}Payment methods
Create a payment method
Enrolls a Mexican direct debit mandate and returns the payment method that represents the mandate. Send the request as multipart/form-data, with the mandate fields and the four documents under mx_direct_debit[consent_documents] in the same request. Fintoc registers the mandate with the account’s bank and returns the payment method with its mx_direct_debit status set to pending. The account holder authorizes the mandate with their bank. The request is atomic. If a document is invalid, Fintoc creates nothing and returns a 422 Unprocessable Entity error. A document is invalid if it is outside the 100 bytes to 10 MB range, or is not a PDF, JPEG, or PNG.
