Create Harvest-Connected Nintex Workflows

Nintex Workflow Cloud is a cloud-based platform where you can design workflows to automate simple or complex processes using drag-and-drop interactions — without writing any code. When paired with CData Connect AI, you get instant, cloud-to-cloud access to Harvest data for business applications. This article shows how to create a virtual database for Harvest in Connect AI and build a simple workflow from Harvest data in Nintex.

CData Connect AI provides a pure, cloud-to-cloud interface for Harvest, allowing you to build workflows from live Harvest data in Nintex Workflow Cloud — without replicating the data to a natively supported database. Nintex allows you to access data directly using SQL queries. Using optimized data processing out of the box, CData Connect AI pushes all supported SQL operations (filters, JOINs, etc.) directly to Harvest, leveraging server-side processing to quickly return the requested Harvest data.

Configure Harvest Connectivity for Nintex

Connectivity to Harvest from Nintex is made possible through CData Connect AI. To work with Harvest data from Nintex, we start by creating and configuring a Harvest connection.

1. Log into Connect AI, click Sources, and then click Add Connection

2. Select "Harvest" from the Add Connection panel

3. Enter the necessary authentication properties to connect to Harvest.

   Start by setting the Profile connection property to the location of the Harvest Profile on disk (e.g. C:\profiles\Harvest.apip). Next, set the ProfileSettings connection property to the connection string for Harvest (see below).

   Harvest API Profile Settings

   To authenticate to Harvest, you can use either Token authentication or the OAuth standard. Use Basic authentication to connect to your own data. Use OAuth to allow other users to connect to their data.

   Using Token Authentication

   To use Token Authentication, set the APIKey to your Harvest Personal Access Token in the ProfileSettings connection property. In addition to APIKey, set your AccountId in ProfileSettings to connect.

   Using OAuth Authentication

   First, register an OAuth2 application with Harvest. The application can be created from the "Developers" section of Harvest ID.

   After setting the following connection properties, you are ready to connect:

   • ProfileSettings: Set your AccountId in ProfileSettings.
   • AuthScheme: Set this to OAuth.
   • OAuthClientId: Set this to the client ID that you specified in your app settings.
   • OAuthClientSecret: Set this to the client secret that you specified in your app settings.
   • CallbackURL: Set this to the Redirect URI that you specified in your app settings.
   • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage how the driver obtains and refreshes the OAuthAccessToken.
   
4. Click Save & Test
5. Navigate to the Permissions tab in the Add Harvest Connection page and update the User-based permissions.

Add a Personal Access Token

When connecting to Connect AI through the REST API, the OData API, or the Virtual SQL Server, a Personal Access Token (PAT) is used to authenticate the connection to Connect AI. It is best practice to create a separate PAT for each service to maintain granularity of access.

1. Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
2. On the Settings page, go to the Personal Access Tokens section and click Create PAT.
3. Give the PAT a name and click Create.
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

With the connection configured and a PAT generated, you are ready to connect to Harvest data from Nintex Workflow Cloud.

Connect to Harvest from Nintex

The steps below outline creating a new connection to Harvest data from Nintex (via Connect AI).

1. Log into Nintex Workflow Cloud
2. In the Connections tab, click "Add new"
3. Select "Microsoft SQL Server" as the connector and click "Connect"
4. In the SQL Server connection wizard, set the following properties:
   • Connection Name: Connect AI
   • Username: a Connect AI username (e.g. [email protected])
   • Password: the Connect AI user's PAT
   • Database Host: tds.cdata.com:14333
   • Database Name: the Harvest connection (a.g., API1)
   
5. Click "Connect"
6. Configure the connection permissions and click "Save permissions"

Create a Simple Harvest Workflow

With the connection to CData Connect AI configured, we are ready to build a simple workflow to access Harvest data. Start by clicking the "Create workflow" button.

Configure the Start Event Action

1. Click the start event task and select the "Form" event
2. Click "Design form"
3. Drag a "Text - Long" element onto the Form and click the element to configure it
   • Set "Title" to "Enter SQL query"
   • Set "Required" to true
4. Drag a "Text - Short" element onto the Form and click the element to configure it
   • Set "Title" to "Enter desired result column"
   • Set "Required" to true

Configure an "Execute a Query" Action

1. Add an "Execute a query" action after the "Start event: Form" action and click to configure the action
2. Set "SQL Script" to the "Enter SQL Query" variable from the "Start event" action
3. Set "Column to retrieve" to the "Enter desired result column" variable from the "Start event" action
4. Set "Retrieved column" to a new variable (a.g., "values")

Configure a "Send an Email" Action

1. Add a "Send an email" action after the "Execute a query" action and click to configure the action
2. Set the "Recipient email address"
3. Set the "Subject"
4. Set the "Message body" to the variable created for the retrieved column

Once you configure the actions, click "Save," name the Workflow, and click "Save" again. You now have a simple workflow that will query Harvest using SQL and sand an email with the results.
