Abstract: A method, apparatus, and system for managing data in disparate platforms through an API are described. In response to receiving selection and activation of a connector platform, e.g., heterogenous connector platform, via a computer interface, the connector platform prompts for selection of at least first and second disparate platforms, with which the connector platform is to be authenticated. After authentication, the connector platform generates a unique gateway account key for the connector platform to access data associated with a first account on the first platform and a second account on the second platform, the first and second accounts being associated with the same user, and the connector platform creates a persistent connection between the first and second platforms employing a proactive monitoring process enabling fast, consistent, and reliable access to data associated with the first account on the first platform from the second platform via the connector platform.
