Install Jentic One Beta

Connect the OneSignal API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the OneSignal 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.

For Agents

Send push notifications, email, SMS, and in-app messages to OneSignal audiences with a single notification creation endpoint.

Use for: I want to send a push notification to all subscribed users, Send a push to a specific OneSignal segment, Schedule a push for tomorrow at 9am UTC, Send an in-app message to users who match a tag filter

Not supported: Does not handle subscription import, segment editing, or message analytics - use for OneSignal notification creation only.

Use Cases

Patterns agents use OneSignal API for, with concrete tasks.

★ Transactional Push Notifications

Send order updates, password resets, and account notifications to specific OneSignal subscription ids using POST /notifications. The endpoint accepts the app id, target subscription ids, headings, contents, and optional data payloads, returning the created notification id for tracking.

Send a push notification with heading 'Order shipped' and body 'Your order is on its way' to subscription id 'abc-123' under app id 'app-xyz'.

Segment-Targeted Campaigns

Reach a curated audience of OneSignal subscribers by passing segment names or tag filters in the create-notification request. Segments are managed inside the OneSignal dashboard and referenced by name in the API call, so marketing teams can update audiences without redeploying code.

Send a notification to the 'Active Subscribers' segment with heading 'Weekly Update' and a deep link to the new content.

Agent-Driven Push via Jentic

Customer engagement agents send OneSignal notifications through Jentic without holding the REST API key. The agent searches for the send-notification intent, loads the schema, and executes the call with the message content supplied by upstream tooling.

Use Jentic search 'send onesignal notification' to locate POST /notifications, load the schema, and execute with the supplied app id and content.

Why Jentic?

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

Credential isolation

Your OneSignal REST API key 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 'send a push notification through onesignal', and Jentic returns the POST /notifications operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using OneSignal API through Jentic.

Why is there no official OpenAPI spec for OneSignal API?

OneSignal does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call OneSignal 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 OneSignal API use?

The API uses an apiKey credential - the OneSignal REST API Key sent in the Authorization header. Through Jentic the key lives encrypted in the vault (your Jentic One instance) and the agent only ever holds a scoped reference.

Can I send push notifications with this OneSignal spec?

Yes. POST /notifications accepts the app id, audience parameters such as segments or subscription ids, message content, and channel options, then queues the notification for delivery.

How do I target a OneSignal segment via the API?

Pass an included_segments array in the POST /notifications body with the segment names defined in the OneSignal dashboard. Combine with filters for finer targeting.

What are the rate limits for the OneSignal API?

Rate limits are not declared in this OpenAPI spec. Consult documentation.onesignal.com for current REST API rate limits before driving high-volume sends.

How do I send a notification through Jentic?

Run pip install jentic, search 'send onesignal notification', then load the POST /notifications schema and execute with the app id and message content. Jentic injects the REST API key from its vault.

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

Yes. Because you run Jentic One yourself, your own rules decide which operations and credentials the agent may use. This OneSignal surface exposes a single notification-creation operation, POST /notifications, which takes its target audience in the request body, so you can allow the agent only that one call. It creates notifications and does nothing else unless you add more operations to the allowed set.
