Is there any way to expose a Appian document as BloB URL to external system API?

Create a web api and select the right template. Do you have any further questions?

Thanks Stefan,

i have created a Web API based on Document download template with default GET as HTTP Method. 

Now sample webapi for one of the document with id like "https://<ourAppianCloudInstance>/suite/webapi/downloadapi/7024"

Can I give this URL as BLOB URL when the external API expecting a BLOBUrl as parameter intheir input payload?

Calling that API will return the binary file as the HTTP body.

Thank you, in some cases we have to send multiple files in a single Web API call. Please guide us to handle this case as well.

What do you mean with "send"? I mean, you asked for how to download a file from Appian. That's the opposite of "sending".

The only way to download multiple files is, by doing multiple calls, or put the files into a ZIP and download that.
