Starts with?

Strings Pure
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.
