Which parameter should be set when creating an account link for onboarding?

When creating an account link for onboarding, setting the parameter to "account_onboarding" is essential as it specifically designates the purpose of the link in the Stripe API. This parameter ensures that the link generated is tailored for user onboarding, guiding new account holders through the necessary steps to set up their accounts with Stripe.

Onboarding typically involves collecting relevant information from the user, such as personal details, business information, and banking details, which are critical for establishing a functional Stripe account. By specifying "account_onboarding," you indicate explicitly that this link is part of that process, ensuring that the user experiences a flow that is optimized for onboarding rather than any other function.

The other parameters mentioned serve different purposes. "Account_creation," for instance, might be misinterpreted as signifying the act of simply creating an account without the context of onboarding, which requires further action and input from the user. "User_verification" would focus more on confirming the user’s identity rather than facilitating the onboarding experience. Lastly, "transaction_confirmation" deals with confirming individual transactions rather than the overarching account setup process. Thus, selecting "account_onboarding" aligns directly with the goal of seamlessly integrating new users into the Stripe ecosystem.
