A taste of the API

Three lines to a payment. Three more to an IBAN.

POST /v1/payments — accept a card

curl

curl https://api.averrapay.com/v1/payments \
  -u "sk_live_:" \
  -d amount=9900 \
  -d currency="EUR" \
  -d source="tok_..." \
  -d capture=true

POST /v1/iban — issue a virtual IBAN

node

const iban = await averra.iban.create({
  type:     "virtual",
  currency: "EUR",
  owner:    {
    legal_name: "Acme Ltd",
    kyc_id:     "kyc_..."
  }
});

POST /v1/payouts — pay anywhere

python

averra.payouts.create(
    amount=250000,
    currency="USD",
    destination={
        "type":    "bank_account",
        "country": "US",
        "account": "123456789",
        "routing": "021000021"
    },
    rail="ach_same_day"
)

Built the way engineers expect

No surprises. No hidden state.

Auth

Secret keys + restricted keys. Optional mTLS for server-to-server. OAuth 2.0 for delegated access.

Idempotency

Every mutating endpoint accepts Idempotency-Key. Replays return the original result.

Webhooks

Signed with HMAC. Exponential retries up to 72 hours. Per-endpoint event subscription.

Errors

Structured codes, human messages, machine-readable categories. 4xx = you, 5xx = us.

Pagination & filtering

Cursor pagination. Field selection. Predictable list endpoints, predictable response shape.

SDKs

Node, Python, Go, Ruby, PHP, .NET — fully typed where the language allows.
