Rapyd API Headers Kotlin Library

Overview

The rapyd-api-headers library provides functionality for generating headers required for Rapyd API requests. It includes methods for creating HMAC SHA-256 signatures and other necessary headers. This library was developed based on the official Rapyd documentation. It provides a streamlined way to generate headers and manage requests when integrating with the Rapyd API, helping developers interact with Rapyd's powerful global payment platform more efficiently.

IMPORTANT: Never share your access key and secret key publicly or with unauthorized personnel. Additionally, avoid enabling debug logging in production environments, as it may expose sensitive information.

Features

• Generate API Headers: Automatically generate the headers required for Rapyd API calls, including the HMAC signature, salt, and timestamp.
• Support for Various HTTP Methods: Handles different HTTP methods (GET, POST, etc.).
• Customizable: Allows customization of request bodies and paths, and enables overriding the default JSON ObjectMapper.

Compatibility

This library requires Java 17 or higher.

Kotlin

import com.fasterxml.jackson.databind.ObjectMapper
import com.smelman.rapyd.api.headers.service.HeadersServiceImpl

fun main() {
    val accessKey = "your_access_key"
    val secretKey = "your_secret_key"

    val headersService = HeadersServiceImpl(accessKey, secretKey)

    // Example for GET request without body
    val headers = headersService.generateRapydHeaders(
        httpMethod = "GET",
        path = "/v1/data/countries"
    )

    println(headers.toString())

    // Example for POST request with body
    val requestBody = mapOf("key" to "exampleKey", "value" to "exampleValue")
    val headersWithBody = headersService.generateRapydHeaders(
        httpMethod = "POST",
        path = "/v1/data/countries",
        body = requestBody
    )

    println(headersWithBody.toString())
}
