Collecting & validating input

Ask a question, validate the answer, and save it to a variable.

To capture something from the user, use the Ask and save block. It sends a question, waits for the reply, validates it, and stores it in a variable.

How it works

1. The block sends your question and pauses the flow (⏸).
2. The user replies.
3. The reply is validated against the chosen input type.
4. On success it’s saved to your variable and the flow follows the ok arrow; on failure it follows invalid.

Input types

text, number, email, phone, photo, geo (location). Each enforces a basic format so you don’t store garbage.

Ask "How old are you?"  type: number  →  var: age
 ├─ ok      → Condition {{var.age}} >= 18
 └─ invalid → "Please send a number"

The saved value is now a normal variable — use {{var.age}} anywhere.
