Services 3.0 Json string reveived with underscores I am using D7 services 3.0 and im sending data from an app. I use the json.stringify function before sending the data to my endpoint. However some characters are being replaced by underscores. For instance test@gmail.com becomes test@gmail_com. Any ideas?

When PHP receives POST/GET it replaces dots in keys with an underscore. I would look at the app receiving the data and see if you can work around it there.
