Context Variables

Map context variables :

• input - User input as stated in the profile

Example № 3map RetrieveMessageStatus {  
  http GET "/chat-api/v2/messages/{input.messageId}/history" {
    response 200 "application/json" {
      map result {
        deliveryStatus = body.history[0].state
      }
    }
  } 
}

Context Variables

Operation context variables :

• args - arguments as passed in the parent’s OperationCall

Example № 6operation CountArray {
  return {
    answer = "This is the count " + args.array.length
  }
}

Condition and iteration

When both Condition and Iteration are specified, the condition is evaluated for every element of the iteration.

Context Variables

OperationCallSlot context variables:

• outcome.data - data as returned by the callee
• outcome.error - error as returned by the callee

Example № 13operation Bar {
  set {
    variable = 42
  }

  call FooWithArgs(text = `My string ${variable}` some = variable + 2 ) {
    return if (!outcome.error) {
      finalAnswer = "The final answer is " + outcome.data.answer
    }

    fail if (outcome.error) {
      finalAnswer = "There was an error " + outcome.error.message
    }
  }
}

Example № 14map RetrieveCustomers {
  // Local variables
  set {
    filterId = null
  }


  // Step 1
  call FindFilter(filterName = "my-superface-map-filter") if(input.since) {
    // conditional block for setting the variables
    set if (!outcome.error) {
      filterId = outcome.data.filterId
    }
  }

  // Step 2
  call CreateFilter(filterId = filterId) if(input.since && !filterId) {
    set if (!outcome.error) {
      filterId = outcome.data.filterId
    }
  }

  // Step 3
  call RetrieveOrganizations(filterId = filterId) {
    map result if (!outcome.error && outcome.data) {
      customers = outcome.data.customers
    }
  }

  // Step 4
  call Cleanup() if(filterId) {
    // ...
  }
}

Example № 15operation Baz {
  array = [1, 2, 3, 4]
  count = 0
  data = []

  call foreach(x of array) Foo(argument = x) if (x % 2) {
    count = count + 1
    data = data.concat(outcome.data)
  }
}

Example № 16operation Baz {
  array = [1, 2, 3, 4]
  data = call foreach(x of array) Foo(argument = x) if (x % 2)
  count = data.length
}
