Hello @yiddy,
First of all can you please share your Automation Scripting block code. Then peoples can see it and give suggestion for optimization.
Also mention API documentation link that where do you post the data.
Mostly single reauest is works fine with that 30 second threshhold. So based on your request/response data I can give you more idea about it.
Another external option is use Make.com automation where it accept data as we webhook. You need to send data from airtable to Make using that same script then it will handle everything. Using of this method you don't need to care anything just need to send data to Make.
I hope this helps to you.
👍
