For Agents
Subscribe to Newie purchase, subscription, payment, and payout webhook events so an agent reacts to creator-economy revenue activity without polling.
Use for: Subscribe to Newie purchase events via webhook, Create a REST hook for new Newie subscriptions, I need to receive Newie payment events on my server, Set up a payout event webhook for Newie
Not supported: Does not handle payment processing, payout disbursement, or creator account management — use for REST hook subscription lifecycle against Newie events only.
Jentic publishes the only available OpenAPI specification for Newie Public API, keeping it validated and agent-ready. The Newie Public API offers a REST hooks implementation for provider integrations with the Newie creator-payments platform. Providers can verify their API token and create or destroy webhook subscriptions for purchase, subscription, payment, and payout events. Authentication uses an X-API-TOKEN header generated inside the Newie app.
Install Jentic One Beta
Connect the Newie Public API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Newie Public 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 | 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.
Capabilities
What an agent can do with Newie Public API.
Verify a Newie API token before establishing webhook subscriptions
Create REST hook subscriptions for purchase, subscription, payment, and payout events
Destroy an existing REST hook subscription to stop receiving events
Authenticate every request with an X-API-TOKEN header retrieved from the Newie provider app
Use a single subscription pattern across the four event types Newie supports
Use Cases
Patterns agents use Newie Public API for, with concrete tasks.
★ Real-Time Creator Revenue Webhooks
Creator platforms and revenue dashboards subscribe to Newie purchase, subscription, payment, and payout events so transactions appear instantly in their tooling. POST /restHooks_create registers a callback URL for the chosen event type and Newie pushes payloads to that URL as events occur, eliminating polling and matching the REST hooks pattern.
Call POST /restHooks_create with the desired event type ('purchase' or 'subscription' or 'payment' or 'payout') and the receiver URL; record the returned subscription id for later teardown.
Provider Token Validation
Before a provider integration goes live, GET /api_testAuth confirms the X-API-TOKEN issued in the Newie app is accepted. This catches misconfigured environment variables or rotated tokens during deployment instead of failing silently when real revenue events would be missed.
Send GET /api_testAuth with the configured X-API-TOKEN; block deployment if the response is not 200 so misconfigured credentials never reach production.
Webhook Lifecycle Management
Operations teams wire DELETE /restHooks_destroy into deprovisioning flows so when a customer cancels their integration the corresponding Newie subscription is torn down cleanly. This avoids stale receivers continuing to ingest payload they no longer have permission to handle.
On a customer cancellation event, call DELETE /restHooks_destroy with the stored subscription id and remove the subscription record from your own database.
AI Agent Revenue Event Reactor
An AI agent powering a creator's business operations uses Jentic to discover Newie operations, registers webhooks for the events it cares about, and reacts to each payload — for example sending a thank-you message on purchase events or reconciling payouts in the creator's accounting system, all without hand-coding the Newie client.
Use Jentic to search 'subscribe to newie purchase events', load POST /restHooks_create, execute it with the agent's ingestion endpoint, and route incoming purchase payloads to the thank-you message workflow.

Why Jentic?
Three things that make agents converge on Jentic-routed access.
Credential isolation
Newie X-API-TOKEN values are stored encrypted in the Jentic vault (MAXsystem). Agents receive scoped access tokens — raw API tokens never enter the agent's context.
Intent-based discovery
Agents search by intent (e.g., 'subscribe to creator payment events') and Jentic returns the Newie REST hook operations with their input schemas, so the agent can call the right endpoint without browsing docs.
Time to first call
Direct Newie integration: 1-2 days for token setup, REST hook lifecycle, and webhook handling. Through Jentic: under 30 minutes — search, load schema, execute.
Related APIs

Alternative
Stripe API
General payments platform with webhook events for charges, subscriptions, and payouts
Choose Stripe when the agent operates on a self-managed creator product with full payment processing; choose Newie when integrating with the Newie creator economy platform specifically.
FAQs
Specific to using Newie Public API through Jentic.
Why is there no official OpenAPI spec for Newie Public API?
Newie does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call Newie Public API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.
What authentication does the Newie Public API use?
Newie uses an X-API-TOKEN header carrying the API token retrieved inside the Newie app under Provider settings. Through Jentic, the token is stored in the encrypted MAXsystem vault and injected at request time so it never reaches the agent's context.
Can I subscribe to Newie purchase events through the Public API?
Yes. POST /restHooks_create accepts an event type and a target URL and registers a REST hook so Newie pushes purchase, subscription, payment, or payout payloads to that URL as events occur. DELETE /restHooks_destroy removes the subscription when no longer needed.
What are the rate limits for the Newie Public API?
Rate limits are not declared in the spec. Because the API is webhook-driven rather than polled, normal usage is small — one or two subscribe calls per integration plus periodic auth checks — so limits rarely become a concern.
How do I test a Newie webhook integration through Jentic?
Use Jentic to search 'verify newie api token', load GET /api_testAuth, and execute it. Then search 'subscribe to newie purchase events' and execute POST /restHooks_create with a temporary endpoint URL to confirm Newie pushes events as expected.
Is the Newie Public API free?
API access is included with a Newie provider account. Tokens are issued inside the Newie app once the provider account is approved — there is no separate API tier to purchase.
