WHMCS Integration

Good Day All,

Would it be possible to integrate GEODirectory and WHMCS using Hooks or the API? Have anybody done this?

We need to achieve the following:

1. Once a new user creates/sign-up an account with GEO, we need to create the user also in WHMCS using a hook or the Api.
2. Once the user orders a package from GEO, we will need to redirect them to a package on WHMCS to complete the order on WHMCS.
3. Payments and recurring invoices will be done by WHMCS, not GeoDirectory.
3. Once payment has been received via a payment gateway in WHMCS, using a hook or api, we “active” the listing for the user.
4. Monthly invoices will be sent to the user from WHMCS, not GEO.
5. Once payment confirmed the listing will be kept active or otherwise downgraded or disabled.

Comments welcome on which hooks or api calls needs to be used from GEO or WHMCS, to achieve the above results.

Thank you.
