Building a connector requires the use of the Orchestrator API. The following are the three primary resources that are available to help you during development.

1. [Orchestrator API Docs](https://docs.uipath.com/orchestrator/automation-cloud/latest/api-guide/read-me)
2. [Orchestrator API Swagger Doc](https://platform.uipath.com/techpartners/techpartners/swagger/ui/index)
3. [Orchestrator API Postman Collection](https://postman.uipath.rocks/)

Because the Orchestrator API includes many different operations, the table below is intended to provide further guidance on the specific operations to use for the more common connector functions.
