HTML/CSS to Image Screenshot API Tutorial for WordPress Sites in India

Send a secure server-side WordPress request to HTML/CSS to Image, handle the returned image URL, and understand the limits and costs to verify from India.

To create a screenshot from WordPress with HTML/CSS to Image (HCTI), send a server-side POST request to https://hcti.io/v1/image using HTTP Basic authentication: your API ID is the username and your API key is the password. Send either HTML or a public page URL, not both. The example below uses WordPress’s HTTP API, checks failures, and keeps credentials off the browser.

Choose what HCTI should render

HCTI accepts one of two main inputs: HTML your WordPress application creates, or a fully qualified URL for a public webpage. CSS is optional when sending HTML. Do not send both html and url; the URL takes precedence.

  • Use html when your plugin or theme builds the markup and styles to render.
  • Use url when the target is already published and publicly accessible. HCTI does not automate an interactive login flow.

Store the API credentials on the server

Get the API ID and API key from your HCTI account. HCTI advises treating the API key like a password and supports permission-scoped keys. Store credentials in server-side configuration, environment variables, or a suitable secret manager. Do not put the key in browser JavaScript, a public shortcode attribute, or rendered page HTML.

For example, define constants in a protected server configuration rather than a theme template:

define( 'HCTI_API_ID', getenv( 'HCTI_API_ID' ) );
define( 'HCTI_API_KEY', getenv( 'HCTI_API_KEY' ) );

Restrict each key to the permissions the WordPress integration needs. Do not log authorization headers or include credentials in user-visible error messages.

Call the API with WordPress HTTP helpers

WordPress’s wp_remote_post() sends the request from PHP, so the HCTI secret remains on the server. This illustrative example uses a public page URL; change the payload to html if you are rendering markup generated by your application. It is an integration pattern, not a tested plugin. Confirm the current endpoint’s accepted body format and success-response fields against HCTI’s live API documentation.

<?php
function mysite_hcti_screenshot( $public_page_url ) {
    if ( ! defined( 'HCTI_API_ID' ) || ! defined( 'HCTI_API_KEY' ) ) {
        return new WP_Error( 'hcti_credentials_missing', 'Screenshot credentials are not configured.' );
    }

    // In production, constrain this value to URLs your application is allowed to request.
    if ( ! is_string( $public_page_url ) || ! wp_http_validate_url( $public_page_url ) ) {
        return new WP_Error( 'hcti_url_invalid', 'Enter a valid public page URL.' );
    }

    $payload = array( 'url' => $public_page_url );
    $args = array(
        'headers' => array(
            'Authorization' => 'Basic ' . base64_encode( HCTI_API_ID . ':' . HCTI_API_KEY ),
            'Content-Type'  => 'application/json',
        ),
        'body'    => wp_json_encode( $payload ),
        'timeout' => 30,
    );

    $response = wp_remote_post( 'https://hcti.io/v1/image', $args );

    if ( is_wp_error( $response ) ) {
        // Log a sanitized diagnostic if needed; do not expose credentials to visitors.
        return new WP_Error( 'hcti_transport_error', 'The screenshot request could not reach the service.' );
    }

    $status = wp_remote_retrieve_response_code( $response );
    $body   = wp_remote_retrieve_body( $response );

    if ( $status < 200 || $status >= 300 ) {
        return new WP_Error( 'hcti_http_error', 'The screenshot service returned an unsuccessful HTTP status.', array( 'status' => $status ) );
    }

    $data = json_decode( $body, true );
    if ( ! is_array( $data ) ) {
        return new WP_Error( 'hcti_response_invalid', 'The screenshot service returned an unreadable response.' );
    }

    // Check the current HCTI response schema and validate its image URL field here.
    return $data;
}

The API uses HTTP Basic authentication, with the API ID as the username and API key as the password. The example encodes those two values in the Authorization header. The endpoint, accepted content type, and returned JSON field names can change, so verify them against the current API reference before deploying. WordPress’s HTTP API provides response-code and body helpers for handling the result.

Render HTML instead of a URL

When the page content is generated inside WordPress, send an HTML payload, optionally with CSS, in place of the URL payload. Keep the request to one input type; do not include both fields. HTML supplied by users should be constrained and sanitized according to the purpose of your feature.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Do not trigger a render on every page view by default

Choose when a screenshot should be created: for example, an explicit admin action, a content update, or a scheduled job. Generating on every visitor request can add latency and create repeated API work. Cache or reuse results where the same content does not need a fresh image; check the current HCTI API reference for caching and deduplication behavior relevant to your request.

Show the returned image or import it into WordPress

HCTI returns an image URL that can be used directly in your site. After checking the response schema and validating that the returned value is a URL from the expected service, render it as an image, escaping the attribute:

HCTI documents PNG, JPG, WebP, and PDF output. Its documentation says generated URLs remain available while the account is active and are cached and optimized through Cloudflare; availability is therefore subject to account status and service terms, not an unconditional permanence guarantee.

Displaying the remote URL and creating a local WordPress Media Library attachment are different workflows. A local attachment requires downloading the generated file and creating a WordPress media item; the available WordPress media reference describes the endpoint but does not establish a complete upload recipe here. Do not treat simply storing the remote URL as a Media Library import.

Protect URL-based requests and handle private pages carefully

If a URL comes from a visitor or another untrusted input, validate and constrain it before your server makes a request. An unrestricted server-side URL fetch can be abused to target destinations the site should not access. Limit allowed hosts or accept only URLs tied to content managed by your application, and check WordPress’s current guidance for user-controlled request destinations before production use.

HCTI expects a public webpage for URL screenshots and does not perform an interactive sign-in. For a page you are authorized to access, its documentation describes sending short-lived session cookies or authorization tokens in allowed headers. Do not use this as a way to capture pages without permission, and avoid storing long-lived user credentials in the integration.

Troubleshoot common integration failures

Symptom Likely cause What to check
WordPress returns a transport error The host could not complete the outbound request, or the request timed out. Check server outbound HTTPS connectivity, DNS/TLS configuration, and timeout policy. Log a sanitized error rather than the authorization header.
HCTI returns an unsuccessful HTTP status Credentials, permissions, request fields, or payload format may be wrong. Confirm API ID and key, key permissions, endpoint, and current request schema. Do not expose an unreviewed vendor error body to site visitors.
Response cannot be decoded as JSON The service may have returned an unexpected body, or the request failed in a way not handled by the assumed schema. Inspect the HTTP status and a safely redacted diagnostic, then compare the response with the current API documentation.
The returned image does not render The image URL may be missing, malformed, expired under account/service terms, or incorrectly escaped. Validate the response field and URL, use esc_url() in HTML output, and check whether the HCTI account remains active.
A URL screenshot shows an access-denied or login page The destination is not public or depends on an interactive login. Use a public page, or only for a page you are authorized to capture, investigate HCTI’s documented short-lived cookie or authorization-header options.
