Connectors are the interface between a backend system and Simplifier to communicate with each other. They consist of at least one connector call.
| Connector | Addresses a specific backend system (like SAP, or Database, etc.) |
| Connector Call | Leads a connector into action and contains input and output parameters |
Connector Type |
Description |
| SOAP | Use the SOAP connector to access a Simple Object Access Protocol based on HTTP and XML Format. |
| REST | The REST (REpresentational State Transfer) connector is used for HTTP REST Services. The architecture uses standardized operations (GET, PUT, POST, DELETE) on web services. REST API is an alternative to other interfaces like SOAP. However, REST itself is neither protocol nor standard. |
| SQL | With the SQL (Structured Query Language) connector, SQL statements are executed in a database schema, to request or edit based databases. |
| OPC/UA | The OPC/UA (Open Platform Communications Unified Architecture) connector accesses to an OPC-UA server and performs READ/WRITE/SUBSCRIBE operations. |
| SAP RFC | The SAP RFC (SAP Remote Function Call) connector is based on standard JCo SAP RFC to call functions in remote systems. |
| MQTT | MQTT (Message Queuing Telemetry Transport) is an open message protocol for machine-to-machine communication (M2M) that allows telemetry data to be transmitted as messages between devices, despite high delays or limited networks. This connector acts as a client and can publish or subscribe messages from an MQTT server (broker). |
| Push | The Push connector sends push notifications over WebSockets directly to Simplifier Clients or Simplifier Browser Apps without using Google or Apple’s Cloud Services to support data protection and privacy. |
| CSV | Use the CSV (Comma-separated values) connector to read and/or write comma-separated files on a local file store. |
| OData V2 | OData (Open Data Protocol) is an open protocol based on HTTP for data access to enable CRUD operations. It enables the creation of REST-based data services to be published and edited by Web clients using simple HTTP messages. |
| Use the Email connector to send emails over SMTP (Simple Mail Transfer Protocol) with or without SSL Encryption. | |
| Proxy | The Proxy Connector allows the usage of any HTTP services that are not based on specific protocol architectures such as REST, SOAP or OData. |
