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

Authenticate Through the UI

Use the UI to authenticate with Evernote and create a connector instance as described in Authenticate a Connector Instance (UI). In addition to the base authentication parameters, you will need the credentials that you identified in API Provider Setup.

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 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 instance endpoint. The end result is the same, though: an authenticated connector instance with a token and id.

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

• Getting an OAuth token. Request the token and secret to be used in later steps.
• Getting an OAuth URL. Use the token from the previous step to request a URL to redirect your users to. After they authenticate through this URL, you receive and oauth_token and oauth_verifier to use in the next step.
• Authenticating the connector instance. Using the secret returned in step one, along with the oauth_token and oauth_verifier returned in step two to authenticate with the API Provider to create a connector instance at SAP Open Connectors.

Getting an OAuth Token

Use the following API call to request a secret and token. Replace {keyOrId} with the connector key, evernote.

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

Query Parameters

Example cURL

curl -X GET \
'https://api.openconnectors.us2.ext.hana.ondemand.com/elements/api-v2/elements/evernote/oauth/token?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.

{
    "secret": "4006B6SU5ZJ55RBUWN58OZVPE",
    "token": "evernoteALG86K3XCI190U9VDER7FDSI4MAGPRF0161RPQYBALG86K3XCI190U9VDER7ALG86K3XCI190U9VDER7"
}

Getting an OAuth URL

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

GET /elements/{keyOrId}/oauth/url?apiKey=<api_key>&apiSecret=<api_secret>&callbackUrl=<url>&siteAddress=<url>&scope=false&requestToken=<oauth_token RECEIVED IN PREVIOUS STEP>

Query Parameters

Example cURL

curl -X GET
-H 'Content-Type: application/json'
'https://api.openconnectors.us2.ext.hana.ondemand.com/elements/api-v2/elements/evernote/oauth/url?apiKey=fake_api_key&apiSecret=fake_api_secret&callbackUrl=https://httpbin.org/get&scope=false&requestToken=evernoteALG86K3XCI190U9VDER7FDSI4MAGPRF0161RPQYBALG86K3XCI190U9VDER7ALG86K3XCI190U9VDER7'

Example Response

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

{
  "oauthUrl": "https://sandbox.evernote.com/OAuth.action?oauth_token=evernoteALG86K3XCI190U9VDER7FDSI4MAGPRF0161RPQYBALG86K3XCI190U9VDER7ALG86K3XCI190U9VDER7",
  "element": "box"
}

Authenticating the Connector Instance

Use the secret from step one and the oauth_token and oauth_verifier returned in step two to make a request to the /instances endpoint to authenticate a connector instance.

To authenticate a connector instance:

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

     {
       "element": {
         "key": "evernote"
       },
       "providerData": {
         "secret": "<From Step 1>",
         "oauth_token": "<From Step 1>",
         "oauth_verifier": "<From Return URL>"
       },
       "configuration": {
         "oauth.api.key": "<INSERT_EVERNOTE_CONSUMER_KEY>",
         "oauth.api.secret": "<INSERT_EVERNOTE_CONSUMER_SECRET>",
         "oauth.request.url": "https://evernote.com",
         "oauth.callback.url": "<INSERT_CALLBACK_URL>",
         "evernote.sandbox": "https://sandbox.evernote.com"
       },
       "tags": [
         "<INSERT_TAGS>"
       ],
       "name": "<INSERT_INSTANCE_NAME>"
     }
   

   {
     "element": {
       "key": "evernote"
     },
     "providerData": {
       "secret": "<From Step 1>",
       "oauth_token": "<From Step 1>",
       "oauth_verifier": "<From Return URL>"
     },
     "configuration": {
       "oauth.api.key": "<Evernote app Consumer Key>",
       "oauth.api.secret": "<Evernote app Consumer Secret>",
       "oauth.callback.url": "<Evernote app Callback URL Name >",
       "oauth.request.url": "<https://evernote.com or https://sandbox.evernote.com>",
       "evernote.sandbox": "<true or false>"
     },
     "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 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": "evernote"
  },
  "providerData": {
    "secret": "15D1CFxxxxxxxxxxxxxxxxxxxxxx",
    "oauth_token": "evernoteALG86K3XCI190U9VDER7FDSI4MAGPRF0161RPQYBALG86K3XCI190U9VDER7ALG86K3XCI190U9VDER7",
    "oauth_verifier": "Dxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
  },
  "configuration": {
    "oauth.callback.url": "https;//mycoolapp.com",
    "oauth.api.key": "xxxxxxxxxxxxxxxxxx",
    "oauth.api.secret": "xxxxxxxxxxxxxxxxxxxxxxxx",
    "oauth.request.url": "https://sandbox.evernote.com",
    "evernote.sandbox": "true"
  },
  "tags": [
    "Docs"
  ],
  "name": "API Instance"
}'
