​
Overview

In Factify, a Document is a container that holds one or more immutable file versions. This design ensures a complete audit trail for legal and compliance purposes.

​
Creating Documents

When you upload a file, Factify creates a Document with Version 1: 
const result = await factify.documents.create({
  payload: await openAsBlob("./contract.pdf"),
  title: "Q4 Sales Agreement",
  description: "Annual sales contract for Q4 2024",  // Optional
});

const document = result.createDocumentResponse?.document;
console.log(`ID: ${document.id}`);
console.log(`Title: ${document.title}`);
console.log(`Current version: ${document.currentVersion?.id}`);

​
Immutability & Versioning

Files in Factify are immutable - you cannot modify or overwrite them. Instead, create a new version: 
// Upload a new version
const result = await factify.versions.create({
  documentId: "doc_01h2xcejqtf2nbrexx3vqjhp41",
  body: {
    payload: await openAsBlob("./contract-v2.pdf"),
    description: "Updated payment terms in section 4.2"  // Optional
  }
});

console.log(`New version ID: ${result.createDocumentVersionResponse?.version?.id}`);

​
Why Immutability?

BenefitDescription
Audit TrailEvery change is recorded with timestamp and metadata
Legal ComplianceOriginal documents are preserved for legal proceedings
RollbackAccess any previous version at any time
Non-repudiationProve what was signed and when

​
Retrieving Documents

​
Get a Single Document

const result = await factify.documents.get({
  documentId: "doc_01h2xcejqtf2nbrexx3vqjhp41"
});

const doc = result.getDocumentResponse?.document;
console.log(doc?.title);
console.log(doc?.currentVersion?.id);
console.log(doc?.createdAt);

​
List All Documents

// Auto-pagination
for await (const page of await factify.documents.list({})) {
  for (const doc of page.listDocumentsResponse?.items ?? []) {
    console.log(`${doc.id}: ${doc.title}`);
  }
}

​
Version History

​
List All Versions

// Auto-pagination
for await (const page of await factify.versions.list({
  documentId: "doc_01h2xcejqtf2nbrexx3vqjhp41"
})) {
  for (const v of page.listVersionsResponse?.items ?? []) {
    console.log(`${v.id} - ${v.createdAt}`);
    if (v.description) {
      console.log(`  Change: ${v.description}`);
    }
  }
}

​
Get a Specific Version

const result = await factify.versions.get({
  versionId: "ver_01h2abcd1234efgh5678jkmnpt"
});

const version = result.getVersionResponse?.version;
console.log(version?.createdAt);
console.log(version?.documentId);

​
Document Metadata

Update document title and description without creating a new version: 
await factify.documents.update({
  documentId: "doc_01h2xcejqtf2nbrexx3vqjhp41",
  body: {
    title: "Q4 Sales Agreement (Final)",
    description: "Approved by legal team"
  }
});
