Just before I give an update, I find on every forum I've visited, the original request/poster getting derailed.
Example: Q: "Where can I find cheap HIV treatment?"
Forum Answers: "Why did you get HIV in the first place ? Did you share needles ?" etc.. etc..
I believe if someone really wants to know the true answer for using Wordpress, you can add me or anyone else who uses it on a Voice Calling App, and have a proper conversation.
There are many use cases and reasons for it. So you can PM me your Skype/Wechat/Whatsapp/Line/Signal anything you want, and we can do a call and talk about alternatives and ideas.
But for this thread, onto the task.
Update on Development:
I've had my developers successfully integrate it, where user updates their email, password, service, and things sync to Wordpress.
The only issue, is its done by editing Blesta on the code level. Not by "plugin". This is not going to be good for patching/updates to Blesta, therefore I don't see it as a realistic solution.
The one open issue that cant be done in the plugin, is the password. Once this can be done, then plugin will be complete, and it can survive any Blesta updates.
We have reviewed API docs, handlers, etc.. and cannot find a "trigger" that alerts or sends the new password (user changes their password) to a "handler" or some call, so our Plugin can take that and apply to Wordpress DB.
If anyone knows the solution, or can get Blesta Dev's to have it created, then we can finalize the integration.
Until then, we will roll on with WHMCS.
Bonus:
I believe what makes WHMCS-WP integration work (with password changes) is their API for it.
They have:
https://developers.whmcs.com/api-reference/getclientpassword/
https://developers.whmcs.com/api-reference/decryptpassword/
https://developers.whmcs.com/api-reference/encryptpassword/
I'm not trying to start a battle here or anything, just sharing information that could get Blesta improved and more utilized across various integrations.
Thanks everyone, and continued success.
