Managing Variables for the Workspace and Chains

To set values for inputs that appear repeatedly in multiple chains or commands within a single chain, you can use variables. Rather than input the same value in multiple chains or commands, you can define it as a variable, and manage its value in one location.

• Workspace variables define values that appear across multiple chains.
• Chain variables define values that appear in multiple commands of a chain and may change frequently.
• Dynamic variables define values to set when a chain runs or during the execution of a chain, such as based on an earlier command's output.

Managing Your Workspace's Variables

From your workspace, you can define the variables used by multiple chains.

1

From Wdata Chains, click Workspaces  build and Edit.

2

Under Variables, click Add Variable.

3

To help identify the variable, enter its name and, if necessary, default value.

4

To enable only admins to view the variable's value, select Encrypt.

5

Click Save.

After you add a variable to your workspace, you can edit its name, value, or encryption as necessary. To remove a variable from the workspace, click its Delete.

Managing a Chain's Variables

For values that appear in multiple commands within a chain and change frequently, add them as variables for the chain:

1

In the chain, click Chain Settings.

2

Under Variables  code, click Add  add .

3

Enter a unique name to help identify the variable and its intent.

4

Enter the default value for the variable.

5

To enable only admins to view the variable's value, select Encrypt.

6

Click Save.

To update a variable, click Edit for the chain, and adjust the value under Variables.

To remove a variable you no longer need, click Delete  close .

Managing a Chain's Dynamic Variables

To set values when the chain runs, or to base values on another command's output, add them as dynamic variables for the chain:

1

In the chain, click Chain Settings.

2

Under Dynamic Variables  code, click Add  add.

3

Enter a unique name to help identify the variable and its intent.

4

Enter the initial value for the variable, and click Save.

To remove a variable you no longer need, click Delete close .

Using Variables as Command Inputs

To use variables as text-based inputs for a command:

1

From the chain, select the command to use the variables.

2

In the text-based input to use a variable, click Variable  code, and select the variable.

3

Click Save.

Default Variables

Several variables for data related to chains, commands, and the system's date and time are available out-of-the-box.
