Development:API

Documentation of the current implementation of the API used between TapTo and TapTo Life. The API is mainly a REST API, but also implements a separate WebSocket API for certain functions that work better in real time (like tracking the current played game).

When this documentation refers to a "system ID" it is talking about the supported systems list used by the MiSTer Extensions project, the various computer and console systems supported by MiSTer. TapTo will eventually fork this list of system definitions, so it can be expanded beyond MiSTer supporter systems. Existing system IDs will remain the same to preserve backward compatibility or kept as aliases.

This API is not finalized. Please don't implement anything using it yet without expecting breaking changes.

REST

The REST API is accessible at http://[IP/hostname]:7497/api/v1 and can be used with any standard HTTP client such as curl, which is used for all examples.

Status

Get the current overall status of various parts of the TapTo service.

GET /status

On success, returns 200 and an object containing the state of various parts of the TapTo service.
