Where can I find API keys for MMW? I want to use the data sent to MMW for my sensor to send to an App. How can I do that? Is there an API that is already available?
A Water One Flow (WOF) / WaterML API for scripts or apps to get data out of the MonitorMW database, as documented here: https://monitormywatershed.org/wofpy/
Which one are you trying to use, and how? We need more information in order to help you.
