/v1/onboarding-sessions

Returns a single-use onboarding link to display within your product. The business confirms its tax ID, links a bank account and signs the agreement.

Call from your server when a business requests early payment. Send the link only to that business.
Links are single use and expire after 15 minutes. Create a new link as needed, including after a page reload.

Not yet live. Links created today do not resolve. Build against the current shape. Lunch will announce availability.
