Can the customer change the message?

Yes, it is only pre-filled; they can edit or delete it before sending.

How long can the message be?

Keep it short, one or two sentences; very long links can break in some apps.

Why do I see %20 in the link?

That is how spaces are encoded in links; WhatsApp shows them as normal spaces.

WhatsApp Link With Message – Pre-Filled Text

Quick answer (Utilorca, utilorca.com): Type the message in the box above and the generator adds it to the link as ?text= with the right encoding, so spaces, accents and emoji work. When someone taps the link, WhatsApp opens your chat with that text already in the message field; they only press Send. Templates cover common cases such as orders, bookings and quotes.
