Intent and Bundle Parameters

This reference documents the Intent action strings and Bundle parameter specifications used for App2App integration with the Get Mini application. All parameters must be passed as Intent extras using the putExtra() method.

This reference applies to App2App integration only. If you’re using direct SDK integration, refer to the SDK Methods Reference instead.

Intent Actions

To initiate a transaction or query request, your application must create an Intent with one of the following action strings.

Operation Type	Action String
Payment Transaction	`es.redsys.paysys.mPOSRedsys_PAYMENT_REQUEST`
Query Operation	`es.redsys.paysys.mPOSRedsys_QUERY_REQUEST`
Refund Transaction	`es.redsys.paysys.mPOSRedsys_REFUND_REQUEST`

Each Intent action handles a specific operation type. The Get Mini application processes the input and returns results via the onActivityResult callback.

Request Parameters

Add these parameters to your Intent using putExtra() before launching the Get Mini application. All keys are case-sensitive and must match exactly.

Payment Parameters (PAYMENT_REQUEST)

Extra Key	Type	Required	Description
`amount`	double	Yes	The total amount to charge (e.g., 25.50).
`invoice`	String	No	Order number or identifier.

Query Parameters (QUERY_REQUEST)

Extra Key	Type	Required	Description
`dateFrom`	String	Yes	Start date of the query range.
`dateUntil`	String	Yes	End date of the query range.

Refund Parameters (REFUND_REQUEST)

Extra Key	Type	Required	Description
`amount`	double	Yes	The amount to be refunded.
`date`	String	Yes	Date of original payment in YYYYMMDD format.
`authorization`	String	Yes	Authorization number from original transaction.
`order`	String	Yes	Order number ID from original transaction.

Response Parameters

The result Intent contains transaction details stored as extras. Use getStringExtra() or getIntExtra() to retrieve them.

Extra Key	Type	Always Present	Description
`STATE`	String	Yes	Result code of the operation. On a declined operation it carries the denial code.
`ERROR_MSG`	String	No	Human-readable explanation of error or denial.
`ORDER`	String	No	Unique order number assigned by the system.
`AUTORIZATION_NUMBER`	String	No	Host authorization code (Note: missing ‘H’ in the key).
`IDENTIFIER_RTS`	String	No	SDK internal reference ID (24 positions).

Parameter Access Notes

Authorization Key: The key is literally "AUTORIZATION_NUMBER". Documentation must reflect this exact spelling.
Receipts: On Android Q and above, use intent.getData() to retrieve the receipt URI. For older versions, use the TICKET_IMAGE extra.

Activity Result Codes

The Android result code indicates if the Get Mini app completed its workflow.

Result Code	Constant	Meaning
-1	`RESULT_OK`	Flow completed. Check `STATE` or `RESULT` for outcome.
0	`RESULT_CANCELED`	User exited or app failed to initialize flow.
