Just like you describe it.

Step 5: How did you make this web API call on UI? Like on linkfield -> safelink -> URL address of web API?

Agree, I have a process running to clear the documents overnight 🙂

This does not work for me either, because Appian does not support it. Did you consider the solution Kumar Agniwesh mentioned below?

Stefan Helzle Could you please help me on the above questions and let me know how to call a integration with modified usage inside Web API because it didn't work for me

If you implement this, make sure to also create a housekeeping process to remove all the temporarily downloaded documents.

Hi Stefan,

My integration is storing document in destination folder and getting document as a result body. As its usage is Modifies data, I can use it in saveInto or Web API. May I know how to use this integration in Web API ?

I tried calling this integration in Web API and used onSuccess parameters using a!save(local!doc,fv!result.body). But it didn't work. Can you please guide me.

/* developer.mozilla.org/.../Redirections */
/* In HTTP, redirection is triggered by a server sending a special redirect response to a request.
Redirect responses have status codes that start with 3, and a Location header holding the URL to redirect to.
When browsers receive a redirect, they immediately load the new URL provided in the Location header.
Besides the small performance hit of an additional round-trip, users rarely notice the redirection.*/

Step1 : Create a process model to download and store the document in a folder.

Step 2 Create a Post webApi to trigger this process model and this webApi should return the documentId of the downloaded document

Step 3 Create a integration object to trigger this webApi and this should be just returning the documentId again

Step 4 Create a get webApi. In this webApi call the integration object and in response use

a!httpResponse(
statusCode: 307,
headers: {
a!httpHeader(name: "Location", value: local!redirect)
}
)

where local!redirect : document(documentID,"url").

Step 5 : Call this webApi as a link in your interface.

You cannot do it in single click but you can have 2 links

1. Fetch Document - Link to call the integration and bring the documents inside appian using dynamic link

2. Click to Download - Link to download the document using document download link

Agreed with Stefan - this sort of thing really requires a 2-click approach to maintain code cleanliness, maintainability, flexibility, etc.

There is no solution I would want to recommend to make this work.
