API documentation

VersionFixer exposes authenticated REST endpoints for account jobs, conversion requests, worker status, and API key rotation.

The API is built for agencies, print shops and partner tools that need automated compatibility jobs.

Authentication

Use a VersionFixer API key in the Authorization: Bearer header or X-VersionFixer-Key header.

Create job

POST /wp-json/versionfixer/v1/jobs with multipart form fields: file, target, options, and optional service.

List jobs

GET /wp-json/versionfixer/v1/jobs returns recent jobs for the authenticated account.

Formats

GET /wp-json/versionfixer/v1/formats returns supported formats, versions, operations, and service targets.

Engines

GET /wp-json/versionfixer/v1/engines returns available conversion engines and worker readiness.

API keys

POST /wp-json/versionfixer/v1/api-key rotates the current account API key.

Authentication

Use Authorization: Bearer vf_live_xxx or X-VersionFixer-Key. API keys are hashed in user meta and can be rotated from the account/API endpoint.

Job creation

POST multipart/form-data to /wp-json/versionfixer/v1/jobs with file, format, target, options and optional service.

Job history

GET /wp-json/versionfixer/v1/jobs returns recent authenticated account jobs with status, credits, worker note and download URL when ready.

Operational model

Workers can be separated by format family so Adobe, CAD, 3D and PDF queues do not block each other.
