absolutepay 0.3.0

Official AbsolutePay API client for Python — payments, payouts, invoices, conversions, off-ramp, gift cards, and signed webhooks.

absolutepay

Official AbsolutePay API client for Python. Server-side only — your API key and signing secret must never reach a browser.

Every request from an app key is HMAC-signed automatically. Inbound webhooks are verified with one call. Zero runtime dependencies — standard library only.

Install

pip install absolutepay

Requires Python 3.9+.

Environments

Config	Base URL
default	https://api.absolutepay.io (production)
sandbox=True	https://sandbox-api.absolutepay.io
base_url="https://…"	your override (takes precedence over sandbox)

Use a dedicated sandbox app (sign up at sandbox.absolutepay.io) with sandbox=True to test end-to-end without moving real funds.

Quickstart

import os
from absolutepay import AbsolutePay

ap = AbsolutePay(
    api_key=os.environ["ABSOLUTEPAY_API_KEY"],            # ap_live_… / ap_test_…
    signing_secret=os.environ["ABSOLUTEPAY_SIGNING_SECRET"],  # apisign_…  (required for app keys)
    # sandbox=True,             # → https://sandbox-api.absolutepay.io (default is production)
    # base_url="https://…",     # optional: override the origin entirely (wins over sandbox)
)

balances = ap.balances.list()
preview = ap.fees.preview(amount="100", currency="USDT")

invoice = ap.invoices.create(
    reference="order-123",
    amount={"amount": "25.00", "currency": "USDT"},
    chain="MATIC",  # mint the deposit address up front; omit to let the payer pick
    redirect_url="https://shop.example.com/thank-you",  # payer returns here when done
)
print(invoice["token"])

Money

Amounts are plain dicts — a decimal string plus a currency code:

{"amount": "10.00", "currency": "USDT"}

Resources

balances · fees · payouts · refunds · conversions · invoices (+ invoices.public) · subscriptions · giftcards · offramp · transactions

# Hosted checkout link — the payer picks which asset/chain to pay with
checkout = ap.invoices.create_checkout(
    reference="order-123",
    amount={"amount": "25.00", "currency": "USDT"},
)
print(checkout["checkoutUrl"])  # send the payer here; confirm via the payment.succeeded webhook

# Batch payout (idempotent — a retry with the same key never pays twice)
ap.payouts.create(
    [{"recipientAddress": "0xabc…", "chain": "MATIC", "amount": {"amount": "5.00", "currency": "USDT"}}],
    idempotency_key="payroll-2026-07-01",
)

# Quote + execute a conversion in one call
order = ap.conversions.convert(sell_currency="USDT", buy_currency="ETH", sell_amount="100")

# Ledger, filtered by time range (epoch ms) and paginated
ledger = ap.transactions.list(from_=1_700_000_000_000, to=1_800_000_000_000, limit=50, offset=0)

Errors

Non-2xx responses raise AbsolutePayError:

from absolutepay import AbsolutePayError

try:
    ap.invoices.list()
except AbsolutePayError as e:
    print(e.status, e.code, e.detail, e.request_id)
    if e.is_rate_limited:  # 429 — back off and retry
        ...
    if e.is_auth:          # 401/403 — bad creds, missing scope, or bad signature
        ...

Webhooks

Verify the signature and parse the event in one call. Pass the raw request body (bytes or str), the request headers, and your app's callback secret (whsec_…):

from absolutepay import construct_event, WebhookSignatureError

# e.g. in a Flask handler
raw = request.get_data()  # RAW bytes — do not re-serialize
try:
    event = construct_event(raw, dict(request.headers), os.environ["ABSOLUTEPAY_WEBHOOK_SECRET"])
except WebhookSignatureError:
    return "", 400

if event["type"] == "payment.succeeded":
    fulfill(event["data"])
return "", 200

The freshness (replay) window defaults to 5 minutes; pass tolerance_ms=0 to disable it.

Security

• Server-side only. The API key + signing secret authenticate as your workspace — never ship them to a browser or mobile app.
• Requests are sent over HTTPS only (except localhost for local development).
• The Idempotency-Key header (on payouts) is intentionally not part of the signed canonical string.
