Starts with?
Text
Result
Prefix
Description
Pure function returning true if text starts with prefix.
When to use
Use Starts with? when the meaningful condition is anchored at the beginning of a string — for example, checking that a URL starts with “https://” or that a reference number starts with a required prefix. The check is case-sensitive; apply Lowercase first for a case-insensitive variant.
Pins
Input pins
| Pin | Type | Default | Notes |
|---|---|---|---|
| Text | string | — | The string to test. The check is case-sensitive. |
| Prefix | string | — | The literal prefix to look for at the start. An empty prefix always matches. |
Output pins
| Pin | Type | Notes |
|---|---|---|
| Result | boolean | True if the first characters of text match prefix exactly; false otherwise. |
Example
Ensure a webhook URL uses HTTPS before making an outbound call. Wire the URL into the
Text input of Starts with? with Prefix set to "https://", then connect the Result
output to the Condition input of Branch. The False execution output routes to Fail with
an “HTTPS required” message before the HTTP request is ever attempted.
