Frontend callback feature is released on May 14, 2022.

Introduction

Our SDK provides a callback after closing or submitting the survey by the user. In the below code, you will see how to implement a 1flow survey callback using Observer.

Set-up Observer:

SWIFT

swift
NotificationCenter.default.addObserver(self, selector: #selector(surveyDidFinish(notification:)), name: SurveyFinishNotification, object: nil)

Objective-C

objective-c
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(surveyDidFinish:) name:@"survey_finished" object:nil];

Read user info to get submitted survey detail:

SWIFT

swift
@objc func surveyDidFinish(notification: Notification) {
    if let userInfo = notification.userInfo {
         print("Notification userInfo: \(userInfo)")
    }
}

Objective-C

objective-c
- (void)surveyDidFinish:(NSNotification *)notification {
    NSDictionary *userInfo = notification.userInfo;
    NSLog(@"Notification userInfo: %@", userInfo);
}

        },
        {
          "answer_value": "Other",
          "other_value": "Checkbox Other"
        }
      ]
    },
    {
