autosignly

Python client for the Autosignly API - eIDAS electronic signatures and document workflows.

Not published yet. This package is being built. Install from source for now.

Install

pip install autosignly

Requires Python 3.10 or newer.

Quickstart

from autosignly import AutosignlyClient, Signer

with AutosignlyClient(api_key="api_key_...", api_secret="api_sct_...") as client:
    document_id = client.upload_and_sign(
        pdf=open("contract.pdf", "rb").read(),
        document_name="Consulting agreement",
        signers=[
            Signer(
                first_name="Anna",
                last_name="Nowak",
                email="anna@example.com",
                country="PL",
            )
        ],
    )
    print(document_id)

The key and secret decide which environment you are working in. Every environment, production or sandbox, has its own pair, so pointing a script at the sandbox is a matter of swapping credentials.

The secret must stay on your server. It must never be shipped to a browser or a mobile app.

Reading documents

document = client.get_document(document_id)
print(document.status, [s.email for s in document.signers])

for summary in client.iter_documents(status="SIGNED"):
    print(summary.id, summary.name)

Downloading the file

A document carries a short-lived link to its file. The link expires, so fetch the document again for a fresh one rather than storing it.

document = client.get_document(document_id)
print(document.file_url)

pdf = client.download_document(document_id)
open("signed.pdf", "wb").write(pdf)

A document that is still being signed can be downloaded as well - it then carries only the signatures collected so far.

Tags

tag = client.create_tag("contracts")
client.set_document_tags(document_id, tag_ids=[tag.id], names=["2026"])

Setting tags replaces the whole set: tags left out are removed, and names that do not exist yet are added to the company tag pool.

Verifying webhooks

Autosignly signs every webhook delivery. Check the signature against the raw request body, before parsing it - re-serialising the JSON changes the bytes and the signature will not match.

from autosignly import webhooks

webhooks.verify(request.body, request.headers["X-Webhook-Signature"], webhook_key)

verify raises InvalidSignatureError on a mismatch; webhooks.is_valid(...) returns a boolean instead.

Errors

Every failure raises a subclass of AutosignlyError carrying the HTTP status and the error type returned by the API.

from autosignly import AutosignlyError, NotFoundError

try:
    client.get_document("does-not-exist")
except NotFoundError:
    ...
except AutosignlyError as error:
    print(error.status_code, error.error_type, error.error_id)

Connection problems and server errors are retried automatically, with an exponential backoff and jitter. Client errors are not retried, since repeating a rejected request cannot change its outcome.

Rate limits are retried too, honouring the delay the API asks for. When that delay is longer than a minute the call fails instead of blocking your thread, and RateLimitError.retry_after tells you how long to wait.

The client does not implement a circuit breaker. It runs inside your process, on calls you asked for, so refusing to even attempt one would be surprising - and your own infrastructure is the right place for that policy. Pass your own http_client if you want to add one.
