Start integrating Klavi payment
Step 1: Authentication
Before request the Klavi payment API, you must first obtain a JWT bearer token by request the auth, once you have a JWT bearer token you can submit requests on protected APIs like participants and payments.
Curl request example:
Curl
curl --location --request POST 'https://api-testing.klavi.ai/payment/customer/v1/auth' \
--header 'Content-Type: application/json' \
--data-raw '{
    "accessKey": "k0l1l2v3i4",
    "secretKey": "TtMdrH&a8Mjd9FyULnFs*#dypaX15%qpXtXQt2n$"
}'
curl --location --request POST 'https://api-testing.klavi.ai/payment/customer/v1/auth' \
--header 'Content-Type: application/json' \
--data-raw '{
    "accessKey": "k0l1l2v3i4",
    "secretKey": "TtMdrH&a8Mjd9FyULnFs*#dypaX15%qpXtXQt2n$"
}'

	"expire": "2023-02-16T17:16:30.189341+08:00"
}

Step 2: List Account Providers​﻿
Now that you have an access token, you can display the list of account providers participating in Open Finance to users. After the user selects his account holding institution, all you need to do is save the id for later use on the payments API.
Curl request example:
Curl
curl -L -X GET 'https://api-testing.klavi.ai/payment/customer/v1/participants' \
--header 'Content-Type: application/json' \
--header 'Accept: application/json' \
--header 'Authorization: Bearer 6IkpXVCJ9.eyJwYWdhdGV3YXkifQ.FKX8rT3jIFfeOLYTgTrzlSbOjMIMPAZipkH4VdhL-NB'
curl -L -X GET 'https://api-testing.klavi.ai/payment/customer/v1/participants' \
--header 'Content-Type: application/json' \
--header 'Accept: application/json' \
--header 'Authorization: Bearer 6IkpXVCJ9.eyJwYWdhdGV3YXkifQ.FKX8rT3jIFfeOLYTgTrzlSbOjMIMPAZipkH4VdhL-NB'

Step 3: Send payment payload
Now that you have a JWT access token and the participantId that the end-user selected, it's time to show the checkout and to get the user confirmation on the payment transaction. Once confirmed, you need to send the payload of the payment to be enqueued and then processed. The example below displays the minimum payload information required:
