Validate, timestamp and archive an existing signed document
with Tvarka ATK API
Run the long-term-validation chain over a signed document.
- Advisory validation - returns the qualification level, nothing to download.
- Add qualified timestamps to untimestamped XAdES signatures.
- Upgrade a PAdES B-T signature to PAdES B-LT for long-term validation.
- Retrieve the upgraded container with the one-off download token.
What you'll need to have ready
- document: Base64 container bytes, or use documentRef against an allow-listed host.
- format
- idempotencyKeyValidate: 1-255 visible characters. Stable per logical operation, NOT per attempt.
- idempotencyKeyTimestamp
- idempotencyKeyArchive
