iReceipt PRO blog https://ireceipt.pro/blog Guides and articles on generating PDF and image documents from templates: getting started with the iReceipt PRO API, and longer pieces on HTML-to-PDF rendering. en-us Sun, 08 Nov 2026 12:00:00 +0000 Generate documents with Claude: MCP and Claude Code https://ireceipt.pro/blog/documents-from-claude https://ireceipt.pro/blog/documents-from-claude Sun, 08 Nov 2026 12:00:00 +0000 Generate PDFs from your templates in Claude: an MCP connector you approve once, or a network secret so Claude Code in the cloud calls the API without your key. MCP Claude Claude Code API Sylius invoices still render through wkhtmltopdf. Here is the seam to replace https://ireceipt.pro/sylius-invoice-pdf https://ireceipt.pro/sylius-invoice-pdf Thu, 05 Nov 2026 12:00:00 +0000 sylius/invoicing-plugin v2.3.0 still reaches a wkhtmltopdf binary through knp-snappy-bundle. The plugin has exactly one clean seam, InvoicePdfFileGeneratorInterface, and it is handed the invoice entity rather than HTML. What you replace it with depends on whether you want to keep your Twig template. DocRaptor or iReceipt PRO: one converts documents, the other fills templates https://ireceipt.pro/docraptor-vs-ireceipt-pro https://ireceipt.pro/docraptor-vs-ireceipt-pro Wed, 04 Nov 2026 12:00:00 +0000 DocRaptor takes HTML at request time and renders it with Prince. iReceipt PRO takes a template id and JSON. The choice is decided by where your layout has to live, not by a feature table — and this page says plainly where DocRaptor wins. Running Puppeteer yourself, or calling an API: the honest build-vs-buy https://ireceipt.pro/puppeteer-vs-rendering-api https://ireceipt.pro/puppeteer-vs-rendering-api Tue, 03 Nov 2026 12:00:00 +0000 The twelve lines are the cheap part. An inventory of what owning a renderer actually costs - binary, container, concurrency, version treadmill - and the one question that decides it. Migrating off wkhtmltopdf: what actually breaks, and what to move to https://ireceipt.pro/wkhtmltopdf-migration https://ireceipt.pro/wkhtmltopdf-migration Sun, 01 Nov 2026 12:00:00 +0000 Your template survives, because QtWebKit never let it get clever. The four behaviours that do not carry across, and how to pick a destination. Authentication: one header, and four things that look like a bad key https://ireceipt.pro/authentication https://ireceipt.pro/authentication Wed, 28 Oct 2026 12:00:00 +0000 Send the key in the Authorization header or as ?token=. X-Api-Key and ?api_key= are not read. Which check answers first, what 401, 403, 400 and 404 mean, and what CORS and allowed domains do and do not protect. When somebody else picks the format: one template per jurisdiction, not per customer https://ireceipt.pro/one-template-per-jurisdiction https://ireceipt.pro/one-template-per-jurisdiction Tue, 27 Oct 2026 12:00:00 +0000 When the recipient sets the document format, the layout count is a rate rather than a number and presentation becomes correctness. Four ways to build it, and the one most products ship first. Errors and retries: what the API sends back when it isn't sending a file https://ireceipt.pro/errors-and-retries https://ireceipt.pro/errors-and-retries Mon, 26 Oct 2026 12:00:00 +0000 Success is 201 with file bytes. Every failure is a small JSON object except one, which is HTML - and the SDK retries only the failures a retry could fix. What a Shopware document renderer is actually handed https://ireceipt.pro/shopware-document-renderer https://ireceipt.pro/shopware-document-renderer Sun, 25 Oct 2026 12:00:00 +0000 Every published example of a Shopware format renderer declares a dependency on html, so everyone assumes the slot takes HTML. The abstract class defaults to no dependency and RenderInput carries the order. That changes what you can build in it. Quickstart: your first PDF in five minutes https://ireceipt.pro/quickstart https://ireceipt.pro/quickstart Sun, 11 Oct 2026 12:00:00 +0000 Install the SDK, call one method with a template ID and a JSON object, and write the PDF to disk. A working file before you build any integration code.
