## Good to know

The Exact API is very extensive, thus there are some extra tipps for working with the Exact Connector:

* The [documentation](https://start.exactonline.nl/docs/HlpRestAPIResources.aspx?SourceAction=10) is very important and it makes sense to use it, in parallel with the Connector Action
  * To find endpoints quickly, use the Endpoint Search field
  * There are almost always links to details for endpoints
  * `GET` and `POST` fields are not the same (fields are shown, by selecting a method at the top)
  * `!` means required field
* Many requests bodies are quite nested and often required fields and the nested structures need to be provided
* [Filtering works with OData Syntax](https://www.odata.org/documentation/odata-version-2-0/uri-conventions/) (don’t forget to set quotation marks); unfortunately there are no good examples in the documentation
* `POST` requests don't return response payload, instead a `GET` call needs to be made afterwards to get the actual data
* `POST` actions are not added in Locoia, as the format is quite custom, instead the POST Wildcard Action should be used
* In general there are lots of dependencies between entities
