The registration form is your one chance to collect customer information at the moment they're willing to give it. You configure it in Setting > Register form Management by choosing which fields to collect and which are mandatory. The setting applies only to people who sign up from now on — existing members and their point balances are untouched.

⚡ Quick Path: Setting → Register form Management → click the bar of the field you want on → set the Required Field switch → Save

Requirements before you start

  • An account with the Admin Role — you need access to Setting > Register form Management.
  • A team decision on what you're collecting — if a field is added later, every member who signed up before it existed has no data in it.
  • At least one branch, if you plan to enable the branch field — see the How to set up branches for the member registration form article.
  • A phone to test with — the signup link opens both in the LINE app and in an ordinary browser, so you can check the real result afterwards.

What to consider when building the form

The more boxes the form asks for, the longer signup takes. Collecting only what you will actually use works better than turning everything on. Before enabling any field, answer these 2 questions.

1. What will this data be used for, within the next month? If you can't name who will use it and for what, don't collect it yet. Data collected and never used is a maintenance obligation with no return.

2. If you don't ask at signup, can you get it elsewhere? Date of birth is a good example of something you have to ask for — no amount of purchase behaviour reveals it. What products someone likes, on the other hand, you don't need to ask: purchase history tells you.

💡 A rule that works for most businesses: make mandatory only what the system needs to serve the customer at all (name, contact number) and what's tied to a campaign you've already committed to (date of birth if you're running birthday offers; branch if you're measuring by location). Leave everything else optional.

Sign-up and login options

Customers can now sign up and log in with an email address as well as a phone number. Both are verified with a one-time password (OTP), so there is no password for the customer to set.

You choose under Registration & Login Method, at the top of the Register form setting card — the same page where you configure the form's fields. There are 3 options.

1. Phone number + OTP only How every brand worked until now: customers use a phone number only.

2. Email + OTP only Customers use an email address only. That address is also saved as their contact email, so the EMAIL bar is locked. If you still want a phone number to reach customers, turn on the CONTACT NO. bar instead.

3. Both — customer chooses Each customer picks a phone number or an email address and logs in with whichever they signed up with. If the same person signs up both ways, they end up with 2 separate accounts.

Click the option you want, then carry on with the steps below. It is saved together with the fields by the Save button in step 4. An email address or phone number a customer types into the form is contact information only — it can't be used to log in.

⚠️ One thing to watch when you switch: if the new option drops a channel your customers already use — say, from phone to Email + OTP only — a notice pops up to warn you. Acknowledge it to carry on; nothing changes until you click Save. Once saved, existing customers who signed up with a phone number can no longer log in until you change that customer's LOGIN KEY to an email address, under Account → Search / Detail. If you already have members, Both — customer chooses is the safest choice, because existing customers keep logging in as before.

Fixing an existing customer's login key

Use this when you've switched to Email + OTP only and have customers who signed up with a phone number. Fix them one at a time — you'll need each customer's email address, so ask them for it if you don't have it.

1. Find the customer Under Account → Search / Detail, type the customer's name or phone number and click the blue Search button.

2. Open the account detail page Click the blue person button in the Actions column of that customer's row.

3. Change LOGIN KEY to an email address It sits in the Identity & Contact section. Choose Email from the list in front of the box, type the customer's email address into the box next to it, then click Save Changes on the bar that appears at the bottom of the page.

The address must not belong to any other customer of the same brand. The EMAIL box further down is the contact email and does not change with it — update it too if you want the two to match.

Configure the form in 4 steps

Step 1: Open Register form Management

In the left sidebar, click Setting, then Register form Management.

The page lists every field on the registration form as a full-width bar. Scroll through the whole list from top to bottom — the field list isn't the same for every brand.
