Write a Simple Go Application to work with Monday.com Data on Linux

Use CData ODBC drivers and unixODBC to create a simple Go app with live connectivity to Monday.com data.

Go is an open source programming language that enables you to easily build software on Linux/UNIX machines. When Go is paired with the ODBC Driver for Monday.com and unixODBC you are able write applications with connectivity to live Monday.com data. This article will walk you through the process of installing the ODBC Driver for Monday.com, configuring a connection using the unixODBC Driver Manager, and creating a simple Go application to work with Monday.com data.

Using the CData ODBC Drivers on a Unix/Linux Machine

The CData ODBC Drivers are supported in various Red Hat-based and Debian-based systems, including Ubuntu, Debian, RHEL, CentOS, and Fedora. There are also several libraries and packages that are required, many of which may be installed by default, depending on your system. For more information on the supported versions of Linux operating systems and the required libraries, please refer to the "Getting Started" section in help documentation (installed and found online).

Installing the Driver Manager

Before installing the driver, you need to be sure that your system has a driver manager. For this article, you will use unixODBC, a free and open source ODBC driver manager that is widely supported.

For Debian-based systems like Ubuntu, you can install unixODBC with the APT package manager:


apt-get install unixodbc unixodbc-dev

For systems based on Red Hat Linux, you can install unixODBC with yum or dnf:


yum install unixODBC unixODBC-devel

The unixODBC driver manager reads information about drivers from an odbcinst.ini file and about data sources from an odbc.ini file. You can determine the location of the configuration files on your system by entering the following command into a terminal:


odbcinst -j

NOTE: You may need to install odbcinst. Use the following command in a terminal:


apt install odbcinst

The output of the command will display the locations of the configuration files for ODBC data sources and registered ODBC drivers. User data sources can only be accessed by the user account whose home folder the odbc.ini is located in. System data sources can be accessed by all users. Below is an example of the output of this command:


DRIVERS............: /etc/odbcinst.ini
SYSTEM DATA SOURCES: /etc/odbc.ini
FILE DATA SOURCES..: /etc/ODBCDataSources
USER DATA SOURCES..: /home/myuser/.odbc.ini
SQLULEN Size.......: 8
SQLLEN Size........: 8
SQLSETPOSIROW Size.: 8

Installing the Driver

You can download the driver in standard package formats: the Debian .deb package format or the .rpm file format. Once you have downloaded the file, you can install the driver from the terminal.

The driver installer registers the driver with unixODBC and creates a system DSN, which can be used later in any tools or applications that support ODBC connectivity.

For Debian-based systems like Ubuntu, run the following command with sudo or as root: dpkg -i /path/to/package.deb

For systems that support .rpms, run the following command with sudo or as root: rpm -i /path/to/package.rpm

Once the driver is installed, you can list the registered drivers and defined data sources using the unixODBC driver manager:

List the Registered Driver(s)


odbcinst -q -d
CData ODBC Driver for Monday.com
...

List the Defined Data Source(s)


odbcinst -q -s
CData Monday Source
...

To use the CData ODBC Driver for Monday.com with unixODBC, you need to ensure that the driver is configured to use UTF-16. To do so, edit the INI file for the driver (cdata.odbc.monday.ini), which can be found in the lib folder in the installation location (typically /opt/cdata/cdata-odbc-driver-for-monday), as follows:

cdata.odbc.monday.ini


...

[Driver]
DriverManagerEncoding = UTF-16

Modifying the DSN

When the driver is installed, a system DSN should be predefined. You can modify the DSN by editing the system data sources file (/etc/odbc.ini) and defining the required connection properties. Additionally, you can create user-specific DSNs that will not require root access to modify in $HOME/.odbc.ini.

You can connect to Monday.com using either API Token authentication or OAuth authentication.

Connecting with an API Token

Connect to Monday.com by specifying the APIToken. Set the AuthScheme to Token and obtain the APIToken as follows:

API tokens for admin users
1. Log in to your Monday.com account and click on your avatar in the bottom left corner.
2. Select Admin.
3. Select "API" on the left side of the Admin page.
4. Click the "Copy" button to copy the user's API token.
API tokens for non-admin users
1. Click on your profile picture in the bottom left of your screen.
2. Select "Developers"
3. Click "Developer" and then "My Access Tokens" at the top.
4. Select "Show" next to the API token, where you'll be able to copy it.

Connecting with OAuth Authentication

Alternatively, you can establish a connection using OAuth (refer to the OAuth section of the Help documentation).

/etc/odbc.ini or $HOME/.odbc.ini


[CData Monday Source]
Driver = /opt/cdata/cdata-odbc-driver-for-monday/lib/libmondayodbc.x64.so
Description = My Description
APIToken = eyJhbGciOiJIUzI1NiJ9.yJ0aWQiOjE0MTc4NzIxMiwidWlkIjoyNzI3ODM3OSwiaWFkIjoiMjAyMi0wMS0yMFQxMDo0NjoxMy45NDFaIiwicGV

For specific information on using these configuration files, please refer to the help documentation (installed and found online).

Creating a Simple Go App for Monday.com Data

With the Driver Manager installed and the DSN configured, you are ready to create a simple Go application to work with your Monday.com data. To start, install a Go driver for ODBC databases. While there are several options available, this article will use the odbc driver found at https://github.com/alexbrainman/odbc.

Installing ODBC on Linux

There are a series of steps required to install the ODBC driver for Go.

Create the $HOME/golang/go path (if it does not exist) by entering the following commands in a terminal: mkdir /root/golang mkdir /root/golang/go
Define the GOPATH environment variable: export GOPATH=$HOME/golang/go
Create a module inside the new Go directory: cd $GOPATH go mod init myproject
Install the Go driver for ODBC databases:
go get http://github.com/alexbrainman/odbc

Now you are ready to create and execute a simple Go application.

Sample Go Application

The sample application issues a simple SQL SELECT query for Monday.com data and displays the results. Create the directory $GOPATH/src/cdata-odbc-monday and create a new Go source file, copying the source code from below.

cdata-odbc-monday.go


package main

import (
  _ "github.com/alexbrainman/odbc"
  "database/sql"
  "log"
  "fmt"
)

func main() {
  db, err := sql.Open("odbc",
    "DSN=CData Monday Source")
  if err != nil {
    log.Fatal(err)
  }

  var (
    id string
    duedate string
  )

  rows, err := db.Query("SELECT Id, DueDate FROM Invoices WHERE Status = ?", "SENT")
  if err != nil {
    log.Fatal(err)
  }
  defer rows.Close()
  for rows.Next() {
    err := rows.Scan(&id, &duedate)
    if err != nil {
      log.Fatal(err)
    }
    fmt.Println(id, duedate)
  }
  err = rows.Err()
  if err != nil {
    log.Fatal(err)
  }

  defer db.Close()
}

In the terminal, navigate to the Go application directory and build the application:


go build

After the application builds, you will be able to execute the application, displaying your Monday.com data:


./cdata-odbc-monday

At this point, you have a simple Go application for working with Monday.com data. From here, you can easily expand the application, adding deeper read functionality through familiar SQL queries.
