Create an invoice

Receive funds from the testnet faucet

Setup Your Wallet in Testnet Mode

We're going to use testnet so that no real funds need to be used. The easiest way to do this is to clone the payd repo and run a make command which sets the wallet up with BA hosted DPP Proxy to make this as simple as possible. Run this bash script in your terminal to get set up:
git clone
cd payd
make run-compose-faucet
Once that's all up and running you can test out a basic endpoint to check things are operational in a different terminal window:
curl --request GET \
--url http://localhost:8443/api/v1/balance
The response should be:
{ "satoshis":0 }
You can then create an invoice for 1,000 testnet satoshis.
curl --request POST \
--url http://localhost:8443/api/v1/invoices \
--header 'Content-Type: application/json' \
--data '{
"satoshis": 1000
You will get a response like:
"id": "3gJA9rq",
"reference": null,
"description": null,
"satoshis": 1000,
"expiresAt": "2022-08-23T14:18:05.6993126Z",
"paymentReceivedAt": null,
"refundTo": null,
"refundedAt": null,
"state": "pending",
"createdAt": "2022-08-22T14:18:05.6993126Z",
"updatedAt": "2022-08-22T14:18:05Z",
"deletedAt": null
The only important part at this stage is the id. This will form the part of the URL for requesting payment from the faucet, so you should copy it and paste it into a URL of this format:{id}

Receive Funds

Go to DPP testnet faucet and paste the above payment url with your invoiceId into the payToUrl text input, then hit that pay to url button.
Should look something like this
Your balance should have updated by 1000 sats, which you can check by hitting the balance endpoint in browser: http://localhost:8443/api/v1/balance ; or using the curl command:
curl --request GET \
--url http://localhost:8443/api/v1/balance
Requests are limited to 100,000 satoshis max, which should be plenty to test out your applications and learn more about the Lite Client Toolbox modules.
