 Hi @sdetweil 
 It would seem that to have a valid API Key you need to “Enabling billing on Google Cloud Platform …”.
 To receive the API Key, you need to enter a valid credit card number.Did you do this too? 
 Do you agree?Thanks. 
- 
 @Egnos yes. The apis are not free, altho our usage is typically below the 1st tier charge level 
- 
 @sdetweil so you also entered your credit card? 
 How many accesses does this module make per day?
- 
 @Egnos yes, credit card. I don’t know number of accesses. U can control that I think. Not my module. Readme says default is once every 15 minutes updateInterval So, 96 times per day

 Hi, i just a question about MMM-GoogleMapsTraffic and google console plateform. My period of free account is finished so my apy key is not usable. If i understand the only solution to obtain a valid api key with google maps is to pay ? An other question is if the result is the same with api key for MMM-Google photos and MMM- MK2 ? Thanks for next answers
