[SOLVED] Joomdonation EventBooking CB integration

I'm working with Event Booking ( joomdonation.com/joomla-extensions/events-booking-joomla-events-registration.html ) component that integrates with CB - when user registers for an event, the EB has option that allows to simultaneously create user account. It sort of works fine - except it mingles with and between Joomla CMS user registration and CB which creates little havoc - example:
CB is set as primary registration (CMS disabled); email confirmation enabled
1) user signs up for an event and CB account is created;
2) user receives email from EB confirming it's registration;
3) user receives email via Joomla CMS (instead of CB) - at this point we have a break, because confirmation link is now generated by Joomla CMS process and user remains inactive (until admin manually updates the account - not desirable in this case) + user will not receive welcome email

I have contacted Tuan @ joomdonation.com and here is his response:

Hi Andrzej

Actually, right now, we could not use CB settings as you mentioned. I will try to contact CB developer to see whether they provide an API for them to call.

Right now, the integration is just simple like that :
1. The account is created using Joomla core API. So actually, the email is sent using Joomla core, not using CB
2. After the account is created, the extension try to update CB custom fields data base on what users entered on registration form in Events Booking

So unless CB has API call to allow us to create an account, it is almost to impossible to implement what you requested here.

Tuan

Could you please advise how to proceed with it - thanks so much!

They need to register users through CB API instead of Joomla. Examples of how to do this with CB 2.x API as follows.

Thanks Kyle - is there a CB API book/tutorial, etc. I can download?

No, the above links are all that's needed to register a user. Can also review the registration action in CB Auto Actions found below for working example.

Kyle - we are running into some hiccups here while trying to work on this. Can you please confirm that this link to the API is still correct guide: www.joomlapolis.com/support/tutorials/120-api-usage/18360-sending-emails-through-cb - thanks

No, see my replies above. I've provided links to up to date API usages as well as location for CB Auto Actions registration action, which can be used as an example.
