Copy or reference: where your product keeps the signature proof
· 4 min read
When a signature request completes, your product has a new thing to look after: the proof. One day an auditor, a customer or your own support team will ask for it, often months after the signer finished. So the integrating developer has to decide early how the backend treats that proof: copy it into your own storage as soon as the signature is done, or keep a reference and fetch it from IgniSign when someone asks. This post is about that choice.
