "token": "xxxxxxxxxxxxxxxxxx"
  },
  "configuration": {
    "oauth.callback.url": "https;//mycoolapp.com",
    "oauth.api.key": "xxxxxxxxxxxxxxxxxx",
    "oauth.api.secret": "xxxxxxxxxxxxxxxxxxxxxxxx",
    "subdomain": "cloud-elements"
  },
  "tags": [
    "Docs"
  ],
  "name": "API Instance"
}'

Parameters

API parameters not shown in Cloud Elements are in code formatting.

Example Response for an Authenticated Element Instance

In this example, the instance ID is 12345 and the instance token starts with "ABC/D...". The actual values returned to you will be unique: make sure you save them for future requests to this new instance.
