Hi There,
I am quite new to ThingSpeak and I am trying to get some data into fields using http messages. It seems to work fine on field 1 of my channel, but the other fields won't updat (anymore). Any suggestions why this could happen and how I can check whether my messages have been sent/received?

If there is a 200, the data should be accpeted.
Have a look at the recent data to see what is being written to the channel.
Use the read data API see the last few entries.
Use a format like this
https://api.thingspeak.com/channels/YOUR_CHANNEL_ID/feeds.json?results=50&api_key=YOUR_READ_API_KEY
Can you show the part of your code where you write to multiple fields?
Do you use this format?:
https://api.thingspeak.com/update?api_key=WRITE_API_KEY&field1=0&field2=43 etc.

Hi Christopher,
Thanks for your reply!
https://api.thingspeak.com/update?api_key=WRITE_API_KEY&field1=0&field2=43, this will defenitely help me to improve my code. I was sending each field individually, so within 15 sec interval (thanks Vinod!).
I noticed that when I send th field-update individually with a larger interval, it works! With your reply I can now update all fields in one update!
Kind regards,
Wouter Mets

What is likely happening is that the fields are being updated inidvidually, and faster than once per 15s. What you really want to do is update all feeds on the channel at the same time. Definitely use the ThingSpeak library and take a look at this example as a reference.
