How to make parallel (simultaneous) API calls?

[Smith Johnson]

Hello,

I have a use case where I want to make 4 api calls to the same endpoint (with different query parameter each time). Now, what I do is it to make the 4 calls sequentially in a script include. However, this causes huge delays.

Is there a way in server-side SN to make 4 API calls in parallel?

Any ideas are highly welcomed.

Smith.

HI @Smith Johnson ,

You can create an event and perform the actual processing in the Script Action associated with the event. And wait for all the events to be processed.

Mark my answer correct & Helpful, if Applicable.

Thanks,

Hi Sandeep,

thanks for your idea.

I have a concern.

Should I trigger 4 different events from my script include? If yes, then I will have four different script actions? And then, can the script actions return the response of each call back to my script include??? I want only to continue the rest code of the script include if I have the responses of all API Calls.

Hi @Smith Johnson ,

Were you able to figure out the solution for this?
