Zoho Billing
Add Zoho Billing to your product for your customers, and give your AI agents governed access to it.
Zoho Subscriptions became Zoho Billing, and the rename brought a broader product, but the recurring revenue model underneath is unchanged: plans, the addons attached to them, coupons, and the subscriptions that reference all three against a customer. Two things are worth designing around. Addons come in two kinds, one-time and recurring, and confusing them is how somebody gets billed every month for a thing they bought once. And collection normally runs through a hosted page: your product creates the page and sends the user to it, so card details never pass through your servers and your integration deals in subscriptions rather than payment instruments. Subscription state is not a boolean either, since trialling, live, unpaid and non renewing are four different answers to the question of whether access should continue. There is no general ledger in here, and accounting posts through to Zoho Books, so treat this as billing rather than bookkeeping.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let each customer connect their own Zoho Billing organisation so subscriptions are created and amended from inside your product.
Create a hosted page for a signup or an upgrade, so card details go straight to the payment page and never touch your systems.
Attach a one-time or a recurring addon deliberately, since the two bill very differently for what looks like the same purchase.
React to a subscription going unpaid, non renewing or cancelled, so entitlement follows the billing state rather than lagging behind it.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent explains what a customer is subscribed to, which addons sit on it, and what renews next.
An agent puts through an approved plan change or coupon within scoped permissions, idempotently and logged.
An agent lists subscriptions sitting unpaid and how long each of them has been stuck.
Example prompt
What is this customer subscribed to, which of their addons recur, and when does the next charge fall?
Set up Zoho Billing in 4 steps
- 01Enable the Zoho Billing connector in your fastn dashboard.
- 02Have each customer authorise their own billing organisation, which longer-standing accounts may still know as Zoho Subscriptions.
- 03Map the plan, addon and subscription fields your product uses, decide where a hosted page takes over, and enable the webhooks you act on.
- 04Call it from your product and expose the same connection to your agents through the MCP gateway.
Why teams use the Zoho Billing integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Zoho Billing integration without building it. Your customers connect their own Zoho Billing account inside your product and work their orders, payments and customers there, with no per-customer code on your side.
- Handle the part that actually costs time: money and order state must never be double-applied, and reconciliation has to be possible. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a Zoho Billing update is not your on-call problem.
- One integration serves your product and your agents. The same governed Zoho Billing connection powers in-product features and gives AI agents scoped, audited access, so you keep commerce and payment records in step with your product without wiring it twice.

DocusignZoho Billing integration FAQ
How do I add a Zoho Billing integration to my product?
Enable the Zoho Billing connector in your fastn dashboard, then let each customer authenticate their own Zoho Billing account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Zoho Billing 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 Billing account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Zoho Billing account and only ever sees their own orders, payments and customers. 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 Billing integration?
Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. An agent explains what a customer is subscribed to, which addons sit on it, and what renews next.
Who maintains the Zoho Billing integration?
fastn does. When Zoho Billing 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.
Is the Zoho Billing integration safe for payment and order writes?
Writes are idempotent, so a retry cannot double-charge or duplicate an order, and every call is logged per tenant so a transaction can be reconciled against the event that triggered it.
Can my product react to a new order, payment or refund immediately?
Yes, through event triggers, so fulfilment, entitlement or accounting steps run as soon as the event lands rather than on a nightly sync.
What can I build with the Zoho Billing integration?
A common starting point: let each customer connect their own Zoho Billing organisation so subscriptions are created and amended from inside 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 Billing integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Zoho Billing does not change your per-connector cost. You can start free with 3 connected accounts.
