Notice: For security reasons, the 1cs Online Payment System rejects all payment requests with formatting errors. Therefore, please use the correct data type for each parameter.
The following table describes the encrypted payment request parameters:
| Key | Format | CND | Description |
|---|---|---|---|
| MerchantID | ans..30 | M | MerchantID, assigned by First Cash Solution. Additionally this parameter has to be passed in plain language too. |
| TransID | ans..64 | M | TransactionID provided by you which should be unique for each payment |
| RefNr | ans..40 | O | Merchant’s unique reference number. Only characters a-zA-Z0-9,-_ are allowed. |
| Amount | n..10 | M | Amount in the smallest currency unit (e.g. EUR Cent). Please contact the 1cs Support, if you want to capture amounts <100 (smallest currency unit). |

| MAC | an64 | M | Hash Message Authentication Code (HMAC) with SHA-256 algorithm. Details can be found here: HMAC Authentication (Request) HMAC Authentication (Notify) |
| OrderDesc | ans..768 | M | Description of goods and prices. Intended purpose on the statement of account. |
| URLSuccess | ans..256 | M | Complete URL which calls up 1cs Online Payment System if payment has been successful. The URL may be called up only via port 443. This URL may not contain parameters: In order to exchange values between 1cs Online Payment Systemand shop, please use the parameter UserData. Common notes: We recommend to use parameter “response=encrypt” to get an encrypted response by 1cs OPS. However, fraudster may just copy the encrypted DATA-element which are sent to URLFailure and send the DATA to URLSuccess. Therefore ensure to check the “code”-value which indicates success/failure of the action. Only a result of “code=00000000” should be considered successful. |
| URLFailure | ans..256 | M | Complete URL which calls up 1cs Online Payment System if payment has been unsuccessful. The URL may not be called up only via port 443. In order to exchange values between 1cs OPS and shop, please use the parameter User Data. Common notes: We recommend to use parameter “response=encrypt” to get an encrypted response by 1cs OPS. However, fraudster may just copy the encrypted DATA-element which are sent to URLFailure and send the DATA to URLSuccess/URLNotify. Therefore ensure to check the “code”-value which indicates success/failure of the action. Only a result of “code=00000000” should be considered successful. |
| Response | a7 | O | Status response sent by 1cs OPS to URLSuccess and URLFailure, should be encrypted. For this purpose, transmit Response=encrypt parameter. |
| URLNotify | ans..256 | M | Complete URL which 1cs OPS calls up in order to notify the shop about the payment result. The URL may be called up only via port 443. It may not contain parameters: Use the UserData parameter instead. Common notes: We recommend to use parameter “response=encrypt” to get an encrypted response by 1cs OPS. However, fraudster may just copy the encrypted DATA-element which are sent to URLFailure and send the DATA to URLSuccess/URLNotify. Therefore ensure to check the “code”-value which indicates success/failure of the action. Only a result of “code=00000000” should be considered successful. |
| UserData | ans..1024 | O | If specified at request, 1cs OPS forwards the parameter with the payment result to the shop. |
| ReqId | ans..32 | O | To avoid double payments or actions (e.g. by ETM), enter an alphanumeric value which identifies your transaction and may be assigned only once. If the transaction or action is submitted again with the same ReqID, 1cs Online Payment System will not carry out the payment or new action, but will just return the status of the original transaction or action. Please note that the 1cs OPS must have a finalized transaction status for the first initial action (authentication/authorisation). This does not apply to 3-D Secure authentications that are terminated by a timeout. The 3-D Secure Timeout status does not count as a completed status in which the ReqID functionality on 1cs OPS does not take effect. Submissions with identical ReqID for an open status will be processed regularly. Notice: Please note that a ReqID is only valid for 12 month, then it gets deleted at the 1cs OPS. |
| SellingPoint | ans..50 | O | Selling point |
| Service | ans..50 | O | products or service sold |

| Plain | ans..50 | O | A single value to be set by the merchant to return some information unencrypted in response/notify, e.g. the MID. “Plain”-parameter is part of encrypted “Data” in 1cs OPS and therefore protected against manipulation. |
| Custom | ans..1024 | O | “Custom”-parameter is added to the request data before encryption and is part of encrypted “Data” in 1cs OPS request. By this they are protected against manipulation by a consumer. The Custom-value is added to the 1cs OPS response in plain text and the “|” is replaced by a “&”. By this you can put a single value into Custom-parameter and get multiple key-value-pairs back in response for your own purpose. Please find a samples here: Custom |
