Dropbox Sign API vs Sertifi API

Dropbox Sign API lets developers add electronic signature workflows to their own websites and applications. Embedded request, signing, and template-management steps can appear in iFrames, with custom branding for senders and signers. Reusable templates can hold preloaded data for recurring signature processes. The service connects with Dropbox, Microsoft Word, Salesforce, Google Drive, HubSpot, Slack, and other CRM, storage, and productivity tools. Its listed security provisions include OAuth 2.0, 2FA, AES 256-bit encryption at rest, and non-editable audit trails that time-stamp document actions. Dropbox Sign lists SOC 2 Type II, ISO 27001, eIDAS, and GDPR compliance. Its signatures are legally binding in the United States, European Union, United Kingdom, and many other countries. SDKs are available for Python, Ruby, PHP, Java, NodeJS, and C#, and development help is available through documentation, the Help Center, and email support engineers. Senders and signers can use the service end-to-end in 22 languages. Free plans are listed; paid pricing starts at $75/mo. More than 500 requests per month requires contacting sales.

Sertifi API provides REST, SOAP, and Travel Company Authorizations paths for integrating Sertifi signing and payment workflows. REST documentation covers creating folders and documents, inviting signers, and adding payment requests; a REST key is obtained through a Customer Success Manager or support ticket. Sertifi’s e-signature service targets hospitality businesses and supports contracts, BEOs, HR paperwork, and other documents. Signers can work from any device and location, while templates, reminders, and payment requests support the workflow. Named integrations include Amadeus Delphi.fdc, Infor HMS and Sales & Catering, Oracle OPERA Cloud Service, Salesforce, and payment processors. The offering lists seven SDK languages, embedded signing, a workflow status API, 17 webhook event types, signed-file retrieval, and a sandbox. Sertifi states that connections use TLS 1.2, with SOC 2 Type 2 and ISO 27001 compliant facilities, PCI Level 1 validation, HIPAA compliance, and annual audits. Signed documents remain in its portal for one year; emailed PDFs remain available indefinitely.
