When you build a chain, you can use the results—or outputs—from a command with properties of subsequent commands. For example, to perform multiple transformations on a command's comma-separated values (CSV) output as part of a chain, add a subsequent Tabular Transformation command that uses the earlier command's output as as property.
Note: Commands can only use outputs from commands earlier in the chain, including those linked with a Success condition or within a group. To extract a value from a command's output, create a dynamic output.
Output types
Connection commands produce several types of outputs:
| Output type | Example |
|---|---|
| Text | Selected records from a listing file output |
| Integer | The number of records in a query |
| File | Downloaded response from a web service HTTP request |
| Float | The results of a floating point calculation |
| Date | The system timestamp |
| JSON | REST API web services response |
| List | The list of files in a directory |
| Map | A list of pairs and values |
Use a command output as a property of a later command
Note: To convert the format or structure of a command's output for use as another command's property, you can apply a variable transformation.
- In the chain, select the command with the property to use the output, and click Edit .
- Under Command Properties, click Variable for the property.
- Under Select a variable, expand the earlier command, and select which of its outputs to input as the property.
- To transform the output's format or structure for use with the property, such as to extract a value from JSON, click on it in the property's field, and apply a variable transformation.
- Click Save.
Command details output
Each command automatically generates a Command Details output. With this output, you can use details about its command as a variable input with a command later in the chain.
| Output variable | Detail |
| Id | The command's numeric ID |
| Status | The command's status—succeeded or errored
