Server-Side

With all the information collected in the backend, send a POST with the necessary attributes to the endpoint /v1/payments and execute the request or, if you prefer, send the information using our SDKs.

Important
When executing the APIs mentioned in this documentation, you may come across the attribute X-Idempotency-Key. Filling it out is important to ensure the execution and reexecution of requests without undesirable situations, such as duplicate payments, for example.

The onSubmit callback contains all the necessary data for a payment creation, however, if you wish, it is possible to include additional details, which can facilitate the purchase recognition by the payer, and increase the payment approval rate.

To do that, add the relevant fields to the recieved object, contained in the Brick's onSubmit callback. Some of these fields are: description (this field can be shown in created tickets) and external_reference (id of the purchase in your website, which eases the purchase recognition for the buyer). It is also possible to add complementary buyer's data.

Important
We recommend adherence to the 3DS 2.0 protocol, in order to increase the probability of approval of your payments, which can be done as described here.

Check API References to learn about all the available fields for full payments.
