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

Note the following when authenticating instances:

• The UI uses default application permissions when asking for access to your Salesforce applications. If you would like custom application permissions, you will need to create your own connected app and configure the application access in your custom UI. Follow the instructions in Salesforce Sales Cloud API Provider Setup.
• If you create a custom application, you will need to create instances via the APIs to use this new app. You only need to create this application once and you can use it for all of your customers.
• Once an instance is created we automatically refresh the token behind the scenes so that you will never have to connect your application again.

Authenticate Through the UI

Use the UI to authenticate with Salesforce and create a connector instance. Because you authenticate with Salesforce 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 Salesforce to authorize SAP Open Connectors access to your account. For more information about authenticating a connector instance, see Authenticate a Connector 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 common resource, or use it in a formula template.

Authenticate Through API

Authenticating through API is a multi-step 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 callback to the specified url with an authorization grant code.
• Authenticating the connector instance. Using the authorization code from the vendor, authenticate with the vendor to create a connector instance at SAP Open Connectors.

Getting a Redirect URL

Use the following API call to request a redirect URL where the user can authenticate with the vendor. Replace {keyOrId} with the connector key, sfdc.

GET /elements/{keyOrId}/oauth/url?apiKey=<api_key>&apiSecret=<api_secret>&callbackUrl=<url>&siteAddress=<url>

Query Parameters

Example cURL

curl -X GET
-H 'Content-Type: application/json'
'https://api.openconnectors.us2.ext.hana.ondemand.com/elements/api-v2/elements/sfdc/oauth/url?apiKey=fake_salesforce_api_key&apiSecret=fake_salesforce_api_secret&callbackUrl=https://www.mycoolapp.com/auth&state=sfdc'

Example Response

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

{
"element": "sfdc",
"oauthUrl": "https://login.salesforce.com/services/oauth2/authorize?response_type=code&client_id=fake_salesforce_api_key&client_secret=xyz789&scope=full%20refresh_token&redirect_uri=https://www.mycoolapp.com/auth&state=sfdc"
}

Authenticating Users and Receiving the Authorization Grant Code

Provide the response from the previous step to the users. After they authenticate, the endpoint provides an authorization grant code and state as query parameters, as shown in the example below.

https://<callbackurl>?code=xoz8AFqScK2ngM04kSSM&state=sfdc

Query Parameters

Authenticating the Connector Instance

Use the /instances endpoint to authenticate with Salesforce and create a connector instance. If you are configuring events, see the Events section.

To create a connector instance:

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

   {
     "element": {
       "key": "sfdc"
     },
     "providerData": {
       "code": "<AUTHORIZATION_GRANT_CODE>"
     },
     "configuration": {
       "oauth.callback.url": "<CALLBACK_URL>",
       "oauth.api.key": "<CONSUMER_KEY>",
       "oauth.api.secret": "<CONSUMER_SECRET>",
       "filter.response.nulls": true
     },
     "tags": [
       "<Add_Your_Tag>"
     ],
     "name": "<Insert_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 in the response and save it for all future requests using the connector instance.

Example cURL

curl -X POST \
  https://api.openconnectors.us2.ext.hana.ondemand.com/elements/api-v2/instances \
  -H 'authorization: User <USER_SECRET>, Organization <ORGANIZATION_SECRET>' \
  -H 'content-type: application/json' \
  -d '{
  "element": {
    "key": "sfdc"
  },
  "providerData": {
    "code": "xoz8AFqScK2ngM04kSSM"
  },
  "configuration": {
    "oauth.callback.url": "<CALLBACK_URL>",
    "oauth.api.key": "<CONSUMER_KEY>",
    "oauth.api.secret": "<CONSUMER_SECRET>"
  },
  "tags": [
    "For Docs"
  ],
  "name": "SFDCviaAPI1"
}'

Parameters

API parameters not shown in SAP Open Connectors are in code formatting.
