Abstract
Systems and methods are directed to enabling a client device to insert customized content from a first server into a webpage received from a second server without using an asynchronous data fetching protocol. The second server determines contextual information related to the client device and prepares a container webpage that includes an image link having one or more parameters based on the contextual information. The client device receives and uses the image link to send, to the first server, an image request with the one or more parameters and a cryptographically verifiable token generated by the second server. The first server uses the token to verify that the second server generated the one or more parameters and generates a customized image using the one or more parameters. The client device receives and renders the customized image within the container webpage without reloading the container webpage.
