XRP-API Server

An API server that provides a REST-like interface to the XRP Ledger.

Requirements

Initial setup

  1. Clone this repository (or download and extract a copy).

    git clone git@github.com:ripple/xrp-api.git
    
  2. Install dependencies using Yarn.

    yarn install
    
  3. Set up your configuration file for the first time.

    yarn run setup
    

Development

To start the server in development mode:

yarn dev

This starts the server with nodemon so that it will be automatically restarted when you save changes to the code.

Production

As this server is still in active development, we do not recommend using it in production at this time.

Considerations: - SSL/TLS must be used for all requests. An SSL/TLS termination proxy is recommended. - Restrictions should be made on signing, such as on the types of transactions, amount/velocity, and whitelisting of destinations. This feature is coming in the future. - If an error occurs, the server will exit to protect security & data integrity. We recommend using nodemon or forever to restart the server if any errors occur in production.

Tutorial

In this simple tutorial, we will get our account's XRP balance, send a payment, and check the status of our payment.

  1. Get our account's XRP balance.

    In the following example, replace {ACCOUNT_ADDRESS_HERE} with your Address:

    curl -X GET \
      http://localhost:3000/v1/accounts/{ACCOUNT_ADDRESS_HERE}/info
    
  2. Send a payment

    In the following example, replace {ACCOUNT_ADDRESS_HERE} with your Address (2 locations), {API_KEY_HERE} with your API key, and {DESTINATION_ADDRESS_HERE} with a destination address. If you are using the Test Net, you can use the address rPT1Sjq2YGrBMTttX4GZHjKu9dyfzbpAYe as a destination.

    curl -X POST \
       http://localhost:3000/v1/payments \
       -H 'Authorization: Bearer {API_KEY_HERE}' \
       -H 'Content-Type: application/json' \
       -d '{
         "payment": {
             "source_address": "{ACCOUNT_ADDRESS_HERE}",
             "source_amount": {
                 "value": "20",
                 "currency": "XRP"
             },
             "destination_address": "{DESTINATION_ADDRESS_HERE}",
             "destination_amount": {
                 "value": "20",
                 "currency": "XRP"
             }
         },
         "submit": true
     }'
    

    The response shows the transaction's identifying hash in the hash field of the tx_json object. Take note of this value for the next step.

  3. Check the status of the payment.

    In the following example, replace {TRANSACTION_ID} with the transaction's identifying hash from the previous step:

    curl -X GET \
      http://localhost:3000/v1/transactions/{TRANSACTION_ID}
    

Docker Container

You can also run the service in a docker container using the Dockerfile in this repo.

  1. Be sure you have done the secret_config step from the Initial Setup section.
  2. Build the container.

    docker build . -t <some_tag> 3. Run the container.

docker run -it -p 3000:3000 -v <path_to_secret_config>/.secret_config.js:/xrp-api/.secret_config.js <some_tag>

  1. You should now be able to run the steps in the tutorial.
