Usage Examples

Basic Implementation

import {ElectronicSignature} from "@autohost/web-sdk";

// Simple document signing
const MySigningComponent = () => {
    const handleSignatureComplete = (data) => {
        console.log("Document signed:", data);
        // Process the signed document
        advanceToNextStep();
    };

    return (
        <ElectronicSignature
            reservationId="your-reservation-id"
            document="<h1>Rental Agreement</h1><p>Terms and conditions...</p>"
            callbacks={{
                onSubmit: handleSignatureComplete,
                onError: (error) => console.error("Signature error:", error),
            }}
        />
    );
};

Advanced Configuration

import {ElectronicSignature} from "@autohost/web-sdk";

const AdvancedSigningComponent = () => {
    const [documentReady, setDocumentReady] = useState(false);

    const signatureCallbacks = {
        onScrollToBottom: () => {
            // User has reached the signature area
            console.log("User ready to sign");
            setDocumentReady(true);
        },
        onSubmit: (signatureData) => {
            // Complete signature data with audit trail
            console.log("Signature completed:", {
                timestamp: signatureData.signedDate,
                userLocation: signatureData.geoip,
                ipAddress: signatureData.userIP,
            });

            // Submit to your backend
            submitSignedDocument(signatureData);
        },
        onError: (error) => {
            // Handle signature errors
            showErrorMessage(`Signature failed: ${error}`);
        },
    };

    return (
        <div className="signature-container">
            <ElectronicSignature
                reservationId="res-123456"
                document={yourHtmlDocument}
                title="Property Rental Agreement"
                signatureModes={["draw", "type"]}
                sandbox={true}
                primaryColor="#007bff"
                locale="en"
                callbacks={signatureCallbacks}
            />

            {documentReady && (
                <div className="signature-ready-indicator">Ready to sign ✓</div>
            )}
        </div>
    );
};
