What emSigner API is
emSigner API lets organizations send document-signing requests from their systems through REST API endpoints. The API covers user, workflow, and document management, and requests use JWT authentication. Each envelope can contain up to 10 documents with a combined file size of 25 MB. Billing is based on envelopes consumed and successful transactions in which all parties sign the included documents. The Professional API envelope plan costs $0.99, paid once; each envelope is valid for one year. Essential is listed at $1, paid once, while Professional has no listed price. A 30-day free trial is available, but there is no free plan. Signing options include Simple, Advanced, and Qualified Electronic Signatures. Workflows can place signature fields by coordinates or search text, and include signatories, reminders, PDF protection, and watermarks. Salesforce and SAP connectors are named. The API and Gateway are available in AWS-hosted cloud with multiple-region data residency, and on-premise deployment is also supported. The listed platforms are Android, API, iOS, self-hosted, and web.
