# OpenGov

> OpenGov builds cloud ERP and public service software for state and local government, serving more than 2,000 communities. The OpenGov Public Service Platform publishes a developer portal at developer.opengov.com with ten OpenAPI 3.x definitions covering roughly 358 operations across Permitting & Licensing, Budgeting & Performance, Procurement & Contract Management, Purchase Orders, Receipts, Vendor Management, Enterprise Asset Management and Open Data (CKAN). Access requires an OpenGov customer account — the specs and docs are fully public, the credentials are not.

Generated by API Evangelist on 2026-08-04. OpenGov publishes its own llms.txt at https://developer.opengov.com/llms.txt (a link index of the portal's markdown docs); this file is the catalog-side companion covering the API surface and the artifacts derived from it.

## Authentication

- Integration API key in an `Authorization: Token <key>` header, issued per integration in the Developer Portal (Permitting & Licensing).
- `X-API-KEY` or `Authorization` key generated in the product Control Panel (Budgeting & Performance, Procurement family).
- Bearer JWT (Vendor Management, Purchase Order, Receipt).
- OAuth 2.0 client_credentials via Auth0 at https://accounts.viewpointcloud.com/ (Permitting & Licensing openIdConnect scheme). Discovery: https://accounts.viewpointcloud.com/.well-known/openid-configuration
- Session cookie via `POST /api/v1/authenticate` (Enterprise Asset Management only).
- `Authorization: Bearer <API key>` for SCIM 2.0. OAuth and Basic Auth are not supported for SCIM.

Authorization is by named permission grants per integration (Record Read, Record Write, Workflow Write, …) plus per-Record-Type access. An administrator can only grant permissions they personally hold.

## Events

- 31 Permitting & Licensing webhook events, HMAC-SHA256 signed with a per-subscription secret over `"<X-Webhook-Timestamp>.<raw body>"`, `X-Webhook-Signature: sha256=<hex>`, 5-minute replay tolerance, OPTIONS origin handshake against https://webhooks.opengov.com
- No events for Enterprise Asset Management, Procurement or Vendor Management ("No events available yet")
- No AsyncAPI document is published

## What OpenGov does not publish

- No client SDK in any language, and no CLI
- No sandbox, test mode or test credentials — the API Test Console runs against live production data
- No `/.well-known/security.txt`, no `/.well-known/api-catalog`, no A2A agent card
- No first-party MCP server (the npm `opengov-mcp-server` package is third-party and targets Socrata)
- No deprecation policy, no Sunset/Deprecation headers, no SLA, despite two suites already shipping a superseded v1
- No published rate-limit quota, no 429 response, no Retry-After
- No RFC 9457 problem details — errors are either a JSON:API `errors[]` array or a flat `{status, code, detail}` object
