API Reference

Everything you need to send a drawing and receive a PDF on your webhook.

Authentication

Every request needs your API key as a bearer token in the Authorization header. Find and rotate your key from the dashboard.

Authorization: Bearer sk_live_xxxxxxxxxxxxxxxx

Convert a file

POST /v1/convert

One endpoint handles every tool. Pass a strategy to tell us which operation to run. The request returns immediately with a job id. The finished file is delivered separately to your webhook, not in this response.

Request: multipart/form-data

file	binary, required	The document to process. Repeat this field for strategies that accept multiple files, e.g. `merge_pdf`.
strategy	string, required	Which operation to run. See Strategies below.
webhook_url	string, optional	Overrides your account's default webhook URL for this request only.

curl

curl -X POST https://api.anyconvert.app/v1/convert \

  -F "file=@site-plan.dwg" \
  -F "strategy=dwg_to_pdf" \

  "strategy": "dwg_to_pdf",
  "status": "processing"
}

Strategies

Every tool runs through the same /v1/convert endpoint; this value just tells us which one.

dwg_to_pdf	DWG to PDF	From $0.90 / doc
pdf_to_word	PDF to Word	From $0.27 / doc
merge_pdf	Merge PDF	From $0.18 / doc
jpg_to_pdf	JPG to PDF	From $0.14 / doc
sign_pdf	Sign PDF	From $0.32 / doc
edit_pdf	Edit PDF	From $0.27 / doc
compress_pdf	Compress PDF	From $0.14 / doc

Webhook delivery

When conversion finishes, we POST the result to your webhook_url (or your account default, set in the dashboard).

POST https://yourapp.com/webhooks/pdf
X-Signature: sha256=8b1a99...

{
  "job_id": "job_8f3a2c19",
  "status": "completed",
  "file_url": "https://files.anyconvert.app/job_8f3a2c19.pdf"
}

On failure, status is "failed" and an error field explains why. The file_url field is omitted.

Verifying the signature

The X-Signature header is an HMAC-SHA256 of the raw request body, signed with your API secret. Check it before trusting a payload. Respond 200 quickly, and do any slow work after acknowledging receipt.

Retry policy: 3 attempts with exponential backoff over 24 hours.

402	No credits remaining on your account

500	Conversion failed. Retry, or contact support if it persists
