Use Iterators with Commands and Command Groups

To enable a command or command group in a chain to run repeatedly, use an iterator. With an iterator, you can run commands over a static or dynamic list of values—such as an output from an earlier command in the chain—and use the values as a property of the command. 

Note: To convert an output from a relational database or external web service to a JSON array to use with an iterator, use the JSON connector's CSV to JSON command or a JSON variable transformation.

Enable an Iterator for a Command or Command Group

1. In the chain, select the command or group to repeatedly run, and click Edit create.
2. Under Iterations, enable Iterator repeat, and enter the iterations' values:
   
   
   • For a static list, enter the values for each iteration, pressing Enter after each.
   • For a dynamic list, click Variable code, and select the command output to use.
3. Click Save.

Use an Iteration as a Command Property

To input the iteration values as a property in the command or another command in the group:

1. In the chain or group, select the command to use the iteration, and click Edit create.
2. For the property to use the iteration values, click Variable code, and select Command Iteration or Group Iteration under Command Iterator or Group Iterator.
   
3. Click Save.
