Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsTo generate a screenshot from a WordPress site with HTML/CSS to Image (HCTI), send a server-side POST request to https://hcti.io/v1/image using WordPress’s HTTP API. Authenticate with your HCTI API ID and API key via HTTP Basic authentication, then send either HTML or a public page URL. Keep the API key on the server, check the response before displaying its image URL, and avoid generating a new image on every page view unless your workflow requires it.
Choose HTML or a public URL
HCTI accepts one of two rendering inputs: HTML that your WordPress application supplies, or a fully qualified URL for a public webpage. CSS can be included with HTML when you need to control the rendered appearance. Do not send both inputs in one request: the URL takes precedence over HTML.
- Use HTML when WordPress generates the markup and you want to render that content directly.
- Use a URL when the page is already publicly reachable and you want HCTI to capture that page.
HCTI documents PNG, JPG, WebP, and PDF output formats. Check the current API reference for the request parameters and response schema relevant to the format you need: HCTI API documentation.
Keep the HCTI credentials on the server
Get the API ID and API key from your HCTI account. HCTI uses the ID as the HTTP Basic username and the key as the password. Its documentation advises treating the API key like a password and keeping it in a server environment or secret manager; HCTI also supports permission-scoped keys. Use the narrowest permissions suitable for the integration.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
- Store credentials in server-side configuration, environment variables, or a suitable secret store.
- Do not put the API key in browser JavaScript, a shortcode attribute, a public theme file, or rendered page HTML.
- Do not log the Authorization header or expose raw vendor errors to visitors.
For a simple WordPress deployment, define the credentials in server-side configuration and read them in PHP. Avoid committing real credentials to a public code repository.
Call HCTI from WordPress PHP
Use WordPress’s wp_remote_post() helper so the authenticated request runs on the server. The example below demonstrates a URL capture. It is an illustrative integration, not a tested plugin; confirm the current endpoint’s accepted body format and JSON response fields against HCTI’s live documentation before deploying it.

WordPress’s HTTP API provides wp_remote_post() for the request and helpers such as wp_remote_retrieve_response_code() and wp_remote_retrieve_body() to inspect the result. See the WordPress HTTP API guide and function reference.
If you generate HTML rather than capture a URL, construct the request body with an html field and, where needed, a CSS field, instead of the url field. The endpoint accepts one rendering input, so do not include both.

Display the returned image or import it into WordPress
HCTI returns a URL for the generated image. Once the response schema is verified and the URL has been validated, you can use it as the src of an image in a WordPress template or block. HCTI says the URL remains available while the account is active and is cached and optimized through Cloudflare; treat that availability as subject to account activity and the service’s terms.
Displaying the remote image and creating a local Media Library attachment are different workflows. A Media Library import requires downloading the image and creating an attachment in WordPress; it is not accomplished merely by printing HCTI’s URL. WordPress’s media REST resource is documented at the Media endpoint reference, but the reviewed material does not establish a complete upload recipe.

Control when screenshots are generated
Choose the trigger that matches the job. A one-time administrator action, an on-demand feature, and a scheduled batch have different costs and failure patterns. Avoid calling HCTI on every ordinary page view if the screenshot can be reused.
- Cache or deduplicate repeated requests for unchanged content where appropriate. HCTI documents caching and request deduplication; verify current parameters and behavior in its API reference.
- Use a bounded timeout and handle transport errors separately from HTTP failures and malformed JSON.
- Limit request frequency for batch or front-end workflows, and decide how the site should behave if the image cannot be generated.
- Validate target URLs before a server-side request. If visitors can influence the destination, restrict accepted hosts and paths to prevent your server from being used to request unintended addresses.
Capture pages that require authorization
HCTI’s URL capture is intended for public webpages and does not automate an interactive login flow. For a page your application is authorized to access, HCTI’s documentation describes using short-lived session cookies or authorization tokens in allowed headers. Do not use this as a way to access pages without permission, and avoid sending long-lived user credentials when a short-lived token will work.

Troubleshoot common failures
| Symptom | Likely cause | What to check |
|---|---|---|
| WordPress returns a transport error | The outbound request could not complete, for example because of a network, DNS, TLS, or timeout issue. | Check server connectivity and the configured timeout. Log a safe diagnostic, without the API key or Authorization header. |
| HCTI responds with an unsuccessful HTTP status | Credentials, request fields, permissions, or another API requirement may be wrong. | Check the API ID/key pair, the endpoint, and the current request documentation. Do not publish an unreviewed raw error body. |
| The JSON cannot be decoded or contains no expected image URL | The response may differ from the assumed schema, or the request may have failed in a way the code did not account for. | Inspect a safely redacted response in an administrator-only context and update the field handling to match HCTI’s current schema. |
| The captured page is blank or incomplete | The target may not be publicly reachable, may depend on interactive authentication, or may not have finished rendering as expected. | Confirm the page is public or use an authorized supported header approach. Review HCTI’s current rendering options for waits or other page-specific needs. |
| The key appears in browser tools or page source | The request was made from frontend code or the secret was embedded in markup. | Move the request to server-side PHP, remove the exposed key, and rotate it in HCTI if it was disclosed. |

Frequently Asked Questions
Can HCTI capture a WordPress page that visitors cannot access?
Not through an automated interactive login flow. Use an authorized, supported short-lived cookie or token approach only when you have permission to access the page.
Does this example save the screenshot in the WordPress Media Library?
No. It handles the returned image URL; importing a file into Media Library is a separate download-and-attachment workflow.
