Long File in Appian

External Portal to Appian: Use a cloud storage service like AWS S3 or Azure Blob Storage to store files larger than 75 MB. Then, have Appian retrieve the file from the cloud storage and send it to SharePoint.
Appian Interface to SharePoint: Again, use a cloud storage service for files larger than 1 GB. Users upload files to the cloud storage via Appian, and then Appian transfers the file to SharePoint through a web service.

Let me know if that works for you?

For scenario 1, the idea we have is as shown in the image.

We have users who are not part of the company and therefore do not have a user in the active directory and cannot connect to the client's VPN. This means that they do not have an Appian user, but we need them to agree to leave us documentation that is over 1 GB in size. For this we have thought of making a customised portal in Angular, so that these users can access from the internet to initiate the request and leave us the documentation. The communication between the angular portal and appian is done through the WSO2 api manager. The challenge is to get the documentation to Appian and then upload it to sharepoint which is the document manager used by the company, but the appian apis do not allow documents larger than 75 MB, so when they call us from the front end to send us the file, we get an error 413 payload too large.

For scenario 2, I show an image with our idea

The problem we have is that appian does not allow to attach in an interface a file bigger than 1GB, so the applications we want to develop where an appian user needs to attach these large files from an interface, are not being able to be done.

Any ideas ?

Did you take a look at this plugin which allows you to upload files up to 15GB directly into Sharepoint (bypassing Appian)?

 SharePoint Direct Upload  

Hello ,

This could be an option for scenario 2, let's try it.

For scenario 1 I still don't see a valid option, because the appian api limits the size of the files you receive, therefore, the file from angular to appian would never arrive.

For scenario 1, why can't you upload the files to Sharepoint via Angular and then send the Sharepoint file IDs in your Appian API request?

As an aside - do you happen to know whether the linked Sharepoint tool and Connected System require Sharepoint Online like the Appian OOB version does?  My company has been asking me how we'll integrate sharepoint but we don't have a compatible cloud version.

We currently integrate with sharepoint by making use of the REST services exposed by the sharepoint API. We do not use the connected system. In our case it is sharepoint online.
