Merchant-initiated payments

Under PSD2, it is permitted to charge a customer without him being present, provided that he has explicitly accepted it..

The process to make this type of collection is as follows:

• A secure first payment must be made, also indicating what type of payments will be made to the client later. To do this, the "trxType" parameter must be included with one of the values indicated in this table:
  
  
  

  Value	Concept
  I	Deferred payment. Always refers to an INDIVIDUAL purchase, the amount of the different transactions being set, and with a defined time period
  R	Recurring payment. The amount of the transactions may be set or variable, and with a defined time period
  H	Normally due to partial deliveries. Also, when the client extends the hotel stay / vehicle rental or when there is an estimated authorisation, the final amount is requested (“conclusion”)
  E	Original rejected due to “balance”; only for certain activity sectors (for greater detail review the brand requirements) and with a maximum number of days since the purchase. Relevant example: “Transport”
  D	Those which occur following the operation for services provided / used, unknown at the beginning. (Minibar, vehicle damage, fines, etc.)
  M	When additional services are incurred during the contract period
  N	When the business charges for services which the holder committed to, but then did not comply with the agreed terms. Relevant example: no-show hotel reservations without cancellation.
  C	Other

  If the merchant is going to launch subsequent collections, "trxType" = "R" or "I", the duration of the recurrence and the collection period must also be indicated in the "merchantData" parameter:

  
  {
  	"recurringExpiry": "",
  	"recurringFrequency": "",
  }
              
          

  Element	Content	Description
  recurringExpiry	[0-9]{8}	Conditional. Mandatory for Recurring and Instalment operations ("trxType" = I or R). The date from which there will be no more authorisations. Accepted format: YYYYMMDD
  recurringFrequency	[A-Za-z0-9]{1,4}	Conditional. Mandatory for Recurring and Instalment operations ("trxType" = I or R). Indicates the minimum number of days between authorisations

• Subsequent payments in which the customer is not present must indicate the parameter "scaException" with the value "MIT" and the field "trxType" with the value that was indicated in the first payment.
  If the initial payment was with "trxType" = "R" or "I", the fields "recurringExpiry" and "recurringFrecuency" must always be sent.
