Hi Srikanth, I believe the callback key is the only way to pass credentials in callback notification. But you can always combine your parameters(auth param and x-api key) into one string and encrypt the string and decrypt them from the request header. Hope this could help you! Duo

Hi Srikanth, As we discussed above, the only parameter OneSpan Sign can pass to you through callback notification is the "Authorization" attribute in the Request Headers. Here's the Spring MVC code I tested:

	
       @PostMapping("/callback")
	public String video(@RequestBody String body, @RequestHeader HttpHeaders headers) {
		System.out.println("receive a request...");
		System.out.println(headers.get("Authorization"));
		System.out.println(body.toString());
		
		return "index";
	}

This the what printed in the console:

receive a request...
[Basic callbackKey]
{"@class":"com.silanis.esl.packages.event.ESLProcessEvent","name":"PACKAGE_CREATE","sessionUser":"18EZDL44xgsX","packageId":"MCZ48z0FyrO3NYLgqBOXvMNmYGY=","message":null,"documentId":null,"createdDate":"2018-08-29T14:44:16.945Z"}

So I think it's impossible for you to set two parameters in Request Headers and verify the request directly. But you can combine and pass these two values in "Authorization". Please let us know if this works for you. Duo

Hi Danish, Please refer to the replies in your latest thread. Duo

Hi test_sn, Can you double check with your api key and the environment URL, and which environment are you currently in? Are you using REST api or SDK? Besides that, are you using a proxy connecting to OneSpan Sign? Can you try hitting GET /api/sysinfoor eslClient.getSystemService().getApplicationVersion() in SDK to test your connection with OneSpan Sign? Duo

Hi Gamal, Currently, there's still no way to set a handover url or trigger front-end event. As a workaround, you can #1. disable the "SENT TO SIGN" button #2. embedded designer view into a modal, close it when ready to send or #2. embedded designer view into an iFrame, and have another button with handover url in the rest of the html page. This is how other integrator does with Designer View for now. Duo
