Nitro Software is a document productivity company (San Francisco, CA; part of the Nitro Productivity Platform) offering PDF editing, eSignature (Nitro Sign), and document intelligence. Nitro publishes a public developer platform of REST APIs at developers.gonitro.com covering two surfaces: a PDF Services / Document Intelligence Platform API (convert, extract, transform, redact, OCR, generate/fill forms) and the Nitro Sign API (envelopes, documents, participants, fields, sealing, audit trails, and signer signing URLs). The APIs use machine-to-machine OAuth 2.0 client-credentials with short-lived bearer JWTs, RFC 9457 problem+json errors, cursor pagination, asynchronous jobs with callbacks, and RFC 9421 signed Sign webhooks. API access requires a Nitro Sign Enterprise plan.
