Using google app script I want to post measurements from my home domotics to a thingspeak channel. The chart has several charts.
I am using the following code
POST https://api.thingspeak.com/update.json
api_key=XXXXXXXXXXXXXXXX
field1=73
and after a few seconds
POST https://api.thingspeak.com/update.json
api_key=XXXXXXXXXXXXXXXX
field2=100.
In the channel it only updates the chart for field1. When I introduce a sleep of 15 seconds between the 2 posts, it will show both charts (field1 and field2). It seems not possible to send both posts with short intermediant times to update the both charts. Or should I use another way to achieve almost simultaneous updates of multiple charts ?

The free ThingSpeak account tier has an update rate limit of 15 seconds.
You can send both field values in one update.
field1=73&field2=100
