For Agents

Push new leads into a Clarkup sales pipeline after completing OAuth 2.0 authorization, suitable for inbound capture forms, chat handoff, or AI agent intake bots.

Install Jentic One Beta

Connect the Clarkup API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Clarkup API, 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 | sh

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 instance

Jentic 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.

Capabilities

What an agent can do with Clarkup API.

Initiate OAuth 2.0 authorization for a Clarkup workspace via /oauth/authorize

Exchange an authorization code for an access token via /oauth/token

Create a new lead in the connected Clarkup pipeline via /zapier/create-lead

View OpenAPI Document

Jentic publishes the only available OpenAPI specification for Clarkup API, keeping it validated and agent-ready. Clarkup is a sales pipeline tool focused on inbound lead capture, and its public API exposes a focused surface for OAuth authorization and lead creation. The spec covers the OAuth 2.0 authorization and token exchange endpoints plus a single Zapier-style lead creation endpoint that drops a new lead into a Clarkup pipeline. It is intentionally minimal and aimed at integration partners that need to push leads in, not browse or enrich the existing pipeline.

Use Cases

Patterns agents use Clarkup API for, with concrete tasks.

★ Inbound Lead Capture from Web Forms

Forward web form submissions, webinar registrations, and chatbot handoffs straight into Clarkup as new leads after a one-time OAuth connection. The /zapier/create-lead endpoint accepts the lead payload directly so partner integrations skip building a heavier sync layer.

Call /zapier/create-lead with the contact's name, email, source, and notes after a form submission, using the cached OAuth bearer token.

Partner OAuth Onboarding

Run a one-click OAuth connection flow that lets a Clarkup user authorise a third-party app to push leads into their workspace. The /oauth/authorize redirect kicks off consent and /oauth/token exchanges the resulting code for a refresh-capable access token.

Redirect the user to /oauth/authorize with client_id, scope, and redirect_uri, then post to /oauth/token with the returned code to obtain an access token.

AI Agent Lead Intake via Jentic

An AI agent that runs an outbound prospecting bot or an inbound concierge can drop qualified leads into Clarkup at the moment of capture by searching Jentic for the lead-creation operation and executing it. Jentic securely stores the OAuth bearer token so the agent never holds the secret directly.

Use the Jentic search query 'create a sales lead' to find /zapier/create-lead and execute with the qualified contact details from the conversation.

Why Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Your Clarkup token is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'create a lead in Clarkup', and Jentic returns the matching operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Clarkup API through Jentic.

Why is there no official OpenAPI spec for Clarkup API?

Clarkup does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call Clarkup API via structured tooling. It is validated against the live API and kept up to date. Get started with Jentic One, the self-hosted execution layer.

What authentication does the Clarkup API use?

The API uses OAuth 2.0 authorization code flow via /oauth/authorize and /oauth/token, returning a bearer token used on /zapier/create-lead. Through Jentic the bearer token is stored in the encrypted vault and the agent receives only a scoped execution context.

Can I create a Clarkup lead with the API?

Yes. POST to /zapier/create-lead with the lead payload after completing the OAuth flow. This is the only lead-mutation endpoint in the public spec, designed for inbound capture rather than full pipeline management.

Can I read existing Clarkup leads or pipeline stages with this API?

No. The public spec only exposes lead creation and OAuth endpoints. To read or move existing leads, use the Clarkup app directly until additional endpoints are released.

How do I push a lead into Clarkup through Jentic?

Search Jentic for 'create a sales lead', load the schema for /zapier/create-lead, and execute with the lead details. The Python SDK uses await client.search, await client.load, await client.execute.

How do I complete the OAuth handshake?

Send the user to /oauth/authorize with client_id, scope, and redirect_uri. After consent Clarkup redirects with a code that you exchange at /oauth/token to receive an access token.

Can I limit what my agent is allowed to do with the Clarkup API?

Yes. Because you run Jentic One yourself, you decide which Clarkup operations the agent may call, and your own rules are what allow or block each one. You can restrict the agent to the /zapier/create-lead operation for inbound lead creation while leaving the /oauth/authorize and /oauth/token operations out of the allowed set unless you add them. The stored token is injected only at execution time, so the agent acts only within the operations you have permitted.
