public class HttpInvoke
extends TaskStateBase

A Step Functions Task to call a public third-party API.

Example:

         .apiEndpoint(TaskInput.fromText("{% 'issues/' & $states.input.issue.id %}"))
         .method(TaskInput.fromText("GET"))
         // Parse the API call result to object and set to the variables
         .assign(Map.of(
                 "hostname", "{% $states.input.hostname %}",
                 "issue", "{% $parse($states.result.ResponseBody) %}"))
         .build());
 HttpInvoke updateLabels = HttpInvoke.jsonata(this, "Update Issue Labels", HttpInvokeJsonataProps.builder()
         .connection(connection)
         .apiRoot("{% 'https://' & $states.input.hostname %}")
         .apiEndpoint(TaskInput.fromText("{% 'issues/' & $states.input.issue.id & 'labels' %}"))
         .method(TaskInput.fromText("POST"))
         .body(TaskInput.fromObject(Map.of(
                 "labels", "{% [$type, $component] %}")))
         .build());
 Pass notMatchTitleTemplate = Pass.jsonata(this, "Not Match Title Template");
 Chain definition = getIssue.next(Choice.jsonata(this, "Match Title Template?").when(Condition.jsonata("{% $contains($issue.title, /(feat)|(fix)|(chore)(w*):.*/) %}"), updateLabels, ChoiceTransitionOptions.builder()

                 "component", "{% $match($states.input.title, /(w*)((.*))/).groups[1] %}"))
         .build()).otherwise(notMatchTitleTemplate));
