Chapter 2. Implementing the Twitter to Salesforce sample integration

This sample integration watches Twitter for tweets that mention a particular Twitter user. When the integration finds such tweets, it filters them so that only those tweets that contain the text that you specify cause the integration to continue.

For tweets that contain the specified text, the integration passes data related to the tweet, including the Twitter user name, to Salesforce and Salesforce creates a new contact.

Prerequisites

  • You need a Twitter developer account. If you do not already have one, go to https://apps.twitter.com, sign in to Twitter, and click Apply for a developer account. Obtaining the developer account is quick when you provide a professional email address, such as me@redhat.com rather than a personal address such as you@gmail.com.
  • You need an account in a Salesforce installation that is used for development. This account must have Salesforce API access, which is available in a Salesforce Enterprise account or a Salesforce Developer account. To obtain a free developer account, visit https://developer.salesforce.com/signup. It takes less than two minutes to obtain a Salesforce account.
  • You must be logged in to your Fuse Online environment.

To implement, deploy, and test this sample integration, the main steps are:

  1. Section 2.1, “Registering Fuse Online as a Twitter client application”
  2. Section 2.2, “Creating a Twitter connection”
  3. Section 2.3, “Registering Fuse Online as a Salesforce client application”
  4. Section 2.4, “Creating a Salesforce connection”
  5. Section 2.5, “Creating and deploying the Twitter to Salesforce sample integration”
  6. Section 2.6, “Confirming that the Twitter to Salesforce integration works”
  7. Section 2.7, “Cleaning up your integration”

2.1. Registering Fuse Online as a Twitter client application

In an integration, to connect to Twitter, the first thing you must do is register your Fuse Online environment as a client application that can access Twitter. This lets you create any number of integrations that connect to Twitter. In other words, you need to register a particular Fuse Online environment with Twitter only once.

In each Fuse Online environment, there can be only one registration of Fuse Online as a Twitter client application. However, while each Twitter connection uses the same registration, it can use different user credentials.

Prerequisite

You are logged in to Fuse Online.

2.5. Creating and deploying the Twitter to Salesforce sample integration

To create and deploy an integration that uses the Twitter and Salesforce connections that you created, the main steps are:

Prerequisites

  • You registered your Fuse Online environment as a Twitter client and created a Fuse Online Twitter connection.
  • You registered your Fuse Online environment as a Salesforce client and created a Fuse Online Salesforce connection.
  • Fuse Online is open and you are logged in.

2.5.1. Choosing the start connection

In Fuse Online, to create the sample Twitter to Salesforce integration, the first task is to choose the start connection.

Prerequisites

  • You created a Twitter connection.

Procedure

  1. On the left, click Integrations.
  2. Click Create Integration.
  3. On the Choose a connection page, click the Twitter connection that you created. If you gave it the example name, you would click Twitter Connect 1. When the integration starts, it uses the credentials defined in this connection to connect to Twitter.
  4. On the Choose an action page, to the right of the Mention action entry, click Select.
  5. On the Configure the action page, click Next. No configuration is required.

Next step

When the integration is running, after connecting to Twitter, the integration monitors Twitter for mentions that include your Twitter screen name. A match triggers the next step in the integration. However, before you add steps that operate on data between connections, you choose the connection that the integration uses to finish its work.

2.5.2. Choosing the finish connection

In Fuse Online, to continue creating the Twitter to Salesforce sample integration, after you add the start connection, you add the finish connection to the integration.

Prerequisites

  • You added the Twitter connection to the integration as the start connection.
  • Fuse Online is prompting you to add the finish connection.
  • You created a Salesforce connection.

Procedure

  1. On the Choose a connection page, click the Salesforce connection that you created. If you gave it the example name, you would click SF Connect 1. This integration finishes by using the credentials defined in this connection to connect to Salesforce.
  2. On the Choose an action page, to the right of the New record entry, click Select.
  3. On the Configure the action page, click in the Object name field and select Contact as the Salesforce record to create.
  4. Click Next to add the finish connection to the integration.

2.5.3. Adding a basic filter step

In Fuse Online, to continue creating the Twitter to Salesforce sample integration, add a basic filter step that checks tweets that mention you for particular content. At integration execution time, processing continues only if that content is present.

Prerequisites

  • You added the Twitter connection as the integration’s start connection.
  • You just added the Salesforce connection as the integration’s finish connection.

Procedure

  1. In the integration visualization, click the plus sign, which displays the steps that you can add to the integration.
  2. Click Basic Filter.
  3. In the Property Name field, start to enter text and when text appears below the field, click it. The Twitter text field, which contains a tweet, is the data that you want the filter to evaluate.
  4. In the Operator field, accept contains as the condition to be met for the integration to continue.
  5. In the Keywords field, enter #RedHatIsGreat or some other text that you choose for the value to check for. A tweet that mentions you must contain the text you enter here for the integration to continue operating on this data.
  6. Click Done to add the basic filter step to the integration.

2.5.4. Adding a data mapping step

To continue creating the Twitter to Salesforce sample integration, add a data mapping step that correlates Twitter mention fields to Salesforce contact fields.

Prerequisites

  • The integration’s start connection is to Twitter.
  • The integration’s finish connection is to Salesforce.
  • You just added the filter step between the two connections.

Procedure

  1. In Fuse Online, in the integration visualization, click the plus sign that is between the filter step and the finish connection.
  2. Click Data Mapper and wait a few moments. When the data fields appear, the Sources panel on the left displays the Twitter fields and the Target panel on the right displays the Salesforce fields.

  3. Map the Twitter name field to the Salesforce FirstName and LastName fields:
