How-to expose API with several output parameters
Question
Reactive
API

Hello all,

I am using OutSystems to expose an API method to get data about surveys and their questions.

I have a method where I pass the survey identifier and I want to get information about the survey (title, description, some dates, etc) and about their questions (question, question description, question type, and question multiple choice options).

This is the method:

And this is the JSON that I hope to achieve:

However, I get an error saying "Method can only have 1 output parameter when the Send In property is set to Body". Also, I understand that my JSON will not miraculously look like that, with the questions inside the survey.

Does anyone know how to achieve this? Thank you very much.

Hi,

I placed here an example, you need to adjust the structure as you need. You need to create a structure that support the questions inside the survey (something like this, you need to adjust the required fields):


Hope this can help.

Hi!

I think that you can apply the same principles that the platform apply to services auto generated:


About the nested point, can you place here a picture or the definition of the structure that you're trying to use?

Thanks!

Hi,


You will need to create a structure. In that structure, you will need to have a Survey Record and a List of Question records:

Then, You will need define an output of the type of that structure:

Then, you will need to append the records from survey and the questions to that output.


Hope this can help.

Hello Ricardo, thank you. I have done that but the JSON doesn't look the way it should, with the questions nested inside the survey.

Questions is of data type surveys_Questions, and Surveys is of data type surveys_Surveys.

Then, I changed my output parameter to the structure:

And I appended them to the structure.

But the JSON is not nested:
