3. Steps to configure databridge

3.1. Configuring  Qntrl integration

Before setting up a databridge, you must configure Qntrl under System Integrations in Zoho Creator. This enables secure communication between Creator and your private service.
The super admin can also configure Qntrl under Databridge in Operations.

3.2. Configuring databridge 

1. Navigate to Databridge under Operations.
   
2. Click the required operating system and version (for example, macOS - 64 bit) from the list. The databridge package will be downloaded to your system in the format of a zip file. Follow the steps to install the databridge on the machine that has access to your internal services or databases.

   
   

   Note: The download package will only remain accessible for 15 days. 

3. After the installation is complete, the databridge will be added to the listing page under the Databridge section.
   
   
   
   

   Tip: After installation, verify that the databridge is listed in the databridge section. Ensure that the databridge is active. 

3.3. Installing databridge on a server 

Databridge can be installed using one of two package formats, depending on your operating system and how you prefer to manage the installation:

Note: The installer offers a guided UI flow with prompts. The zip method is suited to scripted or headless deployments and runs through the command line.

During installation, you will be asked for proxy settings, external Postgres settings, and a service user account. The behavior is consistent across operating systems:

• Proxy settings: If your server reaches the internet through a proxy, enter the proxy username, password, host, and port. Otherwise, skip this step or disable the proxy.
• External Postgres settings: If you want Databridge to use an external Postgres database, enter its host, port, username, and password. Otherwise, the bundled Postgres will be used.
• Service user account: The non-root local user account that Databridge will run under. This account should not have administrator privileges and must be created on the server beforehand. If the user does not exist when prompted by the zip installer, you will be given the option to create one with only the permissions required to run the service.

3.3.1. Install on Windows using the zip (admin PowerShell only)  

1. Download the Databridge agent zip from Creator.
   
2. Open an elevated PowerShell window (Run as administrator) and extract the agent zip:
   # Extract the agent zip Expand-Archive -Force Bridge.zip 'C:\Bridge'

      Replace Bridge.zip with the path to the actual downloaded zip. 

3. Run the install script with root permission to start the installation:

# Run the install script cmd.exe /c 'C:\Bridge\bin\bridge.bat install'

4. At the proxy settings prompt, choose one of the following:

• Yes - Configure the proxy by entering the proxy username, password, host, and port.
• No - Disable the proxy.
• Skip - Make no changes to proxy settings.

5. At the postgres settings prompt, choose one of the following:

• Yes - Configure external Postgres by entering the host, port, username, and password.
• No - Disable external Postgres and use bundled Postgres.
• Skip - Make no changes to Postgres settings.

6. At the service user prompt, enter a non-root username on your system. If the username does not exist, the create-user prompt will let you create the user with only the permissions required to run the service.
7. Verify that the Databridge has started successfully.
   

Note: The zip installation on Windows must be run from an elevated PowerShell. A standard PowerShell session will not have the privileges required. 

3.3.2. Install on Linux using the zip  

1. Download the Databridge agent zip from Creator.
   
2. Open the terminal and extract the agent zip:
# Extract the agent zip sudo unzip -d /Bridge Bridge.zip

Replace Bridge.zip with the path to the actual downloaded zip. 

3. Run the install script with root permission to start the installation:

# Run the install script sudo sh /Bridge/bin/bridge.sh install

4. At the proxy settings prompt, choose one of the following:

• Yes - Configure the proxy by entering the proxy username, password, host, and port.
• No - Disable the proxy.
• Skip - Make no changes to proxy settings.

5. At the postgres settings prompt, choose one of the following:

• Yes - Configure external Postgres by entering the host, port, username, and password.
• No - Disable external Postgres and use bundled Postgres.
• Skip - Make no changes to Postgres settings.

6. At the service user prompt, enter a non-root username on your system. If the username does not exist, the create-user prompt will let you create the user with only the permissions required to run the service.
7. Verify that the Databridge has started successfully.

3.3.3. Install on Mac using the zip  

1. Download the Databridge agent zip from Creator.
   
2. Open the terminal and extract the agent zip:
# Extract the agent zip sudo unzip -d /Library/Bridge Bridge.zip

Replace Bridge.zip with the path to the actual downloaded zip. 

3. Run the install script with root permission to start the installation:

# Run the install script sudo sh /Library/Bridge/bin/bridge.sh install

4. At the proxy settings prompt, choose one of:

• Yes - Configure the proxy by entering the proxy username, password, host, and port.
• No - Disable the proxy.
• Skip - Make no changes to proxy settings.

5. At the postgres settings prompt, choose one of:

• Yes - Configure external Postgres by entering the host, port, username, and password.
• No - Disable external Postgres and use bundled Postgres.
• Skip - Make no changes to Postgres settings.

6. At the service user prompt, enter a non-root username on your system. If the username does not exist, the create-user prompt will let you create the user with only the permissions required to run the service.
7. Verify that the Databridge has started successfully.
   

3.4. Post installation of the databridge

1. Navigate to Databridge under Operations in your Creator account. Click and open a required databridge from the list. 
   
2. Click Add Connection, in the databridge details page.
   
3. Choose a connector from the list of privately hosted connectors and create the connection as needed. The connector list will be pre-filtered to display only privately hosted connectors.
   
4. 
   
   In the Add Connection popup, your databridge will be selected automatically. Fill in the remaining details to complete the required configurations and click Create and Authorize. Learn more about creating and authorizing connections
   
   
5. The Link Account popup appears, provide the following details: username, password, host, port, and service name. Click Authorize to complete the connection.
   
6. Enable connection access to your application for the created privately hosted connector under the Microservices section.
   
   

Note: The admin configures the databridge and the associated connection. To grant application access, the admin must navigate to the Microservices section and enable access for the relevant application.

 Note:

1. The databridge must remain active for connections to function. If it is inactive, applications will not be able to access data from internal systems.
2. You can add a maximum of 20 databridge in one account.
3. A maximum of 5 databridges can be actively connected at a time. 
4. Databridge requires outbound internet connectivity from the machine where it is installed. It should be installed on a dedicated server that remains powered on. If the machine sleeps or restarts, all associated workflows will be interrupted.
