XRP API Server
An API server that provides a REST-like interface to the XRP Ledger.
➡️ XRP API Reference Documentation
See the full reference documentation on the XRP Ledger Dev Portal.
Building with TypeScript, JavaScript, or Node.js?
Instead of XRP API, you can use ripple-lib for a native integration experience and access to more advanced XRP Ledger features.
Requirements
-
An XRP Ledger account with XRP
For development, you can use the XRP Testnet and get some test XRP from the XRP Testnet Faucet. The setup script will do this for you automatically.
Initial setup
-
Clone this repository (or download and extract a copy).
git clone git@github.com:xpring-eng/xrp-api.git
Change directory into the project.
cd xrp-api
-
Install dependencies using Yarn.
yarn install
-
Set up your configuration file for the first time.
yarn run setup
For testing and development, you can use the XRP Faucets. At this time, the following public servers are available:
-
Testnet:
wss://s.altnet.rippletest.net:51233
-
Devnet:
wss://s.devnet.rippletest.net:51233
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.
The default port is 3000. To use a custom port, use yarn dev <port>
. Example:
yarn dev 3001
Production
If you would like to use xrp-api in production with real funds, please contact us! We will assist with your secure deployment.
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 PM2, nodemon, or forever to restart the server if it crashes 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.
-
Get our account's XRP balance.
In the following example, replace
{ACCOUNT_ADDRESS_HERE}
with your Address:curl -X GET \ http://localhost:3000/v3/accounts/{ACCOUNT_ADDRESS_HERE}/info
-
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 Testnet, you can use the addressrPT1Sjq2YGrBMTttX4GZHjKu9dyfzbpAYe
as a destination.curl -X POST \ http://localhost:3000/v3/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 thetx_json
object. Take note of this value for the next step. -
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/v3/transactions/{TRANSACTION_ID}
Docker Container
You can also run the service in a docker container using the Dockerfile in this repo.
-
Be sure you have done the secret_config step from the Initial Setup section.
-
Build the container.
docker build . -t <some_tag>
-
Run the container.
docker run -it -p 3000:3000 -v $PWD/.secret_config.js:/xrp-api/.secret_config.js <some_tag>
-
You should now be able to run the steps in the tutorial.
Debugging
- We use log4js with 7-character category names and a shim that uses the
NODE_DEBUG
environment variable to enable logging of specific categories. - Example:
NODE_DEBUG=prp/pmt node dev
- Available categories:
prp/pmt
: GET /v3/preparations/payments (./src/api-v3/paths/preparations/payments.ts)
- During development, add logging by using the built-in log levels
Notes
- Requires Node.js 10.4.0+ for
BigInt
support.
