Make an authenticated request

Credentials stay in environment variables and every read is tenant scoped. This request only reads; the full quickstart creates, approves and posts a journal entry.

export INVARENT_BASE_URL="https://api.invarent.com"
export INVARENT_API_KEY="<a key with the tenant:read scope>"

curl "$INVARENT_BASE_URL/v1/tenant" \
  -H "Authorization: Bearer $INVARENT_API_KEY"

One contract across five controlled phases

The runtime is a source-derived superset of the canonical target.

01

Ledger & platform

Tenant setup, journals, approvals, reports, webhooks, audit, and usage.

02

GAAP operations

AP, AR, cash, payroll, assets, revenue schedules, and close controls.

03

Job cost & GovCon

Projects, contracts, CLINs, WBS nodes, cost pools, and indirect rates.

04

AI & controls

Evidence-bearing suggestions with explicit approve and reject boundaries.

05

Tax & year-end

Tax packages, report snapshots, filing gates, and access evidence.

03

Generated clients and machine-readable contracts

SDKs are generated from the OpenAPI contract and live in the repository at packages/contracts/sdk/runtime/typescript and packages/contracts/sdk/runtime/python. npm and PyPI packages are planned, not published — until then, use the repository sources or generate a client from the hosted contract.

TypeScript

Planned: npm packagepackages/contracts/sdk/runtime/typescript

Typed paths, request bodies, responses, and OAuth form serialization, generated by openapi-typescript.

Python

Planned: PyPI packagepackages/contracts/sdk/runtime/python

Synchronous HTTPX client covering the runtime operations, including literal :approve-style action paths.

# Generate a TypeScript client from the hosted OpenAPI 3.1 contract
npx openapi-typescript https://invarent.com/openapi.json \
  -o ./invarent-api-schema.d.ts

# Python: a standard OpenAPI generator covers most operations. The checked-in
# client keeps literal :approve-style action paths that generic generators
# commonly misread as extra path variables.
pip install openapi-python-client
