Learn about the tools available, the redaction process, and the various redaction options provided. Optimize your document redaction ## Overview Apryse WebViewer offers a complete toolset to redact your documents in Appian. You can open files from Appian, externally hosted documents on the web, or from your local machine. Once you have completed redacting a document, you may save it back to Appian, download it, or send it out. ## Pre-requisites You can turn on redaction by setting the `enableRedaction` parameter to `true`. Note that setting the `fullAPI` parameter to `true` is required on older versions of WebViewer to make the functionality work, in newer version (3.1.1+) this is enabled automatically. ## How does redaction work in Appian? Redacting a document will remove the visual information on the document as well as any underlying metadata or text string/data embedded into your document. Once redaction is completed and the document is saved, you are unable to undo this process according to ISO standard. Therefore, redactions are not applied immediately. WebViewer first places a redaction mark onto the document whenever you place redactions. This is a red rectangle that highlights the area to be redacted (marked for redaction). You may hover over this area with your mouse to get a preview for the redaction itself. Once you apply the redaction, the area is blacked out and the information is removed from the document. Do not forget to save the file to complete the process. ## Redaction Tools You have a multitude of redaction tools that accomodate multiple workflows using the viewer UI. * Text hightlighting redaction tool * Redaction area tool * Redact pages tool * Redaction panel search tool ## Redact by highlighting text Use the text highlight tool and click on the redaction button to create a redaction mark. You can also do this from the `Redact` tool ribbon by selecting the redaction tool and highlighting text. ## Redact by adding a redaction area Go to the `Redact` tool ribbon and select the redaction tool. You can either highlight text with this tool or draw a rectangle/box to redact an entire area by drawing your redaction mark and applying the redaction. ## Redact pages Go to the `Redact` tool ribbon and select the `Redact Pages` tool. Select a page, multiple pages, or pass page ranges to remove entire pages from a document. The tool places redaction marks on your selected pages, then redacts the entire pages when page redaction marks are applied. ## Redact with search by keyword You can open the redaction panel from the `Redact` tool ribbon. On the top right of the panel you can search for keywords, each search result is selectable. This allows you to place redaction marks in bulk to allow for faster processing. ## Redact with search by patterns (regular expressions) You can use the search bar on the redaction panel to search for patterns within your document. The following patterns are available: * Phone * Email * Credit Card You can select them from the search results and add multiple redaction marks this way to reduce manual steps required for redaction. ## Redaction workflow Note that you can save your redaction marks before applying them. This enables a review workflow where multiple users can come in and work on the same document. An example could look like so: * User A processes a document by placing redaction marks using the tools listed above * Once all marks have been placed, User A can save the marks as XFDF and ask a Reviewer, User B, to take a look at the processed documents * User B, the reviewer, can place comments on each redaction, they can ask for changes, or add their own additional marks or remove marks where necessary. * The comment panel allows users to approve/decline changes. This allows for interactions between multiple users, which allows for change requests, approval workflows and more. Users can also discuss using the comment threads, reply to comments, and come to a final decision on how the redacted document should look like. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.apryse.com/appian/redaction/redaction.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
