Stripe

github.com/KARTIKrocks/gopay/stripe is the most complete provider — it implements every optional interface gopay defines.

import (
    payment "github.com/KARTIKrocks/gopay"
    "github.com/KARTIKrocks/gopay/stripe"
)

config := stripe.DefaultConfig().
    WithSecretKey("sk_test_...")

provider, err := stripe.NewProvider(config)
if err != nil {
    log.Fatal(err)
}

client, err := payment.NewClient(provider)

NewProvider returns payment.ErrInvalidConfig if SecretKey is empty.

Config

Field	Set via	Notes
SecretKey	WithSecretKey	Required
WebhookSecret	WithWebhookSecret	Required to call VerifyWebhook
HTTPClient	WithHTTPClient	Optional, for custom timeouts/transport

Support matrix

Capability	Supported
Payments, Refunds	✓
Customers	✓
Payment Methods	✓
Setup Intents	✓ — the only provider that does
Subscriptions	✓ (open-ended — TotalCount is ignored)
Invoices	✓
Webhooks	✓ (Stripe-Signature header)
Listing	✓ (cursor = object ID, starting_after)

Notes

• CaptureMethod maps directly onto Stripe's own manual/automatic capture on a PaymentIntent.
• Subscriptions are open-ended by default — Stripe ignores SubscriptionRequest.TotalCount (see Subscriptions for how this differs from Razorpay).
• Payment.Raw, Refund.Raw, etc. carry the full Stripe API response as map[string]any for anything not surfaced on the normalized struct.
