HTTPS API Troubleshooting

All HTTPS API are case-sensitive. Request path and query parameters letter-case shouldn't be changed.
Make sure you're using the correct server. The correct host should be blynk.cloud
In case you're getting the Invalid token. response from the HTTPS API,
and you're sure the device auth token is correct - it could be a GEO DNS issue. 
You can get the Device auth token in Device info.
Due to current GeoDNS settings you need to put server address with suffix manually depending on your region:
https://fra1.blynk.cloud/ – Frankfurt
https://lon1.blynk.cloud/ – London
https://ny3.blynk.cloud/ – New York
https://sgp1.blynk.cloud/ – Singapore
https://blr1.blynk.cloud/ – Bangalore
The server region can be found in the right bottom corner of the web interface.
