# Third party integration :no\_entry\_sign:Professional :white\_check\_mark:Premium :white\_check\_mark:Enterprise ## Connecting to third party web services Ultimo Business Integration is able to connect with third party web services. Both import and export connectors offer the possibility to send requests to a webservice url. By default, the request will be sent in a fixed Ultimo format. It is however possible to send data in a specified custom (xml or json) file format. This can be configured by our consultants. Ultimo Business Integration is also able to connect with web services that require a Expect: 100-continue header in the initial request. ### Authentication options The following authentication types are supported when connecting to third party web services: * Basic authentication * Ultimo only supports pre-emptive authentication; the Authorization header is directly send with the first request * [OAuth2.0](https://oauth.net/2/) * Ultimo offers support for grant types Authorization code, Password and Client credentials --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
