Request Example

gRPC

Access the example here

// sendTransactions is an example function for sending a transaction.
// It's designed to reuse an existing gRPC client connection to avoid connection latency.
func sendTransactions(client basepb.BaseApiClient, authToken string, rawTxString string) {
	log.Println("[SendTx] Sending transaction...")
	ctx, cancel := context.WithTimeout(context.Background(), 3*time.Second)
	defer cancel()

	// Add the authentication token to the outgoing request's metadata.
	md := metadata.Pairs("authorization", authToken)
	ctx = metadata.NewOutgoingContext(ctx, md)

	req := &basepb.SendTransactionRequest{
		RawTransaction: rawTxString,
	}

	res, err := client.SendTransaction(ctx, req)
	if err != nil {
		log.Printf("[SendTx] Failed to send transaction: %v", err)
	} else {
		log.Printf("[SendTx] Transaction sent successfully. Hash: %s", res.GetTxHash())
	}
