How To Redirect Url Restapi to salesforce

Question

I am creating a rest Service and its integrated with external system and sending data to external system through lightning component and its working fine while sending the data from Salesforce. while sending data to external system, it will redirect to external system.

In the same way, I need to get the data from external system to Salesforce through hook page. While sending data from external system, it needs to redirect to salesforce page where I was tried to send data from salesforce.

My apex rest service

@RestResource(urlmapping='/test/test/HookPage.aspx/*')
global without sharing class test{


    @HttpPost
    global static String doPost()
    {

        RestRequest req=RestContext.request;
        RestResponse res=RestContext.response;
        Blob body = req.requestBody;

        Map<String,String> params = RestContext.request.params;


        return null ;

    }



}

this my hook page but i want to redirect to salesforce record detail page

please anybody help on this

Answer 1

You are interpreting this incorrectly. APIs are not built for the use case (redirecting to a resource) that you are trying to solve. APIs are web services where they receive a request and return a response and it's up to the caller of the API as what they want to do further with the response.

If I understand this correctly you want to invoke a REST API exposed from Salesforce and that the caller should be navigated to a particular record page. This is not the correct implementation approach. You cannot redirect to a page from your service. Let's say even if you were able to redirect to a page from your service, the caller of the service would never know that because they will only receive a response back from the service.

Your implementation approach here should be to provide a response back to the caller with the absolute url of the record page as a response, and then let the caller decide if they want to redirect it to the resource or not.

I faced the same issue wherein the response, I need to direct to a different page. I used 301 redirection functionality of the browser. The following code will force the browser to redirect to a different page.

@RestResource(urlMapping='/myRestURL')
global class MyRestService {
@HttpGet
global static String doGet() {
    String paramValue = RestContext.request.params.get('param1');
    // Do something
   RestContext.response.statusCode = 301;
   RestContext.response.addHeader('Location','https://www.my-redirect.com/page1');
   RestContext.response.addHeader('http-equiv','refresh');
   return null;
}
}
