How to create a REST API to download attachment?

[Subhashree3]

Hi All,

We have one requirement where we need to create a Rest API which will be used by other external system in order to download the attachment.

I am confused between Scripted Rest API, Rest Message and Rest API explorer as I am new to this. Please let me know in this case which method will be considered and if you can provide any reference to create a REST API to download the attachment, that would be really helpful for me.

Thank You.

Hi Ram,

Since processor is deprecated in servicenow and the alternative suggested is scripted rest api, can you suggest what change i should make in above script to work as rest api as i guess g_response will not work in that case?

 var out = new Packages.java.util.zip.ZipOutputStream(g_response.getOutputStream());
