# Sepasoft > Sepasoft builds Manufacturing Execution System (MES) software that ships as modules for > the Inductive Automation Ignition platform. The suite covers OEE and downtime tracking, > track and trace, batch procedure control (ISA-88), SPC, settings and changeover, document > management, ERP integration through the Business Connector (B2MML / ISA-95) and an SAP > interface, plus SepaIQ for manufacturing analytics, machine learning and LLM features. ## What "the Sepasoft API" actually is Sepasoft operates no hosted, public API and issues no API keys. Its Web Services module turns the CUSTOMER'S OWN Ignition Gateway into a REST and SOAP endpoint - both provider and consumer. Endpoints are authored by the operator in the Ignition Designer and served from that gateway, so every base URL is deployment-specific: - REST: https://{ignition-gateway-host}:{port}/main/system/ws/rest/{resource_name} - REST (nested): https://{ignition-gateway-host}:{port}/main/system/ws/rest/{folder}/{resource_name} - SOAP: https://{ignition-gateway-host}:{port}/main/system/ws/soap/{resource_name} - WSDL: https://{ignition-gateway-host}:{port}/main/system/ws/soap/{resource_name}?wsdl Methods: GET, POST, PUT, DELETE. Response format: JSON or XML, chosen per endpoint. Auth on the provider side: HTTP Basic against an Ignition User Source, optionally scoped by required role(s). Missing credentials -> 401 + WWW-Authenticate; wrong credentials -> 403; no handler for the method -> 405; script error -> 500. Auth on the consumer side: Basic, Digest, NTLM, mutual TLS (JKS keystore/truststore), and OAuth 2.0 client credentials against an authorization server the operator runs. No OpenAPI, AsyncAPI, GraphQL SDL, Postman collection or JSON Schema is published by Sepasoft. The SOAP WSDL is generated at runtime, per endpoint, on the customer's gateway. ## Documentation - MES User Manual: https://docs.sepasoft.com/ - Web Services module: https://docs.sepasoft.com/articles/user-manual/web-services - RESTful Endpoints: https://docs.sepasoft.com/articles/user-manual/restful-endpoints - SOAP Endpoints: https://docs.sepasoft.com/articles/user-manual/soap-endpoints - RESTful Configuration (consumer): https://docs.sepasoft.com/articles/user-manual/restful-configuration - OAuth 2.0 client credentials for RESTful consumers: https://docs.sepasoft.com/articles/user-manual/configuring-oauth-client-credentials-for-restful-consumers - Consumers (SSL / keystore): https://docs.sepasoft.com/articles/user-manual/consumers - system.ws scripting functions: https://docs.sepasoft.com/articles/user-manual/system-ws - Business Connector and Web Services: https://docs.sepasoft.com/articles/user-manual/business-connector-and-web-services - Knowledge Base: https://docs.sepasoft.com/articles/knowledge-base/mes-3-0-knowledge-base Every docs article also serves a markdown twin: append `.md` to the article URL. ## Releases - Downloads and version matrix: https://www.sepasoft.com/downloads/ - MES 3.0 service pack release notes: https://docs.sepasoft.com/articles/release-notes-publication/service-pack-release-notes - MES 4.0 service pack release notes: https://docs.sepasoft.com/articles/release-notes-publication/mes-4-0-current-service-pack-sp-release-notes Current: 3.81.13 SP1 (Ignition 8.1) and 4.83.3 SP1 (Ignition 8.3), both 2026-07-31. ## Commercial - MES pricing: https://www.sepasoft.com/pricing-mes/ - SepaIQ pricing: https://www.sepasoft.com/pricing-sepaiq/ - Products: https://www.sepasoft.com/products/ - Web Services module: https://www.sepasoft.com/products/web-services/ - Business Connector Suite: https://www.sepasoft.com/products/sepasoft-business-connector/ - Terms of Use: https://www.sepasoft.com/terms-of-use/ - Privacy Policy: https://www.sepasoft.com/privacy-policy/ - Trust center (SOC 2, ISO/IEC 27001): https://trust.sepasoft.com/ Licensing is per module, per server or per physical production site - one-time list prices for the MES modules, annual subscription for SepaIQ.
