The birthday card

This page opens on the Party design — bunting along the top, balloons in the corners — in a sunny yellow with rounded, playful lettering. It starts with “You're invited to” above the big line and “Come and celebrate with us” below. Put the occasion in the big line: “Riya's 5th Birthday”, “Arjun turns 30”, “Amma's 60th”.

For a child's party

• Give an end time. Parents need to know when to come back. Fill in “Ends” and the card shows both times; the calendar entry a guest saves runs to the same time.
• Ask for a reply with a number. Put your name and phone number under “Replies go to”. The reply a guest sends says how many of them are coming, which is the number you need for the cake, the return gifts and the party hall.
• Use the note for what does not belong on a card: “Siblings welcome”, “Please tell us about any food allergy”, “Bring a swimsuit and a towel”, “No gifts, please”.
• Paste a map link if the party is at a play zone inside a mall or a hall up a side road. Without one, the guest's “Open map” button searches for the venue name and address you typed.

For a grown-up's birthday

The same card looks different in a tap or two. Sparkle in navy and gold suits a 30th or a 50th; Classic in maroon and gold a 60th or a shashtipoorthi; Modern for dinner at a restaurant. Change the lettering to Elegant or Script and the opening line to “Please join us to celebrate”.

A surprise party

Say so on the card, where nobody can miss it: make the line under the title “It's a surprise — please don't tell her!” and put the time guests must arrive by in the note, earlier than the time on the card if you need them hidden first. Send the link person by person, not in a group the birthday person is in.

Sending it to the class

For a class party the usual way is the parents' WhatsApp group: tap “Share the card picture” to post the card itself with the message under it, so everyone sees the invitation without opening anything, and those who open the link get the map, the calendar button and the reply buttons. If only some of the class are invited, send each family their own message instead.
