Zoho Inventory
Add Zoho Inventory to your product for your customers, and give your AI agents governed access to it.
Zoho Inventory is called through the regional Zoho API host, for example zohoapis.com/inventory/v1, and every request must carry organization_id as a query parameter even when the token reaches only one organisation. Auth is OAuth2 with a refresh token and scoped per module, and the data centre matters: a token issued in the EU will not work against the US host. The order flow is sales order, then package, then shipment order, so a carrier tracking number belongs to the shipment rather than the order, which trips up most first integrations. Items can be simple, composite or bundles, and stock is held per warehouse, so a quantity question is only answerable once a warehouse is named. Calls are metered as API credits per organisation per day rather than as a plain request count, so backfills need pacing. fastn keeps each customer's refresh token, regional host and organisation id together so calls never silently target the wrong tenant.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let a customer connect their own Zoho Inventory organisation so their items and stock levels appear in your product
Create sales orders in Zoho Inventory from orders placed in your own storefront, with the customer contact matched or created first
Show live per warehouse stock on a product page so sales staff stop promising items that are not there
Surface shipment tracking numbers and carrier status against the originating sales order for support staff
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
Ask an agent for the current stock of an item in a named warehouse, with the read scoped to that customer's organisation id
Have an agent create a purchase order for items below reorder level and log every create per tenant for audit
Let an agent explain why an order has not shipped by tracing sales order to package to shipment order
Example prompt
How many units of SKU 4471 are in the Manchester warehouse, and is anything on an open purchase order?
Set up Zoho Inventory in 4 steps
- 01Enable the Zoho Inventory connector from your fastn dashboard.
- 02Have each customer authorise their own Zoho Inventory account, so calls run under their credentials rather than a shared key.
- 03Decide which shipments, tracking events and orders your product needs, map those fields, then enable the actions and triggers you want.
- 04Call it from your product and expose it to your agents through the same governed connection.
Why teams use the Zoho Inventory integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Zoho Inventory integration without building it. Your customers connect their own Zoho Inventory account inside your product and work their shipments, tracking events and orders there, with no per-customer code on your side.
- Handle the part that actually costs time: tracking data arrives from many carriers in inconsistent formats and at unpredictable times. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a Zoho Inventory update is not your on-call problem.
- One integration serves your product and your agents. The same governed Zoho Inventory connection powers in-product features and gives AI agents scoped, audited access, so you keep physical movement and stock visible inside your product without wiring it twice.

QuickBooksZoho Inventory integration FAQ
How do I add a Zoho Inventory integration to my product?
Enable the Zoho Inventory connector in your fastn dashboard, then let each customer authenticate their own Zoho Inventory account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Zoho Inventory client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Zoho Inventory account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Zoho Inventory account and only ever sees their own shipments, tracking events and orders. That per-tenant isolation is the point of an embedded integration: you support the long tail of customer setups without maintaining an integration per customer.
Can AI agents use this Zoho Inventory integration?
Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. Ask an agent for the current stock of an item in a named warehouse, with the read scoped to that customer's organisation id
Who maintains the Zoho Inventory integration?
fastn does. When Zoho Inventory changes an endpoint, deprecates a field or alters its auth, the fix lands in the connector rather than in your backlog, and your customers' connections keep working.
Can I track shipments from Zoho Inventory inside my product?
Yes. Shipment and tracking events are read per customer and can trigger your workflows, so status changes surface in your product instead of your users checking a carrier site.
What does my product get back from Zoho Inventory as things move?
Whatever Zoho Inventory actually holds. Where it moves goods, that is shipment and tracking events, read per customer and delivered as they land. Where it holds stock, levels can be read on demand or kept in step through events, so your product is not deciding on a stale count. Where it carries orders and documents between trading partners, it is the acknowledgement, ship notice or status change that says what moved.
What can I build with the Zoho Inventory integration?
A common starting point: let a customer connect their own Zoho Inventory organisation so their items and stock levels appear in your product. Teams also use it for the other use cases listed above, and expose it to agents for governed reads and writes.
How much does the Zoho Inventory integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Zoho Inventory does not change your per-connector cost. You can start free with 3 connected accounts.
