LabArchives Integration

Use LabArchives APIs only from current, official method pages. The public documentation is a shared notebook, not a versioned SDK reference, so verify the specific page immediately before implementing a remote operation.

Choose the Correct Surface

Do not combine these interfaces:

• Legacy ELN API: notebook trees, entries, attachments, users, searches, exports, and site-license functions. It uses regional *api.labarchives.com hosts, /api/<class>/<method> paths, XML for many responses, and signed query parameters.
• Inventory API v1: inventory, item types, orders, storage locations, and vendors. It documents relative /public/v1/... paths, JSON response schemas, and signed X-LabArchives-* request headers.
• Product integrations: Jupyter, REDCap, Protocols.io, GraphPad Prism, SnapGene, Geneious, and others are product-specific UI or file workflows. They are not evidence of a general LabArchives OAuth 2.0 API.

Read references/api_reference.md before writing API code and references/integrations.md before automating an advertised integration.

Access and Credentials

LabArchives ELN developer API access is an Enterprise capability. The current Inventory FAQ limits Inventory API access to Enterprise and Enterprise Plus licensees and requires an Inventory account with API permission. Contact the institution's LabArchives team or LabArchives support for access and the development documentation supplied with it.

The environment names below are conventions of this skill, not vendor-defined standards:

• LABARCHIVES_ELN_API_URL — one exact regional ELN API URL ending in /api
• LABARCHIVES_ACCESS_KEY_ID — LabArchives-issued Access Key ID (akid)
• LABARCHIVES_ACCESS_PASSWORD — HMAC signing secret
• LABARCHIVES_USER_ID — optional persistent UID bound to that Access Key ID
• LABARCHIVES_INVENTORY_LAB_ID — required for lab-scoped Inventory requests; omitted during GET /public/v1/users/me lab discovery

Keep secrets in the process environment or an approved secret manager. Do not put them in YAML, source code, command-line arguments, prompts, logs, notebooks, or committed .env files. The bundled tools never search for .env files.

From this skill directory:

uv run scripts/setup_config.py regions
uv run scripts/setup_config.py check --require-user-id

setup_config.py validates only endpoint structure and named-variable presence; it does not authenticate, persist, or print credentials. See references/authentication_guide.md.

Regional Endpoints

Browser login hosts and API hosts are different. The official ELN API overview currently lists US/rest of world, Australia/New Zealand, UK, Europe outside the UK, and Canada API hosts. The help center separately lists the five regional browser login hosts.

Use setup_config.py regions for the current allowlist and the complete table in the authentication guide. Never build an API URL from a browser login URL.

The Inventory overview publishes https://iapi.labarchives.com as its API base URL; append the documented /public/v1/... route. No regional base-URL table is published there. Confirm any regional deployment with the institution/vendor; do not transform an Inventory browser login host into an API hostname.

Authentication Model

ELN requests

The official algorithm is fully documented:

1. Set expires to the current Unix epoch time in milliseconds, adjusted for server clock difference if necessary. Despite its name, it is not a future expiry time.
2. Concatenate, with no separators: <Access Key ID><API method name><expires>.
3. Compute HMAC-SHA-512 using the Access Password as the key.
4. Base64-encode the digest.
5. URI-encode that signature and send akid, expires, and sig as the documented query parameters.

For ordinary ELN calls, the signature input is the method name only, not the API class. User authorization is a documented special case: signing the api_user_login redirect uses the unencoded redirect URI in place of a method name.

Inventory API v1 requests

Inventory shares the HMAC algorithm but signs the exact relative route, including resolved path parameters and excluding the query string. Its authentication page documents these headers:

• X-LabArchives-UId
• X-LabArchives-AKId
• X-LabArchives-LabId
