# Use Coinvay payment links with a Kajabi offer

> Coinvay’s Kajabi kit uses an external hosted crypto checkout and a backend that grants a configured offer after verified payment. It is a custom integration, not a native Kajabi Payments provider or a replacement for recurring membership billing.

Connect external crypto checkout to a Kajabi offer with a protected catalog, verified payment and durable access-grant worker.

## Start with the offer and access model

Choose a staging offer, a fixed USD price and the Kajabi site that owns it. Confirm that your Kajabi account has the Public API access and permissions needed for the integration. Keep offer IDs, site IDs and catalog prices in protected server configuration. A customer-facing form may select an approved product, but it should not be allowed to choose an arbitrary offer to receive or invent the amount to pay.


## Connect checkout to a durable grant job

For a one-time course purchase, your backend creates the Coinvay invoice and records the intended buyer, offer, site and price. The course is not granted merely because the browser returns from hosted checkout. Verified payment creates one durable outbox job. A worker resolves the expected contact and offer, checks whether the grant already exists, and applies access once. This lets temporary API errors be retried without charging the customer again.


## Test email and membership consequences

Use a staging offer and an email address you control to observe the exact welcome messages and automations triggered by the grant. A successful API grant may initiate Kajabi email behavior that your business must configure. Check existing customers, duplicate notifications and worker crashes after a successful grant. The kit does not automatically revoke access on refund, manage membership renewals or implement subscription cancellation. A one-time access grant should not be described as a complete recurring entitlement system.


## Practical checklist

- Confirm current Kajabi API access and restrict credentials to the required operations.
- Keep catalog prices and allowed offer identifiers on the backend.
- Run staging tests for pending payments, duplicate grants, existing contacts and API outages.

## Questions and answers

### Can I paste only a checkout link into Kajabi?

You can share an invoice link, but automatic course access needs the configured backend and verified-payment worker. A link alone does not grant an offer.

### Will this replace Kajabi’s native subscription reporting?

No. The source kit performs external checkout and offer grants. Recurring billing, reporting reconciliation and access revocation require additional business-specific work.
