Unarchiving an active template is a no-op. ## OpenAPI ````yaml /api-reference/openapi.json post /v1/templates/{id}/unarchive openapi: 3.0.0 info: version: 0.0.1 title: LithoBlocks API description: >- Manage templates, compile and send Slack messages, schedule delivery, build batch digests, and configure interactive workflows. Use /v1 paths and snake_case request fields. Authenticate with an organization-scoped API key in the Authorization: Bearer header. Each operation documents its required scope; a key without it receives 403 and required_scopes. A user's organization role limits which scopes a key can receive. Compiling and sending require messages:create; read access alone does not allow either operation. Create and manage keys in Integrations → API Keys. Store credentials in a secret manager, grant only the scopes needed, and use separate keys for each environment. Resources and credentials do not transfer between environments. Use code and request_id to diagnose API errors. The error field can be a string or a schema-validation object; consult the endpoint response schema for details. Resource list endpoints document their pagination and compatibility fields individually. See the documentation guides for API key lifecycle, the complete scope/role matrix, environment availability, input-schema discovery, and idempotent sending. The endpoint definitions below are the source for request and response contracts. contact: name: LithoBlocks url: https://lithoblocks.com email: support@lithoblocks.com servers: - url: https://api.lithoblocks.com description: Production (paths in this spec are rooted at /v1/...) - url: http://localhost:8787 description: Local dev (paths in this spec are rooted at /v1/...) security: [] paths: /v1/templates/{id}/unarchive: post: tags: - Templates summary: Unarchive a template description: >- Return an archived template to service with its versions and live version unchanged.
