What RabbitSign is
RabbitSign handles electronic signature requests for PDF documents through web and API access. Manual signing is free and supports unlimited signature requests and templates, with audit trails and shareable template links. Creators can place signature, initials, text, date, and checkbox fields, choose a signing order, and copy other parties on completed documents. Batch Send can process up to 200 requests at once, with each request tailored using a CSV file. Its Developer API supports programmatic requests, webhooks, up to three API keys per account, and API logs. Signed documents include an audit trail, and RabbitSign records document hashes on an append-only ledger as proof of existence. The maker states that it meets SOC 2 Type II and ISO 27001:2022 requirements; HIPAA-compliant signing is available when an account accepts its BAA. Documents are encrypted at rest, and site traffic uses HTTPS and TLS. RabbitSign has no mobile app, but signing works in a phone browser. Integrations with Zapier, Salesforce, and HubSpot are under development.
