Postman

Generate your first image with the official Postman collection.

Open in Postman

The collection includes examples for HTML/CSS images, website screenshots, and PDFs, plus a parameter reference for image and template requests. You can browse the collection documentation before forking it.

1. Open the collection and fork it into your own Postman workspace.
2. Create an environment with api_id and api_key from your HCTI dashboard. Keep credential values private, and select that environment before sending requests.
3. Open Use cases → Getting started with a simple request. Change the url field under Body → form-data to the webpage you want to capture, or use the supplied example.
4. Click Send. The API returns JSON containing the generated image’s url and id.
5. Open View or download the latest image and click Send to retrieve the file. Successful creation requests save image_url automatically for this step.

Image creation requires the images:create permission and uses your account’s image credits. The collection uses HTTP Basic authentication: api_id is the username and api_key is the password. See API keys and authentication for details.

• Use cases includes HTML to image, full-page and mobile screenshots, cookie-banner blocking, element cropping, and PDF generation.
• Full API reference lists the supported parameters for the included image and template operations. Open Body → form-data, check optional rows to include them, and edit their values. Each parameter has a description and documentation link. Unchecked rows are omitted; example values are suggestions, not API defaults.

To render a template, set template_id to a template in your account and match template_values to its variables. You can also run Create a template first, which saves the new template ID. Template creation requires templates:create_update.

Run the examples individually. Saved response examples are illustrative and contain placeholder image IDs; send a request with your credentials to generate your own image URL.

You can also create a POST request to https://hcti.io/v1/image. Select Basic Auth in the Authorization tab and enter your API ID and API key. Under Body → form-data, add html and optional css, or add url to capture a webpage. Postman sets the form’s Content-Type header automatically.
