Okay, I've tried a few different ways to post to any channel I've created but haven't had any success. I'm going to throw up a channel for anyone else to try and post to just in case I'm doing something way wrong. Originally I tried to post temerature data from a nodemcu/esp8266 and when that didn't work I set up another channel and used Postman to try and send data. That didn't work either. I can do GET requests to see channel info but I can't get any data to post to the channel. Any help is appreciated.
I made a test channel and made it public just to see if anyone can post to it. It's just a single field and on a free account so don't go crazy.
write: KYY2MERT251RV2OM
read: S325VXRJTWDUZQRI
Postman:
GET https://api.thingspeak.com/channels.json?api_key=XXXXXXXXXXXXXXXXX (Not sharing my account key but JSON results show the channel)
[
{
"id": 897564,
"name": "testCount",
"description": "",
"latitude": "0.0",
"longitude": "0.0",
"created_at": "2019-10-29T23:06:45Z",
"elevation": "",
"last_entry_id": null,
"public_flag": true,
"url": "",
"ranking": 30,
"metadata": "",
"license_id": 0,
"github_url": null,
"tags": [],
"api_keys": [
{
"api_key": "KYY2MERT251RV2OM",
"write_flag": true
},
{
"api_key": "S325VXRJTWDUZQRI",
"write_flag": false
}
]
}
]
Tried both the GET and POSTMAN tutorials here with no luck: https://www.mathworks.com/help/thingspeak/writedata.html
Any attempt to use a GET or POST to update the channel (field1) results in a return of '0' or 401, which I think means that Thingspeak is not recognizing my write API key. I've had the same problem on multiple channels.
Much appreciate any help. Please let me know if you need more information.

Have you had this account for several years? If so you probably would have recieved am email with instructions about how to renew sometime over the summer. We can look into the license issue, it should be possible to renew your free license. I would reccomend changing your API keys for security reasons. Dont worry about posting new screen shots, these are more than enough.
Can you tell us more about your project? We are always looking for interesting applications.

Thanks for confirming and marking the answer (Vinod actually did all the work to fix it though). This may be our first lizzard cage monitor! Can we get a picture of the lizzard, or at least his/her/their name?

That would be the format to try if those are truly the correct API keys for the channel. Be sure to check your API keys.
And definitely check out the library suggested by Vinod.

Jacob,
It appears an email from July 2019 requiring the account to be linked to a MathWorks Account before the end of August 2019 was ignored. Thereby making your old account inactive and license expired. Now that you have linked your ThingSpeak account to a MathWorks Account, we've re-enabled the account.
Let me know if you're still having trouble posting to your channel.

Hi, I also ignored e-mail from thingpseak, and now I can't post to my channel
Now linking with MathWorks account didn't help ;-(
Vinod, can you fix this for me ?
My channel is: 78900 (nice number to remember)
Thanks!

Hello Christopher,
I'm also facing the same issue.
I have an account since 2017, havent been using it for a while.
When i created a new channel today and tried to push data to thingspeak i'm getting HTTP error -401.
I have linked my thingspeak with matlab account
Channel ID: 957975
I tried https://api.thingspeak.com/update?api_key=xxxxxxxxxxxxxxxx&field1=1230 and gets result as 0.
Thanks

@Ashin: It appears you also missed the window to link your accounts? We had to manually reset the account. Please let me know if you are still not able to update your channel.
