Setting up forms can be pain. But JAMStack makes it easier using contact form API. In this article, let's dive in to jamstack contact forms and learn how to integrate it easily into your projects.

## Setting up the contact form

First, you need to setup the contact form. In this example, I'm going to use plain HTML, but in reality, you will be writing for your framework. It could be React, Vue etc. Also check out some [Form Templates](https://web3forms.com/templates)

```html
<form action="" method="POST">

    <input type="text" name="name" required>
    <input type="email" name="email" required>
    <input type="number" name="phone" required>
    <textarea name="message" required></textarea>

    <button type="submit">Submit Form</button>

</form>
```

Now we have a basic contact form ready, let's connect this with a contact form API in the next step.

## Contact form API

In this step, we will be connecting the above form with a contact form API service. We will be using Web3Forms as our API service because it's fast and has a generous free plan. Also the setup is quick and painless.

### Create an Access key
First, go to https://web3forms.com and click on the "Create your Access Key" button and enter your email and submit the form. The form will look like this:

![Create Access Key](/img/blog/access-key.png)

Now, you will receive an email with the access key in your inbox. Please check Promotions or Updates tab as well. The email will look like this:

![Email Screenshot](/img/blog/email-screenshot.png)

## Connect contact form with API

Once you received the access key, let's connect that with your form. First, Let's add a form action URL as described in [Web3Forms Documentation](https://docs.web3forms.com/)

```html
<form action="https://api.web3forms.com/submit" method="POST">
```

Now, add the access key inside the form as a `hidden` field. Make sure the input name is `access_key`. This is used by Web3Forms to send email to your address. Here's how it would look like:

```html
<input type="hidden" name="access_key" value="YOUR_ACCESS_KEY_HERE">
```

## Customizing Web3Forms

Now, our basic stuff is ready for submission, let's go further and make some modifications provided by Web3Forms. Each settings can be added as shown below.

**Custom Redirection after form submission**
```html
<input type="hidden" name="redirect" value="https://web3forms.com/success">
```

**Customize Email Subject**

```html
<input type="hidden" name="subject" value="New Submission from Web3Forms">
```

**Add CC Emails (Pro)**

```html

<input type="hidden" name="ccemail" value="partner@example.com">

<input type="hidden" name="ccemail" value="partner@example.com; sales@website.com">
```

**Send form data to Webhook (Pro)**

```html
<input type="hidden" name="webhook" value="https://webhook.site/xxxxx-xxx-xxxxx" />
```

**And more...**

Web3Forms provides more customizations like adding reCaptcha, hCaptcha, File Attachments and more.. Make sure you check out the documentation for more customization options & example code samples.

## Testing our form

Now that our form is ready, let's test it. Here's the full code:

```html
<form action="https://api.web3forms.com/submit" method="POST">

    <input type="hidden" name="access_key" value="YOUR_ACCESS_KEY_HERE">
    <input type="hidden" name="subject" value="New Submission from Web3Forms">
    <input type="hidden" name="redirect" value="https://web3forms.com/success">

    <input type="text" name="name" required>
    <input type="email" name="email" required>
    <input type="number" name="phone" required>
    <textarea name="message" required></textarea>

    <button type="submit">Submit Form</button>

</form>
```

And here's the result styled with Tailwind CSS:

Now, submit this form and you will receive an email like this:

## Done!

Woohoo, we did it. We just made a working contact form using JAMStack & API. Isn't it easy? Thanks to [Web3Forms](https://web3forms.com/) for providing such an incredible service.

React hook form's useWatch is a great way to get the data from the form. But it cannot easily update other form fields based on the watch field. In this article, we will show you how to modify other form fields using React Hook Form's useWatch

## The Problem

Imagine you have a contact form with a name field and a subject field. Now, you want to change the subject based on the user input in the name field. Here is how you can do it with react hook form and watch.

