Error:Request failed: bad request (400) afnetworking batch in swift

Question

I am trying to get batch to push notifications to my app through swift. I am trying to convert the curl command in this site below through swift, so that i can request a push notification from batch through swift:

https://batch.com/doc/api/transactional.html

Here is my attempt in swift:

let manager = AFHTTPRequestOperationManager()
            manager.requestSerializer.setValue("REST API KEY", forHTTPHeaderField: "X-Authorization")
            manager.requestSerializer.setValue("application/json", forHTTPHeaderField: "Content-Type")

        var param: [String:AnyObject] = [
                "group_id": "welcome",
                "recipients": [
                    "tokens": ["USER_TOKEN"]
                ],
                "message": [
                    "title": "Hello",
                    "body": "Hi!"
                ],
                "custom_payload": "{\"tag\":\"wake up push\", \"landing_screen\":\"greeting\"}",
                "sandbox":true
        ]

        manager.POST( "https://api.batch.com/1.0/"API KEY"/transactional/send",
        parameters: param,
        success: { (operation: AFHTTPRequestOperation!,responseObject: AnyObject!) in
        print("Push Notification Successfully sent!")
        print("JSON:" + responseObject.description)
        },
        failure: { (operation: AFHTTPRequestOperation!,error: NSError!) in
        print("Error:" + error.localizedDescription)
        })

I kept on getting error:

Error:Request failed: bad request (400)

Any Ideas/Directions will be welcomed Thanks!

You should better use this Swift client for the Batch.com Transactional API.

All HTTP response error codes for this API are explained in the documentation but a 400 Bad request error shouldn't happening, it must be a temporary error on Batch.com's end.

I suppose you have replaced REST API KEY, USER_TOKEN and API KEY with valid values?
