Important: From December 1, 2026, this endpoint will be deprecated; we advise you to move to our new Online Onboarding system, which is faster and more effective. Contact your account manager or support for information.

Enables your system to create a legal payment account by following these steps:

1. Your client enters their personal data on your platform (e.g. in their profile).
2. Your server calls the Accounts API.
3. Lemonway provisions the payment account in your environment.
4. Your system reads the API response and notifies the user.

The API enforces several validation rules:

• Injection checks
  • String parameters (email, name, etc.) must not contain unusual or non‑standard characters.

• Name requirements (first & last name)
  • Cannot be a placeholder or “made‑up” value (e.g. “name”, “nom”, “prenom”, “test”, “unknown”).
  • Must consist of at least two characters and include at least one vowel.
  • First name and last name must differ.
  • No character may repeat three times in a row.
  • Additional checks may apply for special cases (e.g. VIP or politically exposed persons).

Important: Whenever you see accountId in a path or body parameter, enter your wallet’s ID.
