Stripe Payment Intent ID

Validation

Validates a Stripe Payment Intent ID (pi_XXXXXXXX...).

/^pi_[A-Za-z0-9]{24,32}$/

How it works

Payment Intents are the modern Stripe charging primitive. The pi_ prefix distinguishes them from older ch_ charges. Use both regexes in a webhook handler that supports both flows.
