Step by Step Guide to Building a Typeform API Integration in JS

Introduction

Hey there, fellow developer! Ready to supercharge your forms with the Typeform API? Let's dive into building a slick integration using the @typeform/api-client package. This powerhouse lets you fetch form data, handle responses, and even create forms on the fly. Buckle up!

Prerequisites

Before we jump in, make sure you've got:

• Node.js and npm installed (you're a pro, so I'm sure you do)
• A Typeform account and API key (grab one from your account settings if you haven't already)

Setting up the project

Let's get this show on the road:

mkdir typeform-integration && cd typeform-integration
npm init -y
npm install @typeform/api-client

Authenticating with the Typeform API

Time to make friends with the API:

const { createClient } = require('@typeform/api-client')

const typeformAPI = createClient({ token: 'YOUR_API_KEY_HERE' })

Fetching form data

Let's grab some forms:

async function getForms() {
  try {
    const forms = await typeformAPI.forms.list()
    console.log(forms)
  } catch (error) {
    console.error('Oops!', error)
  }
}

getForms()

Want details on a specific form? No sweat:

async function getFormDetails(formId) {
  try {
    const form = await typeformAPI.forms.get({ uid: formId })
    console.log(form)
  } catch (error) {
    console.error('Uh-oh!', error)
  }
}

getFormDetails('YOUR_FORM_ID')

Working with responses

Let's fetch those valuable responses:

async function getResponses(formId) {
  try {
    const responses = await typeformAPI.responses.list({ uid: formId })
    console.log(responses)
  } catch (error) {
    console.error('Yikes!', error)
  }
}

getResponses('YOUR_FORM_ID')

Got a ton of responses? Pagination's got your back:

async function getAllResponses(formId) {
  let allResponses = []
  let pageToken = null

  do {
    const { items, page_count } = await typeformAPI.responses.list({
      uid: formId,
      page_size: 1000,
      after: pageToken
    })
    allResponses = allResponses.concat(items)
    pageToken = page_count > 0 ? items[items.length - 1].token : null
  } while (pageToken)

  console.log(allResponses)
}

getAllResponses('YOUR_FORM_ID')

Webhooks integration

Real-time data? You got it. Set up a webhook:

async function createWebhook(formId, url) {
  try {
    const webhook = await typeformAPI.webhooks.create({
      uid: formId,
      tag: 'my-cool-webhook',
      url: url,
      enabled: true
    })
    console.log('Webhook created:', webhook)
  } catch (error) {
    console.error('Webhook creation failed:', error)
  }
}

createWebhook('YOUR_FORM_ID', 'https://your-server.com/webhook')

Now, handle that incoming data like a boss:

const express = require('express')
const app = express()

app.use(express.json())

app.post('/webhook', (req, res) => {
  const formResponse = req.body
  console.log('New response:', formResponse)
  res.sendStatus(200)
})

app.listen(3000, () => console.log('Webhook server running on port 3000'))

Error handling and best practices

Always wrap your API calls in try-catch blocks (like we've been doing). And hey, respect those rate limits – Typeform's got 'em for a reason!

Advanced usage

Feeling adventurous? Let's update a form field:

async function updateFormField(formId, fieldId, newTitle) {
  try {
    await typeformAPI.forms.update({
      uid: formId,
      data: {
        fields: [{ id: fieldId, title: newTitle }]
      }
    })
    console.log('Field updated successfully!')
  } catch (error) {
    console.error('Update failed:', error)
  }
}

updateFormField('YOUR_FORM_ID', 'FIELD_ID', 'New awesome question')

Conclusion

And there you have it! You're now armed and dangerous with Typeform API integration skills. Remember, this is just scratching the surface – there's a whole world of form-building possibilities out there. Check out the Typeform API docs for more cool tricks.

Now go forth and create some killer forms! 🚀
