Steps
Create a Business API key in the Skribble admin area, yielding a username (key name) and api-key (secret); demo keys produce legally void test signatures, production keys are billed and legally valid.
Authenticate against the access-login endpoint sending the username and api-key to obtain a bearer access token for subsequent calls.
Create a signature request via the signature-requests endpoint, referencing the uploaded document and setting quality to QES (or AES_MINIMAL/AES, with SES currently gated behind contacting support).
Supply the required legislation parameter for QES/AES_MINIMAL quality (e.g. Swiss ZertES vs. EU eIDAS) since qualified signatures are tied to a specific legal regime.
Add signers to the request; QES signers complete Skribble's identity-verified signing flow backed by a Qualified Trust Service Provider partner recognized under both eIDAS and ZertES.
Poll status or use webhooks to track completion, then download the signed PDF, which embeds the QTSP-issued qualified certificate, once all signers finish.
Known gotchas
A quality of QES requires every signer on the request to complete QES — you cannot mix a QES requirement with AES-only signers; use AES_MINIMAL for a QES-preferred-with-AES-fallback flow instead.
legislation is mandatory for QES and AES_MINIMAL because Swiss ZertES and EU eIDAS QES rest on different legal frameworks — picking the wrong one can undermine the signature's intended legal effect.
SES-level signing is currently gated behind contacting Skribble support directly — it is not available out of the box via self-serve API keys.
