Here are some of the things you can do: - Read and update sheets - Manage folders and workspaces - Administer Smartsheet plans and user accounts The [API resource specification](/#section/RESOURCES) includes object schemas, method speci. The API exposes 183 endpoints secured with bearer, oauth2 authentication.
Install Jentic One Beta
Connect the Smartsheet API Reference to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Smartsheet API Reference, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.
Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

Use Cases
Patterns agents use Smartsheet API Reference API for, with concrete tasks.
★ Productivity Operations
Use the Smartsheet API Reference to perform productivity operations programmatically. The API provides 183 endpoints covering core functionality including list contacts, get contact, list events.
Call GET /contacts to list contacts
Automated alternateEmailAddress Management
Automate alternateemailaddress operations by combining multiple Smartsheet API Reference endpoints. Agents can get contact and then list events in a single workflow.
Call GET /contacts/{contactId} to get contact, then verify the result
AI Agent Integration via Jentic
AI agents discover and call Smartsheet API Reference endpoints through Jentic without managing credentials directly. An agent searches for the required operation by intent, receives the matching endpoint schema, and executes the call with Jentic-managed authentication. This eliminates the need to read API documentation or handle bearer, oauth2 tokens manually.
Search Jentic for 'list contacts', load the operation schema, and execute with Jentic-managed credentials

Why Jentic?
Three things that make agents converge on Jentic-routed access.
Credential isolation
Smartsheet API Reference bearer, oauth2 credentials are stored encrypted in the Jentic vault (MAXsystem). Agents receive scoped access tokens — raw secrets never enter the agent context.
Intent-based discovery
Agents search by intent (e.g., 'list contacts') and Jentic returns the matching Smartsheet API Reference operation with its input schema, so the agent can call the right endpoint without browsing docs.
Time to first call
Direct Smartsheet API Reference integration: 1-3 days for auth handling, response parsing, and error cases. Through Jentic: under 1 hour — search, load schema, execute.

Can I list contacts with the Smartsheet API Reference?
Yes. Use the GET /contacts endpoint. The API returns structured JSON responses that agents can parse and act on directly.
What are the rate limits for the Smartsheet API Reference?
Rate limits are not specified in the OpenAPI spec. Check the vendor documentation for current limits. Through Jentic, rate limiting is handled automatically with retry logic built into the execution layer.
How do I list contacts through Jentic?
Install the Jentic SDK with pip install jentic, authenticate at https://app.jentic.com/sign-up, then search for 'list contacts'. Jentic returns the matching Smartsheet API Reference operation with its input schema. Load the schema and execute the call — credentials are injected automatically.
