Question

webAPI taking more time for document download

I have a webAPI which will receive the document from external system in binary format, but for file size around 25 MB, the API is taking more than 25 seconds.
Is there any way we can increase the API performance by reducing the time taken by it?

Thanks in advance.

You can't significantly speed up the binary transfer itself in Appian's Web API.
Increase client side timeouts (>30s).
25MB in 25s (~1MB/s) indicates a network/bandwidth issue, not Appian.
The bottleneck is likely network speed or external system performance, not Appian.

To increase the performance of any API, you will have to talk to the people developing that API.

Can you please confirm are they generating the file and then providing you the file? or only providing the Binary file?
