getXmtpFrameMessage
Frames can receive interactions from apps outside of Farcaster, such as from XMTP conversations.
When receiving these interactions you can expect a slightly different response format,
since fields like fid or castId are not available.
You can also use getXmtpFrameMessage to access useful information such as:
- buttonIndex: number
- verifiedWalletAddress: string
- opaqueConversationIdentifier: string
Note that if the message is not valid, it will be undefined.
import { isXmtpFrameRequest, getXmtpFrameMessage } from '@coinbase/onchainkit/xmtp';
import { NextResponse } from 'next/server';
import type { FrameRequest } from '@coinbase/onchainkit';
async function getResponse(req: any): Promise<NextResponse> {
const body: FrameRequest = await req.json();
if (isXmtpFrameRequest(body)) {
const { isValid, message } = await getXmtpFrameMessage(body);
// ... do something with the message if isValid is true
if (isValid) {
const { verifiedWalletAddress } = message;
// ... do something with the verifiedWalletAddress
}
} else {
// ...
}
}Returns
Promise<XmtpFrameValidationResponse>
