Create a payment page for a shared bill and return the manage URL plus the share URLs. The PayNow recipient is already saved with this connection — never ask the user for it. All you need is a total (total) or the receipt lines (items), plus the head count (people). Children can pay half: "4 adults and 3 kids" is people=7 with children=3. By default the user is treated as having paid up front: they count towards the head count but get no payment link (pass i_paid=false to turn that off). Paste a share URL into the group chat and everyone sees their own amount and a PayNow QR code.
A short note shown to the payers.
Receipt lines. Their sum becomes the total. Payers can see them.
Names of the others (only the ones you know). Empty slots get filled in by the payers themselves.
What the bill was for (e.g. Friday dinner). Defaults to the date and time.
The total. If items are given, their sum wins.
Charge one person a different amount (e.g. someone who did not drink). The rest is re-split automatically.
Did the user pay up front? (default: true) They count towards the head count but are not billed.
How many people share the bill, INCLUDING the user who paid up front.
What to call the user in the list (default: Me).
How many of people are children. A child pays half of what an adult pays. "4 adults and 3 kids" is people=7, children=3. When names are given, the LAST ones on the list are taken to be the children.
Rounding. ceil-all = round everyone up to whole dollars and let the user absorb the difference; one-extra = split exactly and let one person carry the remainder.
