Self-service onboarding

You only apply once. Sandbox access is granted the moment you submit. Production access uses the same application, plus a manual KYB review that's handled separately.

Apply

API shape

The form above posts to the same endpoint as the samples below. If you're an issuer, include your capability profile fields so your sandbox setup matches what you'll run in production.
