Gmail Connector for SSIS

Read / search Gmail messages, download attachments, send mail and more using Gmail REST API.

In this article you will learn how to quickly and efficiently integrate Gmail data in SSIS without coding. We will use high-performance Gmail Connector to easily connect to Gmail and then access the data inside SSIS.

Let's follow the steps below to see how we can accomplish that!

Download Documentation

Gmail Connector for SSIS is based on ZappySys API Connector Framework which is a part of SSIS PowerPack. It is a collection of high-performance SSIS connectors that enable you to integrate data with virtually any data provider supported by SSIS, including SQL Server. SSIS PowerPack supports various file formats, sources and destinations, including REST/SOAP API, SFTP/FTP, storage services, and plain files, to mention a few (if you are new to SSIS and SSIS PowerPack, find out more on how to use them).

Prerequisites

Before we begin, make sure the following prerequisites are met:

SSIS designer installed. Sometimes it is referred as BIDS or SSDT (download it from Microsoft).
Basic knowledge of SSIS package development using Microsoft SQL Server Integration Services.
SSIS PowerPack is installed (if you are new to SSIS PowerPack, then get started!).

Read data from Gmail in SSIS (Export data)

In this section we will learn how to configure and use Gmail Connector in API Source to extract data from Gmail.

Begin with opening Visual Studio and Create a New Project.
Select Integration Service Project and in new project window set the appropriate name and location for project. And click OK.

In the new SSIS project screen you will find the following:
- SSIS ToolBox on left side bar
- Solution Explorer and Property Window on right bar
- Control flow, data flow, event Handlers, Package Explorer in tab windows
- Connection Manager Window in the bottom
Note: If you don't see ZappySys SSIS PowerPack Task or Components in SSIS Toolbox, please refer to this help link.
Now, Drag and Drop SSIS Data Flow Task from SSIS Toolbox. Double click on the Data Flow Task to see Data Flow designer.
From the SSIS toolbox drag and API Source (Predefined Templates) on the data flow designer surface, and double click on it to edit it:
Select New Connection to create a new connection:
Use a preinstalled Gmail Connector from Popular Connector List or press Search Online radio button to download Gmail Connector. Once downloaded simply use it in the configuration:

Gmail

Now it's time to configure authentication. Firstly, configure authentication settings in Gmail service and then proceed by configuring API Connection Manager. Start by expanding an authentication type:

User Account

Gmail authentication

To make this work you will have to create a Google Cloud project. This project forms the basis for creating, enabling, and using all Google Cloud services, including managing APIs, enabling billing, adding and removing collaborators, and managing permissions.

Go to the Google Cloud Console
In the Google Cloud console, go to menu IAM & Admin, and then Create a Project.
Enter the name of the new project into the Project Name field and select the appropriate organization, then click Create.
The console navigates to the Dashboard page and your project is created within a few minutes.
In the Google Cloud console, go to menu More products, Google Workspace, and then Product Library.
Now we need to enable the Gmail API.
Search for Gmail API. Select it and then click ENABLE.
Select the Credentials tab on the left side of the screen.
Select the + CREATE CREDENTIALS link to reveal a drop down menu.
In the dropdown menu, select OAuth client ID.
If presented, click the CONFIGURE CONSENT SCREEN button and then elect the appropriate User Type based on your business needs. Otherwise, continue to step 16.
In the OAuth consent screen tab fill in your app's website and domain information, and then click SAVE AND CONTINUE.
In the Scopes section of the app registration, click ADD OR REMOVE SCOPES and add the following scopes:
- openid
- https://mail.google.com/
- https://www.googleapis.com/auth/userinfo.email
- https://www.googleapis.com/auth/userinfo.profile
- https://www.googleapis.com/auth/gmail.labels
- https://www.googleapis.com/auth/gmail.send
- https://www.googleapis.com/auth/gmail.modify
- https://www.googleapis.com/auth/gmail.compose
- https://www.googleapis.com/auth/gmail.readonly
After the scopes have been added, click SAVE AND CONTINUE.
Complete the wizard setting up scopes.
Select the Credentials tab on the left side of the screen.
Select the + CREATE CREDENTIALS link to reveal a drop down menu.
In the dropdown menu, select OAuth client ID.
In the Application type drop down, select Desktop application and then give your app client a name.
Select the CREATE button.
A popup window will appear that provides important information you should record for your records:
- Client ID
- Client secret
And then click OK.
Go to OAuth Consent Screen tab. Under Publishing Status click PUBLISH APP to ensure your refresh token doesnt expire often. If you planning to use App for Private use then do not have to worry about Verification Status after Publish.
Back to Connection UI, Enter the client ID and client secret into the required parameters.

That's it! We are done! Just in a few clicks we configured the call to Gmail using Gmail Connector.

You can load the source data into your desired destination using the Upsert Destination , which supports SQL Server, PostgreSQL, and Amazon Redshift. We also offer other destinations such as CSV , Excel , Azure Table , Salesforce , and more . You can check out our SSIS PowerPack Tasks and components for more options.

Load Gmail data into SQL Server using Upsert Destination (Insert or Update)

Once you configured the data source, you can load Gmail data into SQL Server using Upsert Destination.

Upsert Destination can merge or synchronize source data with the target table. It supports Microsoft SQL Server, PostgreSQL, and Redshift databases as targets. Upsert Destination also supports very fast bulk upsert operation along with bulk delete.

Upsert operation - a database operation which performs INSERT or UPDATE SQL commands based on record's existence condition in the target table. It inserts records that don't have matching records in the target table or updates them, if they do, by matching them by key columns.

Upsert Destination supports INSERT, UPDATE, and DELETE operations, so it is similar to SQL Server's MERGE command, except it can be used directly in SSIS package.

From the SSIS Toolbox drag-and-drop Upsert Destination component onto the Data Flow designer background.
Connect your SSIS source component to Upsert Destination.
Double-click on Upsert Destination component to open configuration window.
Start by selecting the Action from the list.
Next, select the desired target connection or create one by clicking <New [provider] Connection> menu item from the Target Connection dropdown.
Then select a table from the Target Table list or click New button to create a new table based on the source columns.
Continue by checking Insert and Update options according to your scenario (e.g. if Update option is unchecked, no updates will be made).
Finally, click Map All button to map all columns and then select the Key columns to match the columns on:
Click OK to save the configuration.
Run the package and Gmail data will be merged with the target table in SQL Server, PostgreSQL, or Redshift:
Done!

Deploy and schedule SSIS package

After you are done creating SSIS package, most likely, you want to deploy it to SQL Server Catalog and run it periodically. Just follow the instructions in this article:
