title: Document Vault API
description: "The Document Vault API lets you create a secure, shareable container of documents — a **Document Vault** — and manage its contents programmatically. It lets you exchange the right paperwork with the other side of the transaction without rekeying or trading email attachments.\n\nUsed with **Contract Pack Vault** for conveyancing firms (see [Contract Pack Vault](#section/Contract-Pack-Vault)).\n\n# Overview\n\nUse this API from your case management system to assemble a contract pack, then open **Contract Pack Vault** to check it and share it with the buyer's conveyancer. The API builds and maintains the vault; reviewing and sharing happen in the web app.\n\n1. **Create a Document Vault** — supply the property address and as much detail as you have. You get back a vault `id`; use it in every follow-up call and to open the vault in the web app. Optionally set a `reference` (your case reference), which must be unique within your account.\n2. **Add documents**, one per call. Each file is virus-scanned and analysed in the background. Its `status` is `Pending` while that runs, then `Available` or `Quarantined` if it failed the virus scan.\n3. **Keep details current** — update the reference, property, or recipient organisation, and add or remove recipients. Setting up recipients is not the same as sharing; you share the vault from the web app.\n4. **Check progress** with `Get Document Vault` or `Get Activities` for the audit history.\n5. **Open the web app** to review the analysis and share the vault. See [Contract Pack Vault](#section/Contract-Pack-Vault).\n\n# Getting started\n\nREST API over HTTPS with JSON responses; file uploads use `multipart/form-data`.\n\n**UAT** (building and testing): `https://uat-api.landmarkcloudservices.com/document-vaults`\n\n**Auth:** `https://lmkmaster-uat.eu.auth0.com/oauth/token`\n\n**Production** (live integration only; vaults are real and may incur a cost): `https://api.landmarkcloudservices.com/document-vaults`\n\n**Auth:** `https://lmkmaster.eu.auth0.com/oauth/token`\n\n## Authentication\n\nOAuth 2.0 client credentials. Each conveyancing firm is onboarded individually with Landmark and receives its own client ID, secret, and `Account-Id` (sent as a header on every request). Credentials are issued separately for **UAT** (building and testing; not charged) and **Production** (live integration only). If you integrate via a case management system, that system typically holds the firm's credentials on its behalf.\n\nAudience is fixed per environment:\n\n- UAT: `https://uat-api.landmarkcloudservices.com`\n- Production: `https://api.landmarkcloudservices.com`\n\n**1. Get an access token** by POSTing to the auth endpoint for your environment:\n\n```json\n{\n \"client_id\": \"your-client-id\",\n \"client_secret\": \"your-client-secret\",\n \"audience\": \"https://uat-api.landmarkcloudservices.com\",\n \"grant_type\": \"client_credentials\"\n}\n```\n\nUse the Production audience when calling the Production auth endpoint.\n\nThe response contains an `access_token` (a JWT) and an `expires_in` value. Cache and reuse the token until it is close to expiry.\n\n**2. Send on every API request:**\n- `Authorization: Bearer <access_token>`\n- `Account-Id: <your account id>`\n\nA `403` means your credentials are not entitled to that operation; contact support.\n\n## Billing\n\nA charge applies per vault when the first document is added to it.\n\n## Limits, errors and support\n\nOne document per upload; up to 60 per vault; PDF, DOC, DOCX, JPEG, PNG; 25 MB per file. API rate limits: up to 1,000 calls per minute per caller.\n\nStandard HTTP status codes apply (`400` validation, `401`/`403` authentication, `404` not found, `409` conflict, `413` too large, `429` rate limited, `5xx` server error). Error bodies use `problem+json`. Include the `lgsTraceResponse` header value when contacting support.\n\n**Support:** support@ochresoft.com | +44 (0)3300 366 700\n\n# Contract Pack Vault\n\n**Contract Pack Vault** is a conveyancing product on LandmarkConnect. You assemble a contract pack from your CMS and share it securely with the buyer's conveyancer. The API handles the building; the web app is where you review the pack and share it.\n\n## AI-assisted checking\n\nAs each document is added, it is automatically analysed so you can spot problems before the pack goes out. The checks include:\n\n- identifying and tagging each document by type,\n- flagging missing pages,\n- checking signatures are present where expected,\n- cross-checking addresses, names, dates and title/reference numbers against the case.\n\nThe results appear as a checklist in the web app for you to review and act on. They are not currently returned by the API.\n\n## Reviewing and sharing\n\nIn the web app you can review the checklist and analysis, preview, download or remove documents, update vault details, and share the vault with the buyer's conveyancer. The buyer's conveyancer receives secure access through a link once they have verified their email address.\n\n## Opening a vault from your CMS\n\nLink straight to a vault from your CMS using the vault `id` from `Create Document Vault`, so your team does not have to search for it in the web app. Open the relevant URL in a browser, replacing `{documentVaultId}`:\n\n- UAT: `https://uat-connect.landmark.co.uk/case/{documentVaultId}`\n- PRD: `https://connect.landmark.co.uk/case/{documentVaultId}`\n\n## API Specification Versions\n- **1.0.1** (16/07/2026)\n - Added `filename` property to `Add Document` endpoint body to show file name restrictions\n - Added `minLength` values to various schemas for clarity\n- **1.0.0** (08/07/2026)\n - Initial release\n"
