For Agents

Manage orders, products, inventory, warehouses, and channel integrations across an Extensiv-connected 3PL or brand operation through OAuth2-authenticated REST endpoints.

Connect the Extensiv Integration Manager API to your agent

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

Install Jentic One Beta (Self-Hosted)

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

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.

Jentic publishes the only available OpenAPI specification for Extensiv Integration Manager API, keeping it validated and agent-ready. Extensiv (formerly 3PL Central) Integration Manager is a multi-channel hub that connects ecommerce storefronts, warehouses, and order-management systems for third-party logistics providers and brands. The API exposes 12 endpoints across orders, products, inventory, warehouses, and integrations, secured with OAuth2 client credentials. Typical use is order routing, inventory sync, and warehouse-of-record updates between Shopify-class storefronts and 3PL fulfilment systems.

Use Cases

Patterns agents use Extensiv Integration Manager API API for, with concrete tasks.

★ Order Sync Between Storefront and 3PL

Use POST /orders to push new orders from a storefront into Extensiv, GET /orders to reconcile state, and PUT /orders/{id} to amend in-flight orders. This handles the most common Integration Manager workflow: keeping a 3PL's order book aligned with the brand's source-of-truth storefront. Saves manual re-keying for ops teams managing multiple ecommerce channels.

Call POST /orders with the new storefront order payload, then GET /orders/{id} to confirm Extensiv accepted it and assigned a warehouse.

Inventory Visibility Across Warehouses

GET /inventory returns inventory levels across the warehouses connected to the account, and GET /warehouses lets the agent enumerate the warehouse set. Combined, these power dashboards or alerts when stock dips below a threshold in any warehouse, and let an agent route a new order to the warehouse with the right stock.

Call GET /inventory, group results by warehouse and SKU, and flag any SKU whose total quantity is below the configured reorder threshold.

Product Master Replication

GET /products and POST /products together let an integration replicate a product master into Extensiv, while GET /products/{id} fetches a specific product to verify state. This is the foundation for multi-channel listings: the same product flows from a PIM into Extensiv and then out to each connected storefront.

Call POST /products with the new product payload from the PIM, then GET /products/{id} to confirm Extensiv stored the SKU and channel mapping.

AI Operations Agent via Jentic

An AI ops agent uses Jentic to call Extensiv Integration Manager operations on demand — for example, escalating to ops when an order is stuck, or rewriting a shipping address provided by a customer. Jentic resolves intents like "update an extensiv order" to PUT /orders/{id} and supplies the OAuth2 access token from the vault.

Through Jentic, search 'update an extensiv order', load PUT /orders/{id}, and execute it with the customer's corrected shipping address.

Why though Jentic?

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

Credential isolation

Extensiv OAuth2 client credentials sit encrypted in the Jentic vault. Jentic mints access tokens on demand and injects them as bearer headers per request, so the long-lived secret never enters the agent's prompt, memory, or logs.

Intent-based discovery

Agents search Jentic by intent (e.g., 'create an extensiv order' or 'list warehouse inventory') and receive the matching operation with its path and body schema, so the agent calls the right endpoint without parsing developers.extensiv.com.

Time to first call

Direct Extensiv integration: 3-5 days for OAuth2 setup, order shape mapping across channels, and reconciliation logic. Through Jentic: under 1 hour — search, load, execute.

Related APIs

Alternatives and complements available in the Jentic catalogue.

Alternative

ShipBob API

ShipBob is a 3PL with its own direct fulfilment API

Pick ShipBob when fulfilment runs entirely in ShipBob warehouses; pick Extensiv when orchestrating across multiple 3PLs and channels.

Alternative

ShipStation API

ShipStation focuses on label generation and carrier integration for direct shippers

Choose ShipStation for in-house shipping label workflows; choose Extensiv when the operation spans third-party 3PL warehouses and channel integrations.

Complementary

Twilio API

Twilio handles customer SMS notifications when an Extensiv order ships or has issues

Use Twilio for the customer-comms leg of the workflow and Extensiv for the order and fulfilment leg.

FAQs

Specific to using Extensiv Integration Manager API API through Jentic.

Why is there no official OpenAPI spec for Extensiv Integration Manager API?

Extensiv does not publish a public OpenAPI specification covering Integration Manager. Jentic generates and maintains this spec so that AI agents and developers can call Extensiv Integration Manager 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 Extensiv Integration Manager API use?

Authentication is OAuth2. The spec declares an oauth2 security scheme; in practice client credentials are exchanged for a bearer access token that is sent on subsequent calls. Through Jentic, client credentials sit in the vault and tokens are minted on demand, so the long-lived secret never enters the agent's prompt or logs.

Can I update an order after it has been created?

Yes, while the order is still amendable. Call PUT /orders/{id} with the updated payload to change shipping address, line items, or other fields supported by Extensiv. Once the order has progressed in fulfilment, certain fields may be locked — check the response body for an explicit error.

Does this spec cover shipment tracking?

These 12 endpoints cover orders, products, inventory, warehouses, and integrations. Shipment tracking surface is not in this subset; tracking data typically appears as fields on the order resource returned by GET /orders/{id}, so check that payload for tracking numbers and carrier identifiers.

How do I push a new order into Extensiv through Jentic?

Run pip install jentic, then search 'create an extensiv order', load the POST /orders operation, and execute it with the order JSON. Jentic mints an OAuth2 access token and injects it as a bearer header at execution time.

What are the rate limits for the Extensiv API?

Rate limits are not declared in this spec. Extensiv applies per-tenant limits in production; treat 429 responses as authoritative and back off using any Retry-After header returned. For bulk sync workloads, contact Extensis support to confirm headroom.
