Install Jentic One Beta

Connect the Google Play Custom App Publishing API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Google Play Custom App Publishing 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

Publish a private Android app to specific managed Google Play enterprise organisations from a developer account.

Use for: I need to publish a private Android app to a specific enterprise organisation, Create a custom app for a managed Google Play customer, Register a new private app under our developer account, Set up a custom app for internal-only distribution

Not supported: Does not upload APKs, manage release tracks, or list public store apps - use only to register a private app under a developer account scoped to enterprise organisations.

Use Cases

Patterns agents use Google Play Custom App Publishing API for, with concrete tasks.

★ Private Enterprise App Rollout

An IT team building an internal-only Android app for their workforce uses the Custom App Publishing API to register the app under their developer account and bind it to their enterprise organisation ID in one call. The app does not appear in the public Play Store and bypasses the public-listing review path. After registration, the team uses the Android Publisher API to upload AAB binaries and manage release tracks.

POST /playcustomapp/v1/accounts/{account}/customApps with body {title: 'Acme Inventory', languageCode: 'en-US', organizations: [{organizationId: '01a2b3c4'}]} to register the app for a single enterprise.

MDM Onboarding Flow

A mobile device management vendor automates the creation of customer-specific app variants when onboarding a new managed Google Play customer. The API call provisions the app, returns the package name, and the MDM platform then triggers the binary upload through Android Publisher. End-to-end onboarding drops from a manual multi-day Play Console process to under an hour.

Call POST /playcustomapp/v1/accounts/{developerAccount}/customApps with the customer's organizationId, capture the returned packageName, and queue an AAB upload job for that package.

AI Agent App Publishing via Jentic

An automation agent that handles app release workflows can call the Custom App Publishing API through Jentic to register new private apps without the developer juggling OAuth scopes or Play Console steps. Jentic stores the developer's refresh token in its vault and exposes the customApps.create operation as a single search-load-execute flow, turning a 30-minute manual setup into a one-step agent call.

Search Jentic for 'create a Google Play custom app', load the customApps.create schema, and execute it with the developer account ID, app title, languageCode, and organizationId.

Key Endpoints

Why Jentic?

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

Credential isolation

Your Google Play developer OAuth credential 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 Google Play custom app', and Jentic returns the customApps create operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Google Play Custom App Publishing API through Jentic.

What authentication does the Google Play Custom App Publishing API use?

It uses OAuth 2.0 with the https://www.googleapis.com/auth/androidpublisher scope and requires a Google Play developer account. Service accounts are typically used for automation. Through Jentic the refresh token is stored in the vault and a scoped access token is minted at call time.

Can I upload an APK with this API?

No. The Custom App Publishing API only registers a new app and binds it to enterprise organisations through POST /playcustomapp/v1/accounts/{account}/customApps. APK and AAB uploads, release tracks, and listings are handled by the separate Android Publisher API once the app exists.

What are the rate limits for this API?

Like other Google Play developer APIs it follows project-level Google Cloud quotas. Default limits are conservative because custom-app creation is a low-volume administrative operation; raise the quota in Google Cloud Console if onboarding many enterprises in parallel.

How do I create a custom app through Jentic?

Run jentic search 'create a Google Play custom app', load the schema for POST /playcustomapp/v1/accounts/{account}/customApps, and execute it with the developer account ID, app title, language code, and the target organizations array.

Is the Google Play Custom App API free?

There is no per-call charge for the API itself, but it requires an active Google Play developer account, which has a one-time registration fee. Standard Google Cloud project quotas apply.

Can I make a custom app available to multiple enterprises at once?

Yes. The customApps.create body accepts an organizations array, so a single call can bind the new app to several enterprise organisation IDs. Additional enterprises can be added later through Play Console or by republishing.

Can I limit what my agent is allowed to do with the Google Play Custom App Publishing API?

Yes. Because you run Jentic One yourself, your own rules decide which operations and credentials the agent may use. Since the developer account sits in the URL path (/playcustomapp/v1/accounts/{account}/customApps), you can pin the agent to a single developer account, and you can restrict it to just the custom-app registration call so it cannot reach any other operation. Nothing beyond registering a private app scoped to your enterprise organisations is available unless you add it.
