Blynk-Cloud
APIAPI to Control IoT Devices via Blynk IoT Cloud
Overview
The Blynk-Cloud API enables developers to interact with IoT devices connected to the Blynk IoT platform. Key endpoints include pin state manipulation (read/write digital/analog values), device management (list devices, update settings), event retrieval, and user dashboard interactions. Responses are JSON-formatted. Use cases include automating device actions based on external triggers, syncing IoT data with enterprise systems, building custom monitoring dashboards, or integrating Blynk devices with voice assistants like Alexa/Google Home. It supports RESTful interactions and requires authentication via API tokens for secure access.
