Get started

Step 1: Identify the Desired Service

Start by determining which service you want to respond to. A list of available services can be found in the relevant sections of the documentation.

Step 2: Establish a Service Endpoint

Create a publicly accessible HTTP endpoint to receive incoming requests using the POST method. This endpoint should be able to return specific payloads based on the requested service.

./pages/api/SERVICE_TYPE.ts

import { NextApiRequest, NextApiResponse } from 'next'
 
export default async function service(
  req: NextApiRequest,
  res: NextApiResponse,
): Promise<void> {
  // ... get the arguments and send the result
  const result = null
  res.json(result).end()
}

Step 3: Implement Request Handling

To process requests from Liteflow, install the @nft/service library by running the following command:


npm i @nft/service

The library will parse and verify incoming requests to ensure they are from the Liteflow infrastructure. To secure communication between your app and Liteflow, you will need to provide your Liteflow secret.

./pages/api/SERVICE_TYPE.ts

import { parseAndVerifyRequest } from '@nft/service'
import { NextApiRequest, NextApiResponse } from 'next'
 
export default async function service(
  req: NextApiRequest,
  res: NextApiResponse,
): Promise<void> {
  const args = await parseAndVerifyRequest<SELECTED_SERVICE>(
    req,
    process.env.LITEFLOW_SERVICE_SECRET,
  )
  console.log(args)
  // TODO: fill the result with the right value based on \`args\`
  const result = null
  res.json(result).end()
}
export const config = {
  api: {
    bodyParser: false,
  },
}

Step 4: Register the Service URL

To integrate your service with your Liteflow account, navigate to the admin panel and add the newly created endpoint in the service section.

Note for Local Development

Please keep in mind that services must be publicly accessible and cannot be hosted on localhost. To test services during local development, you can use tools such as ngrok (opens in a new tab) or localtunnel (opens in a new tab) to expose a local endpoint as a public URL.
