Go SDK

Terminal window
go get github.com/gryphem-pay/gryphem-pay-go
client, err := gryphempay.New(os.Getenv("GRYPHEM_API_KEY"),
  gryphempay.WithBaseURL("https://api.feitpay.com"),
  gryphempay.WithMaxRetries(2),
)


intent, err := client.PaymentIntents.Create(ctx, &gryphempay.PaymentIntentCreateParams{
  StoreID: "store_YOUR_STORE_ID", Amount: "59.90", Currency: "EUR", IdempotencyKey: "order-123",
})


for pi, err := range client.PaymentIntents.All(ctx, &gryphempay.PaymentIntentListParams{
  Status: []gryphempay.PaymentStatus{gryphempay.StatusConfirmed},
}) {
  if err != nil {
    return err
  }
  fmt.Println(pi.ID, pi.Fulfillable)
}

Errors are *gryphempay.Error with Type, Code, Param, Status, RequestID and RetryAfter; use gryphempay.ErrorType(err) for quick checks. The client is safe for concurrent use; reuse one instance.

Services: PaymentIntents (Create, Get, List, All, Cancel, Resolve, Timeline), CheckoutSessions, WebhookEndpoints (Create, List, RotateSecret, SendTest), WebhookDeliveries (Get, Retry) and Platform (Capabilities). For other endpoints, see the API reference.

Webhooks

Section titled “Webhooks”
event, err := webhook.Verify(body, r.Header.Get(webhook.SignatureHeader), []string{secret, previousSecret}, nil)
if err != nil {
  http.Error(w, string(webhook.ReasonOf(err)), http.StatusBadRequest)
  return
}
data, _ := event.PaymentData()

webhook.Options{Tolerance: …, Now: …} customises tolerance and time for tests; webhook.GenerateTestHeader creates valid headers.
