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.
