The record

Purpose: The Envelope API lets developers create envelopes, add documents and signers, set signer authentication requirements, and activate signature flows.
API format: The Envelope API uses JSON:API formatting for requests and responses.
Webhooks: Webhooks send HTTP POST notifications to a registered URL when a signature event occurs.
Sandbox: The integration page describes an unlimited, free sandbox for testing integrations before launch.
Billing basis: The integration page says customers pay for documents finalized by all signers, rather than documents merely sent.
Integrations: The maker lists API, Zapier, Salesforce, and TOTVS as ways to connect Clicksign with business systems.
API availability: The integrations FAQ says API access is available on all plans, while API integrations generally require development and technical support.
Security certifications: Clicksign says it holds ISO 27001 and ISO 27701 certifications for information security and privacy.
Security practices: The security page describes least-privilege access controls, periodic vulnerability testing and risk assessments, backups, and annual independent audits.
Hosting and encryption: The homepage states that Clicksign uses AWS Multi-AZ infrastructure, TLS 1.3 in transit, and AES-256 at rest.
Legal framework: The maker says its electronic signatures comply with Brazilian Provisional Measure 2.200-2/2001 and Law 14.063/2020.
Support: The API documentation links users to Clicksign support, and the pricing page lists priority support for the Advanced plan.
Intended users: The maker describes API integrations as suited to more complex scenarios and says they generally require development.
