# Nodes and components
Forms lets you add nodes and components, such as fields, blocks, and widgets for your users to interact with the form. You can then reference the data input, from components, in your forms and flows.
## Form nodes
There are five types of form nodes: Start, Step, Flow, Router and Ending screen. These nodes have a very specific purpose for the structure of the form.
## Step node
Step nodes are the visual representation of the form. They can contain any number of components, such as fields, blocks, and widgets where the user can fill in their data.

To learn more, read [Custom Field Components for Forms](/docs/customize/forms/custom-field-components).
### Blocks components
Blocks are UI components that add functionality to your forms but do not gather user information.
#### Available blocks in Forms
The available blocks are:
A button that lets users continue to the next form node.
* Before continuing, field validation rules are applied and validated on the client-side and server-side. If field validation rules fail, an error message is displayed for the user to verify.
* If the next node is a flow node, a spinner loader is displayed until the flow completes. If the flow fails or returns a custom error message, an error message is displayed.
A button that lets users go to the previous step node.
If a user selects the previous button, field validation rules are re-run again even if no change to input data is done before continuing.
A button that lets users skip the current step and directly jumps to the destination node.
When skipping the current step, we won't validate and neither collect any filled out information of the current step.
A component that lets users re-run a flow to generate and send a new OTP code
if a user selects the resend button, the associated flow will generate and send a new OTP code.
| Settings | Description |

| Text alignment | Select text alignment, left, center, or right |
| Text | Default text displayed when users select the resend button |
| Button text | Button text |
| Waiting text | Text displayed when users have selected the resend button. Replaces `Text` and the `Button text` settings. Use the `“{{remaining_seconds}}”` variable to dynamically display the remaining number of seconds until the send button is enabled again. For example: “Resend in `{{remaining_seconds}}` seconds”. |
| Flow | Flow executed after the user selects the resend button. |
| Max attempts | The maximum number of attempts the user can select the resend button |
| Waiting time | The waiting time between attempts in seconds. |
A rich text block to personalize the step node with additional information.
A line to divide different sections of the step node. It can contain a small text.

A widget that helps protect your website from spam and abuse by verifying that a user is a human and not a bot.
The widget supports:
* Score-based (v3)
* Challenge (v2)
* Invisible reCAPTCHA badge
Differences between `v2` and `v3`:
* `v2` requires user interaction with visible challenges, such as clicking a checkbox or solving puzzles.
* `v3` runs in the background and provides a score based on user behavior, without requiring user interaction. When using this version, make sure to implement additional business logic to handle the score and determine if further action is needed.
##### Google reCAPTCHA widget settings
The Google reCAPTCHA widget settings include:
| Settings | Description |
| ---------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Site key | The public site key used to initialize the reCAPTCHA on your website. You can create it in [Google reCAPTCHA console](https://www.google.com/recaptcha/admin/create) or your Google Cloud Platform project. |
| Secret key | The secret key used to communicate securely with the reCAPTCHA service server-side. You can create it in [Google reCAPTCHA console](https://www.google.com/recaptcha/admin/create) or your Google Cloud Platform project. |
##### Google reCAPTCHA output value

Example of `v2` response:
```json lines theme={null}
{
"recaptcha_widget_id": {

"hostname": "auth.example.com"
}
}
```

{
"recaptcha_widget_id": {
"success": true,
"challenge_ts": "2025-03-26T11:22:18Z",
"hostname": "auth.example.com",
"score": 0.9
}
}
```
A widget that lets a user verify their identity using verifiable credentials stored in their digital wallet.
##### Verifiable Credentials widget settings
The Verifiable Credentials widget settings include:
| Settings | Description |
| -------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| URL | The URL value used to generate the QR code. This value is returned in the `engagement` property of the verification request. |
| Link text | Alternative text that will be displayed for users who cannot scan the QR code and prefer to open the link directly on their device. |
| Size | The size of the QR code. |
| Public token | The access token required to consume the polling endpoint. Please ensure the token is generated with only the `read:verification_request` scope to avoid exposing access to other resources. |
| Verification ID | The verification ID generated when you start the verification request. |
| Maximum waiting time | The maximum amount of time to wait for the verification process to complete. Once the set time is reached, polling will stop and an error will be thrown, regardless of the verification status. |

"presentation": {} // The presentation contains the claims provided by the wallet in response to the presentation definition.
}
}
```
## Router node
Router nodes let you add rules to create conditional logic jumps between nodes.
By default, a router node has a single pass-through rule named **Default Case** that connects to other nodes. You can add additional rules based on a set of conditions that a variable must meet to then connect to other nodes. To learn more, read [Router.](/docs/customize/forms/routers)
## Flow node
Flow nodes let you add and create custom logic and integration flows to your forms. To learn more, read [Flows.](/docs/customize/forms/flows)
## Start node
Start nodes are not visible to the user. It is where you can configure hidden field variables, such as user attributes when [rendering a form with an Action.](/docs/customize/forms/render)
## Ending screen node
Every form has an Ending screen node. By default this node resumes the authentication flow and this is where you can configure an After submission flow.
