Merchants must complete onboarding themselves so they can accept Dintero’s terms of service. There are two flows for creating new merchants under your partner account. Both accept an optional signup_reference parameter that you can use to track which invitation a merchant signed up from. You can retrieve this value later from the applicant.signup_reference field when you get the account settings.

​
Alternative 1: Self-service onboarding

You link the merchant to the Dintero onboarding form. The merchant submits their details, accepts the terms of service, verifies their email address, and creates a password for their Dintero account. 
https://onboarding.dintero.com/?partner={partner_id}&signup_reference={signup_reference}
Example: https://onboarding.dintero.com/?partner=112&signup_reference=abc-123

​
Alternative 2: Prefilled onboarding

You prefill the merchant’s details using the prefill form. The merchant receives an email with a link to review and edit their details, accept the terms of service, and create a password. 
https://onboarding.dintero.com/prefill?partner={partner_id}&signup_reference={signup_reference}
Example: https://onboarding.dintero.com/prefill?partner=112&signup_reference=abc-123
