1. A computing device, comprising: one or more processors; a receiver configured to receive a customization file, wherein the customization file includes customized content for customizing a communication interface overlay; and a non-transitory machine-readable storage medium containing instructions which when executed on the one or more data processors, cause the one or more processors to perform operations including: accessing native application code; executing the native application code to run a native application; accessing a compiled set of code, wherein the compiled set of code is separate from the native application code, and wherein the compiled set of code is accessible by the native application code; executing the compiled set of code, wherein a default file of the compiled set of code provides a native communication interface overlay, wherein the native communication interface overlay is overlaid over a graphical interface of the native application upon execution of the compiled set of code, and wherein the native communication interface overlay facilitates communication with a resource of a third-party; and executing the received customization file, wherein executing the received customization file customizes the compiled set of code, and wherein the customized compiled set of code customizes the native communication interface overlay to provide a customized communication interface overlay.
