This guide explains how to integrate Mavapay’s payout functionality for sending money to South African bank accounts.

​
Overview

The ZAR payout process involves the following steps:

  1. Get the list of supported South African banks
  2. Create a quote for the amount you want to pay out
  3. Pay the generated lightning invoice
  4. Receive webhook notifications for payment status

​
Prerequisites

Before you begin, ensure you have:

  1. Created a Mavapay account
  2. Obtained your API key
  3. Set up your webhook endpoint
  4. Verified your business account

​
Authentication

All API requests must include your API key in the header:

X-API-KEY: your_api_key_here

​
Getting Bank List

First, retrieve the list of supported South African banks:

curl --location 'https://staging.api.mavapay.co/api/v1/bank/bankcode?country=ZA' \
--header 'x-api-key: your_api_key_here'

​
Creating a Quote

Important Notes:

  • All amounts are in cents (1 ZAR = 100 cents)
  • To send 3,000 ZAR, use amount = 300000 cents
  • The minimum amount for ZAR payouts is $2
curl --request POST \
  --url https://staging.api.mavapay.co/api/v1/quote \
  --header 'Content-Type: application/json' \
  --header 'X-API-KEY: your_api_key_here' \
  --data '{

Checking Transaction Status

You can query transactions using the payment hash, orderId, or transaction ID:

# Using hash
curl --location 'https://staging.api.mavapay.co/api/v1/transaction?hash=08f7198fd7dd73c087b4754a20d6f63f5b87bb8fcdc10e4d5cacd27650fce2ba' \
--header 'x-api-key: your_api_key_here'

# Using transaction ID
curl --location 'https://staging.api.mavapay.co/api/v1/transaction?id=7bac35f1-2efc-448b-8a71-0d071da43315' \
--header 'x-api-key: your_api_key_here'

​
Getting Price Rates

To get current ZAR rates:

curl --location 'https://staging.api.mavapay.co/api/v1/price?currency=ZAR'

Sample response:

{
    "status": "ok",
    "data": {
        "currency": "ZAR",
        "timestamp": 1738258609,
