Professional WhatsApp PDF conversion with rest api for automated whatsapp pdf conversion & workflow integration included in all tiers
What Is API Integration for Automated Processing?
Professional tier includes REST API access allowing programmatic upload, processing, and download of WhatsApp PDFs. Integrate our conversion service directly into your case management software, customer service platforms, or compliance systems. API handles authentication, file upload, processing job management, status monitoring, webhook notifications, and secure download. Documentation includes SDKs for Python, JavaScript/Node.js, and PHP plus OpenAPI specification.
Why It Matters
Law firms processing dozens of cases monthly need automation - manual uploads are inefficient.
Customer service departments archiving support conversations need systematic workflows.
Compliance teams require scheduled automated archiving.
API integration eliminates manual steps, enables systematic processing at scale, integrates with existing business systems, and allows building custom workflows.
Transform a manual service into automated infrastructure supporting your business processes.

Frequently Asked Questions
What programming languages are supported for the API?
The API is RESTful HTTP/JSON, so any language with HTTP capabilities can use it. We provide official SDKs for Python, JavaScript/Node.js, and PHP with complete examples. The OpenAPI 3.0 specification allows generating clients for other languages (Ruby, Java, C#, Go, etc.) using OpenAPI generators. All API documentation includes curl examples that work from any command line.
How quickly are API processing jobs completed?
API processing uses the same queue as web uploads - typically 1-4 hours depending on queue depth and file size. API jobs don't have priority over web jobs. For guaranteed faster processing, Enterprise tier offers priority queue with 15-minute to 2-hour processing times. Use webhooks to be notified immediately when jobs complete rather than polling.
Can I white-label the PDF output via API?
Yes, Professional tier API includes branding customization parameters: specify logo URL, header/footer text, color schemes, and watermarks in the job creation request. Each API call can have different branding. Enterprise tier adds complete white-labeling with removal of all ChatToPDF branding and custom domain for download links.
What happens if my API webhook endpoint is down?
Webhook failures trigger automatic retries: immediate retry, retry after 1 hour, final retry after 24 hours. If all retries fail, webhook marked as failed but your PDF remains available. Check job status via GET /api/jobs/{id} endpoint anytime - job status persists for 30 days. Consider implementing webhook signature verification to ensure webhooks are authentic (instructions in API documentation).
