Steps
Set up API keys or OAuth client credentials in the Proof developer dashboard and test against the sandbox environment first
Tag the document with notary signature/seal placement using document tagging (white-text tags or the tagging API) before creating the transaction
Call the create transaction endpoint on the Business API, attaching the tagged document(s) and specifying signer and notary details
Either let Proof email the signer an invitation, or retrieve the transaction access link via the API and deliver it through your own application
Register a Webhooks V2 endpoint to receive transaction status events (e.g., signing complete, notarized) instead of polling for status
After completion, call the document retrieval endpoints to download the notarized document and its notarization record/audit trail
Known gotchas
The Real Estate API is reserved solely for real-estate transactions (mortgage, refinance, title, HELOC); general business contract notarization must use the separate Business API
Documents need notary/signature fields explicitly tagged via document tagging before a transaction is created — untagged documents won't have valid notarial-act placement
The platform was rebranded from 'Notarize' to 'Proof'; older integration guides or support content referencing the 'Notarize API' may describe outdated endpoints or terminology, so verify against the current dev.proof.com docs
