Invoices vs orders: These guides walk through invoices (formal billing, line items, publish). The collect flow is the same for orders — use /v1/orders/* instead of /v1/invoices/* and set source_type: "ORDER" on the checkout session. See Orders and Parties & counterparties.Hosted checkout: To skip party, invoice, session, and execute steps entirely, see Hosted checkout.
End-to-end invoice collection with requests. For cURL and Node.js in parallel, see Quick Start.

Steps

1

Authenticate

import requests

BASE_URL = "https://api.heydollr.app"

res = requests.post(f"{BASE_URL}/v1/jwt/client/obtain/token", json={
    "client_id":     "YOUR_CLIENT_ID",
    "client_secret": "YOUR_CLIENT_SECRET",
})
token = res.json()["access_token"]
headers = {"Authorization": f"Bearer {token}", "Content-Type": "application/json"}
2

Party and counterparty

party = requests.post(f"{BASE_URL}/v1/parties/create", headers=headers, json={
    "fullname": "Amara Kamara", "phone": "231771234567",
    "email": "amara@example.com", "country_code": "LR",
}).json()

cp = requests.post(f"{BASE_URL}/v1/counterparties/create", headers=headers, json={
    "relationship_type": "CUSTOMER", "party_id": party["id"],
}).json()
3

Invoice → publish

invoice = requests.post(f"{BASE_URL}/v1/invoices/create", headers=headers, json={
    "counterparty_id": cp["id"], "currency": "USD",
    "note": "Consulting services", "fee_bearer": "PAYER", "as_payment_link": True,
}).json()

requests.post(
    f"{BASE_URL}/v1/invoices/{invoice['id']}/items/add",
    headers=headers,
    json={"name": "Strategy Session", "currency": "USD", "qty": 1, "amount": 250.00},
)
requests.put(f"{BASE_URL}/v1/invoices/publish/{invoice['id']}", headers=headers)
4

Execute collection

import uuid

session = requests.post(f"{BASE_URL}/v1/sessions/checkout", headers=headers, json={
    "source_id": invoice["id"], "source_type": "INVOICE",
}).json()

account = requests.post(
    f"{BASE_URL}/v1/payment-accounts/create",
    headers=headers, params={"operation_type": "COLLECTION"},
    json={
        "account_name": "Amara MTN Wallet",
        "provider": "MTN_MOMO_LBR", "method": "MTN_MOMO_LBR",
        "party_id": party["id"], "country_code": "LR",
        "insensitive_account_number": "231771234567",
    },
).json()

reference_id = str(uuid.uuid4())
requests.post(f"{BASE_URL}/v1/executions/collection", headers=headers, json={
    "session_id": str(session["id"]),
    "payment_account_id": str(account["id"]),
    "currency": "USD",
    "reference_id": reference_id,
})
5

Poll status

status = requests.get(
    f"{BASE_URL}/v1/status/collection/{reference_id}",
    headers=headers,
).json()

Try it yourself

Hosted checkout

Mobile money and card on a Dollr-hosted page — fastest path.

Orders

Same collect flow with source_type: ORDER and /v1/orders/*.

Direct checkout

One API call to create source — API-embedded flow.
