For product teams, developers and service providers.

The Fixer engine
Build your service. Leave the PDF corrections to us.
Connect the remediation capabilities you can already try in Porter Fixer to the way your team works.
More than a compliance check
Fixer can add missing alternative text and bookmarks automatically, alongside its accessibility corrections.
Results you can inspect
Compare validation before and after processing. Use remaining errors and warnings to decide what needs a closer look.
Private by default
Our team does not inspect file contents unless you explicitly share the PDF with Porter for investigation and improvement.
Automated remediation cannot resolve every issue. Some documents need changes to their source, design or content; validation helps identify the remaining work.
Built for integration
Choose how to process each PDF, connect the results to your application and keep improving retained files.
Validate, fix, or both
Choose validation-only, repair-only, or repair with before-and-after validation. Validation-only uses no page credits, including when your balance is zero. An API-enabled plan is required.
Explore processing modesNotifications that fit your workflow
Receive signed webhooks when a job completes, fails, or a new output is published. Test your endpoint and inspect or resend deliveries in API setup.
See how webhooks workAutomatic reruns
Available on every plan that includes API access. Opt in when you fix and validate a PDF, and retained files can benefit as new corrections become available. Receive a webhook when an improved output is published.

Organisation owners and administrators can create and revoke API keys, configure webhooks and inspect jobs. Follow a working example to run your first validation.
Set up your API connectionFor your technical team
Start with the API documentation.
Start with working Python, JavaScript and shell examples, a downloadable OpenAPI schema and a complete endpoint reference. Contact us about reseller integrations or custom requirements.
Read the API referenceDownload the OpenAPI schema- Team or reseller access
- Higher-tier Fixer plans can provide API access for your own team, without resale rights. Reseller integrations require a separate API agreement.
- Processing & results
- Submit PDFs, follow job status, retrieve structured validation reports and download repaired files. Use your own document reference to connect each job to your application.
- Volume & pricing
- Reseller API pricing offers better rates at high volumes. White labelling is available at an additional cost, so you can offer the service under your own brand. Contact us for a quote based on your expected usage.
- File lifecycle & privacy
- Choose 14-day, 90-day or continued retention and delete files through the API. API uploads are not shared with Porter staff by default. You control whether to enable automatic reruns.
Good questions
Before you connect.
Can we test the results before integrating?
Yes. Try your PDFs in the browser, or use the quickstart to validate a PDF directly through the API. Validation-only uses no page credits, but requires a plan with API access. Organisation owners and administrators can create a key in API setup. Contact us about reseller access.
Is this for existing PDFs or generating new ones?
Fixer remediates existing PDF files. It fits workflows where a PDF has already been uploaded, exported or generated. Porter Original is our separate service for producing accessible documents.
Can we offer remediation to our customers?
Yes, with a separate reseller API agreement. Browser subscriptions do not include resale rights. Resellers benefit from better rates at high volumes, and white labelling under your own brand is available at an additional cost.
Does a monthly Fixer plan include API access?
On higher tiers, you can get an API connection for use by your own team. This does not allow you to resell the service. API access for resellers requires a separate agreement and is not included in browser subscriptions.
