Headers

​
If-Unmodified-Since

The session ID

Body

mobile number of a person / company, ITU/E.123 format with international prefix (+PPNNNNNNNNN...)

​

​
actions
object[]
required
​
redirect_url
string

redirect url to complete payment, will not be included if the payment failed with Rejected error as payment can be completed by choosing alternative payment option.

​
poll_url
string

poll_url to check the status of the payment. Will be included if the payment is dependent on 3rd party apps, such as Swish.

​
approval_url
string

approval_url to complete the payment in a different app from the one showing the checkout, eg. an app link for the Swish M-Commerce flow. Should be used in conjunction with the poll_url to check the status of the payment.

​
qr_code
string

A base 64 encoded image of the QR code can be displayed while the checkout frontend is polling for the payment status. Eg. used as a fallback for the Swish M-Commerce flow if we are unable to open the approval_url on the end users device we can display the QR code and the user can scan it using a different device that has the app used for payment installed.

By default the image has a size of 600 x 600 pixels.

Example:

"data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAYAAAAf8/9hAAABzklEQVR42mNkAAYy..."

​
error
string
Example:

"Rejected"
