key must be provided for either the factory function or .pay.
The callback is called in "node-style": callback(error, response).
The response will look like this:
{
transaction: {
id: String,
},
custom: { ... },
}If the user closes the popup the error variable will have a value of closed.
If another popup is opened in the meantime error variable will have a value of
superseded.
All supported currencies are listed at https://github.com/paylike/currencies.
The field is optional. If none is provided, the merchant's "descriptor" is used.
The maximum length is 1024 characters. For payment cards (such as Visa,
Mastercard, etc.) the length must be at least 2 characters, it will be truncated
to 22 characters, and only characters matching /[\x20-\x7E]/ are accepted
(others are replaced).
The text is forwarded to be shown on the customer's bank statement or similar. There is no guarantee as to how the issuer of the customer's payment instrument (e.g. their bank) will use or show this text.

)If you add a field with a name of "amount" it will allow users to dynamically choose the transaction amount. See this example.
The test parameter may be used to trigger specific payment flows and
scenarios. The format is described in
the API reference documentation for the payments API.
To reuse a card for later transactions from your server, specify at least one of
plan and unplanned.
You can omit amount entirely if no amount is due immedately, but it can
validly be combined with plan and unplanned for a purchase.
Later on create a transaction from your server using our API: create a transaction using a previous transaction.
Make sure to read our section about recurring payments.
Please see this document.
This is required for planned subsequent payments to ensure compliance and high approval rates.
{
plan: [
{
amount: {currency: 'EUR', value: 999, exponent: 2},
repeat: {
interval: {unit: 'month'},
},
}
],
}A monthly subscription of EUR 9.99.
Flag the types (one or more) of unplanned payments the card could be used for in the future. The supported types are:
customer(initiated by the customer from your website/application)merchant(initiated by the merchant or an off-site customer)
This is required for unplanned subsequent payments to ensure compliance and high approval rates.
You wish to automatically charge the card for each ride in a roller coaster:
{
// ...
unplanned: {merchant: true},
}You allow customers to save their card for faster checkout in the future:
{
// ...
unplanned: {customer: true},
}The difference between the two scenarios is whether the customer is triggering the purchase from a device capable of authenticating the payment.

In the payments API reference you can find the relevant details for submitting payments.
The SDK is tested in all regular browsers capable of conducting modern secure communication as required for payments.
