SendToHTTP,api.thingspeak.com

[Gaitss]

Hello,
I searched but did not find so I allow myself this post.
I try to retrieve values ​​on Thingspeak with this code: SendToHTTP,api.thingspeak.com,80,/channels/123456/fields/2/last.csv
Response : EVENT: http#api.thingspeak.com=200
So it works but the rest of the code
On ThinkspeakReply Do
LogEntry,'%eventvalue2%'
does not provide a response...
What is the error please?
Thank you
Gaitss

What exact build are you using? As the LIMIT_BUILD_SIZE builds (most ESP8266 builds have that set), exclude this feature.
Simplest is to use an ESP32 build, that all have this Thingspeak feature included,
second alternative is to use an ESP8266 4M1M NORMAL build, that doesn't have LIMIT_BUILD_SIZE set, (IIRC)
third alternative is to create a Custom ESP8266 build, using Custom.h as documented here and make sure it has #define FEATURE_THINGSPEAK_EVENT 1
