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. Blynk currently have 2 clouds running.
    The old cloud (no longer supported) with host and the new cloud with host
  • 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: – Frankfurt – London – New York – Singapore – Bangalore
The server region could be found in the right bottom corner of the web interface.
