Handling HTTP responses

Fan-out example

The HTTP query widget lets you "fan-out" queries. For example if you have a REST endpoint that returns a list of items. You can add a second HTTP query to fetch the details of each of those items - this is the fan-out part since we are executing multiple queries now instead of just one.

You can use a template to merge these multiple queries into a single output.

{{#each data}} 
{{this.steps.[0].id}}, {{this.result.name}}, {{this.result.bytes}}   
{{/each}}

• #each is how you iterate over a list in Handlebars.
• data is a list of the fanned out items.
