import asyncio
from decimal import Decimal
from robokassa import create_invoice, RobokassaClient
# Build a signed checkout URL (no HTTP โ just URL construction).

Full refund flow
from robokassa import RobokassaClient
async def refund_flow(inv_id: int) -> None:
async with RobokassaClient("my-shop", password2="p2", password3="p3") as client:
# 1. Fetch the payment state to get its OpKey.
state = await client.check_payment(inv_id)
assert state.info.op_key, "payment not complete yet"
# 2. Initiate a refund.
created = await client.refund_create(state.info.op_key)
print("refund requestId:", created.request_id)
# 3. Poll status until finished / canceled.
while True:
status = await client.refund_status(created.request_id)

Webhook signature verification (FastAPI example)
from fastapi import FastAPI, Request, HTTPException, PlainTextResponse
from robokassa import verify_result_signature, build_ok_response
app = FastAPI()
@app.post("/robokassa/result")
async def result_url(req: Request) -> PlainTextResponse:
form = dict(await req.form())
if not verify_result_signature(form, password2="..."):
raise HTTPException(status_code=403, detail="Bad signature")
# ... persist the notification, mark invoice paid ...
return PlainTextResponse(build_ok_response(form["InvId"]))

MCP tools exposed to agents
All 18 tools are wrapped as @mcp.tool() and available to any MCP-capable agent (Claude Desktop, Claude Code, Cursor, Windsurf, etc.).
| Tool | Purpose | Auth |
|---|---|---|
create_invoice | Build a signed checkout URL (optional 54-ะคะ receipt). | Password#1 |
check_payment | Get current state of a payment by InvId (via OpStateExt). | Password#2 |
list_currencies | List payment methods available to the shop. | โ |
calc_out_sum | Compute amount credited to shop for a given payment. | Password#1 |
refund_create | Initiate a refund (requires Refund API access). | Password#3 JWT |
refund_status | Poll refund progress by requestId. | โ |
verify_result_signature | Validate a ResultURL webhook. | Password#2 |
verify_success_signature | Validate a SuccessURL redirect. | Password#1 |
hold_init / hold_confirm / hold_cancel | Two-step card pre-authorization. | Password#1 |
init_recurring_parent / recurring_charge | Subscription auto-charges. | Password#1 |
build_split_invoice | Marketplace multi-recipient checkout. | โ |
send_sms | Paid SMS service. | Password#1 |
second_receipt_create / second_receipt_status | 54-ะคะ final receipt after advance. | Password#1 |
partner_refund | Alternative refund path for partner integrators. | Partner JWT |
Low-level signature helpers are available from Python only: compute_signature, op_state_signature, build_checkout_signature, build_refund_jwt, build_sms_signature, compute_result_signature, compute_success_signature, encode_fiscal_body.
API coverage
Mapped against the 8 public Robokassa API groups:
| Group | Coverage | Module |
|---|---|---|
| Merchant Checkout | โ
create_invoice (+ 54-ะคะ) | robokassa.checkout |
| XML Interfaces | โ
check_payment, list_currencies, calc_out_sum | robokassa.xml_interface |
| Refund API | โ
refund_create, refund_status | robokassa.refund |
| Holding / Pre-auth | โ init / confirm / cancel | robokassa.holding |
| Recurring | โ parent + child | robokassa.recurring |
| Fiscal 54-ะคะ | โ second receipt create / status | robokassa.fiscal |
| Partner API | ๐ก partner_refund only โ see coverage notes | robokassa.partner |
| Auxiliary | โ
send_sms, webhook signatures, split payments | robokassa.sms, robokassa.webhooks, robokassa.split |
Environment variables
Most high-level entry points fall back to these env vars when credentials aren't passed explicitly:
| Variable | Required for |
|---|---|
ROBOKASSA_LOGIN | All operations |
ROBOKASSA_PASSWORD1 | Checkout, webhook SuccessURL verification, CalcOutSumm, fiscal, SMS |
ROBOKASSA_PASSWORD2 | check_payment (OpStateExt), webhook ResultURL verification |
ROBOKASSA_PASSWORD3 | refund_create |
Signature algorithms
All signature-producing helpers accept algorithm= with "md5" / "sha256" / "sha384" / "sha512" โ match whatever is configured in your Robokassa cabinet.
