For Agents
Create users, track events, update attributes, and manage lists in Engage.so for lifecycle messaging campaigns.
Use for: I need to create a new user in Engage.so, Track a 'subscription started' event for a user, Update a user's plan attribute after an upgrade, Add multiple users to a marketing list
Not supported: Does not handle email template design, in-product surveys, or push-notification device registration - use for managing users, events, lists, and batch operations in Engage.so only.
Jentic publishes the only available OpenAPI specification for Engage.so API, keeping it validated and agent-ready. Engage.so is a customer messaging and lifecycle platform; the API exposes user creation, attribute updates, event tracking, list and segment management, and a batch endpoint for combining many operations in one request. Product and growth teams use it to feed user behaviour into Engage.so so the platform can run multi-channel campaigns based on real activity. The 11-endpoint surface keeps integration simple while covering the full lifecycle data model.
Install Jentic One Beta
Connect the Engage.so API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Engage.so 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://jentic.com/install.sh?src=apis&api=%2Fapis%2Fengage.so%2Fengage-so" | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fengage.so%2Fengage-so" | 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 Engage.so API.
Create or update a user record so campaigns have someone to target
Track a user event such as 'order placed' or 'feature used'
Update user attributes used by campaign segmentation rules
Manage lists and add or remove subscribers from them
Send many requests at once via the batch endpoint to reduce round trips
Use Cases
Patterns agents use Engage.so API for, with concrete tasks.
★ Product Event Tracking
When a user takes a meaningful action - sign-up, plan upgrade, churn - the agent calls POST /users/{id}/events to record it in Engage.so. Engage.so's segmentation engine then uses those events to trigger lifecycle messages without the product team having to maintain campaign logic in their own backend.
On 'subscription_started' in the product, POST the event to Engage.so for the relevant user with plan and amount attributes
User Sync from Product Database
Use POST /users to create or update user records and PUT /users/{id} to keep their attributes current. Combined with /batch, this enables periodic syncs from a product database into Engage.so so audience segments stay accurate.
Sync a list of 50 newly signed-up users into Engage.so via POST /batch with one create-user operation per user
List Management for Campaigns
Create campaign lists with POST /lists, then add or remove subscribers with POST and DELETE /lists/{list_id}/subscribers. This lets a marketing automation agent maintain audience lists in response to real product events without manual list management.
Create a list called 'beta-users' and add user_ids 100 through 110 as subscribers
Agent-Driven Lifecycle Messaging
An AI agent monitoring product events searches Jentic for 'track a user event' or 'add user to list', loads the Engage.so operation, and executes against the matching endpoint. This wires Engage.so into a single agent that handles the whole 'detect > track > segment' loop.
When a user upgrades, update their plan attribute and add them to the 'paid' list in two operations via POST /batch

What agents get from Jentic-routed access to this vendor.
Setup
Wiring the Engage.so API by hand means setting up its basic auth, formatting user, event, list, and batch calls, and handling your own errors against https://api.engage.so/v1. Through Jentic you install once, import the Engage.so API from the API Directory, store the credentials once, and your agent calls it.
Permission scoping
The Engage.so API puts the user id in the URL path (/users/{id}), so a rule can pin your agent to one user: it can read and update that user and track events for it and nothing else. You choose the operations it may call, so ones like deleting a user or running a batch are not included unless you add them.
Credential isolation
Your Engage.so credentials are stored once, encrypted, by your own Jentic One instance and injected at execution time. They never enter the agent's prompt, logs, or context.
Intent-based discovery
Agents search Jentic by intent such as 'update a user profile' or 'track a user event', and Jentic returns the matching Engage.so operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs
Specific to using Engage.so API through Jentic.
Why is there no official OpenAPI spec for Engage.so API?
Engage.so does not publish an OpenAPI specification through public channels. Jentic generates and maintains this spec so that AI agents and developers can call Engage.so 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 Engage.so API use?
Engage.so uses HTTP Basic authentication via the `basicAuth` security scheme. Through Jentic, the credentials are stored encrypted in the vault and applied at execution time so they never appear in the agent's context.
Can I track product events in Engage.so via the API?
Yes. POST /users/{id}/events records a behavioural event against a user. Engage.so then uses those events to power segmentation rules and lifecycle campaigns.
How does the batch endpoint work?
POST /batch accepts an array of sub-requests so an agent can create users, track events, and add subscribers in a single round trip. This is the recommended path for high-volume syncs.
What are the rate limits for the Engage.so API?
The OpenAPI spec does not declare rate limits. Engage.so applies workspace-scoped throttles in production; back off on HTTP 429 responses and consult their developer docs for the exact ceiling on your plan.
How do I track a user event through Jentic?
Run `pip install jentic`, search 'track a user event in engage.so', and Jentic returns POST /users/{id}/events with its input schema. The agent supplies the user id, event name, and properties, then executes against base URL https://api.engage.so/v1.
Can I limit what my agent is allowed to do with the Engage.so API?
Yes. Because you run Jentic One yourself, your own rules decide which Engage.so operations and credentials the agent may use. Since the API carries the user id in the URL path (/users/{id}), a rule can pin the agent to a single user so it only reads and updates that user and tracks events for it. You also choose which operations are exposed, so higher-impact calls like deleting a user (DELETE /users/{id}) or running POST /batch stay off unless you add them.
