We have released an add-on that takes the registration form out of the customer’s way: sign-in and registration via the MAX messenger.
The customer presses “Sign in with MAX” in the stock sign-in form, confirms the sign-in in a chat with your store bot and comes back to the storefront already signed in. No password to invent, no e-mail to confirm, no SMS code to wait for.
What happens underneath. The messenger sends the store the customer’s phone number together with a signature the store checks with the bot key — somebody else’s number cannot be substituted without that key. The store then looks the customer up by that number in every spelling it produces itself (brackets, spaces and dashes make no difference) and either lets them into their existing account with the whole order history, or registers a new customer.
What is in the add-on:
- a button in the stock sign-in form and in the sign-in pop-up — nothing to place by hand, no templates to edit;
- a “Register customers the store does not know yet” setting, so MAX sign-in can be kept for registered customers only;
- a sign-in attempt lifetime, with unfinished attempts clearing themselves up;
- the customer profile shows whether they sign in through MAX and offers an unlink button, so “I cannot log in” takes a minute;
- English and Russian for the interface and the bot messages, all of it editable in the store translations.
What the store needs: CS-Cart or Multi-Vendor 4.17.1 and above, a storefront on HTTPS, and your own bot in MAX. The bot is created for free in a few minutes through the service bot @MasterBot inside the MAX application; the manual walks through every step and every command.
What it does not do, so there are no surprises: it does not replace e-mail and password sign-in (the button stands next to it), it does not send letters or order notifications through the bot, and it does not open the admin panel — customers sign in through MAX, staff do not. The messenger does not pass an e-mail address on, so a new customer gets a placeholder address and can replace it in their account.
