Actually I've implmented ios in-app purchase & upon success, I receive json response. The json response contains PurchaseToken, which is basically a base64 encoded javascript string.

I deserialize the above object & decode the base64 purchaseToken, but the decoded string is javascript string rather then json (look at the = & ;).

I'm facing this issue with deserializing of the javascript string into a C# object. Any proper way to handle this deserialization? Newtonsoft.Json is not able to handle it & I have looked its docs again & again to find any suitable methods but no success.
Is there any way other then to replace characters & make its json like?
Any help would be highly appreciated.
As others already mentioned, it's not JSON. But based on the example you provided you should be able to transform it to a readable JSON. It's not the most pretty solution, but it seems to work. It have some draw-backs:
It will only work when " = " is the separator.
It will only work when each field is separated by ; followed by line-break (windows-style).
private string MakeReadableJson(string base64Input)
{
var data = System.Convert.FromBase64String(base64Input);
string readableString = Encoding.UTF8.GetString(data);
var json = readableString.Replace("\" = \"", "\":\"").Replace(";\n", ",");
return json;
}
I use System.Text.JsonSerializer. Use it like so:
string json = @"{
""Id"": ""1000000872920320"",
""TransactionDateUtc"": ""2021-09-06T14:42:17Z"",
""ProductId"": ""1"",