## The Solution

First import `react-hook-form`:
```jsx
import { useForm } from "react-hook-form";
```

Then, create a form with the `useForm` hook and import the `watch` prop & `setValue` prop as well.

```jsx
const { register, handleSubmit, watch, setValue } = useForm();
```

Then we need to watch the name field and update the subject field based on the user input. For that we have to use the `watch` prop and `setValue` prop.

```jsx
// watch "name" field and set default value to "Someone"
const watchName = watch("name", "Someone")

// set value to "subject" based on the watch field
setValue("subject", `${watchName} sent a message from Web3Forms`)
```

Now, create a `<form>` tag and add the `onSubmit` prop.
```jsx
<form onSubmit={handleSubmit(onSubmit)}>
  <input {...register("name")} />
  <input type="hidden" {...register("subject")} />
  <button type="submit">Submit</button>
</form>
```

That's it. Now, the subject field will be updated based on the user input in the name field. You can also use the [React Hook Form](https://react-hook-form.com/) documentation to learn more.

Here's the full code for reference:

```jsx
import { useForm } from "react-hook-form";


function App() {
  const { register, handleSubmit, watch, setValue } = useForm();

  const watchName = watch("name", "Someone")

  setValue("subject", `${watchName} sent a message from Web3Forms`)

  const onSubmit = async (data, e) => {
    console.log(data);
    // use a contact form API to send the data to your server
    // try: web3forms.com
  };

  return (
    <form onSubmit={handleSubmit(onSubmit)}>
      <input {...register("name")} />
      <input type="hidden" {...register("subject")} />
      <button type="submit">Submit</button>
    </form>
  );
}

```

## Wrapping Up

That's it, React hook form is easier to work with. But you can also do more with Web3Forms like sending the form submissions directly to your email. Please create an access key from [Web3Forms](https://web3forms.com/) to get started.

##  Adding Email Contact Forms to Netlify using Web3Forms

Now, lets move to create our app. Its so simple, using Web3Forms, Here, an `index.html` is more than enough!

So, now lets create an `index.html` file and add some contents to it. Here is how a basic `html` file looks like:

```html
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Web3Forms Contact Form</title>
  </head>
  <body>
    
  </body>
</html>
```

Now, Create your form. First, you should create a `<form>` tag with method as `POST` and `action` as `https://api.web3forms.com/`. See the example 👇

```html
<form action="https://api.web3forms.com/submit" method="POST"></form>
```

Inside the `form`, you should create an `input` with type `hidden` for the Access Key. Replace `YOUR_ACCESS_KEY_HERE` with your actual access key received in your email. This is mandatory.

```html
<input type="hidden" name="access_key" value="YOUR_ACCESS_KEY_HERE" />
```

You can also add many other configuration similarly. Please [Visit our Docs](https://docs.web3forms.com/getting-started/customizations) to see more details.

After, configuring, you can add regular form inputs for `email`, `phone`, `message` etc. Here is how the page looks once added basic form elements.

```html
<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Web3Forms Contact Form</title>
</head>

<body>

    <form action="https://api.web3forms.com/submit" method="POST" id="form">
        <input type="hidden" name="access_key" value="YOUR_ACCESS_KEy_HERE" />
        <input type="hidden" name="subject" value="New Submission from Web3Forms" />
        <input type="hidden" name="redirect" value="https://web3forms.com/success" />
        <input type="checkbox" name="botcheck" id="" style="display: none" />
        <div>
            <label for="name">Full Name</label>
            <input type="text" name="name" id="name" placeholder="John Doe" required />
        </div>
        <div>
            <label for="email">Email Address</label>
            <input type="email" name="email" id="email" placeholder="you@company.com" required />
        </div>
        <div>
            <label for="message">Your Message</label>
            <textarea rows="5" name="message" id="message" placeholder="Your Message" required></textarea>
        </div>
        <button type="submit">
            Send Message
        </button>
    </form>

</body>

</html>
```

## Deploying to Netlify

Now, here come the final step. Deploying our app to netlify, it is super easy, Connect your project using git or upload the files directly using [Netlify Drop](https://app.netlify.com/drop). For this example, we will be using Drop, but we recommend to use `git` deployments.

Once you added the project, it will be available on your dashboard along with a link to preview.
