+### Fields

+#### Get Field by Id
+
+```go
+import (
+  "context"
+  "fmt"
+  "github.com/StevanFreeborn/onspring-api-sdk-go/onspring"
+)
+
+client := onspring.NewClient("your-api-key")

+
+#### Get Fields by App
+
+##### Retrieve a single page
+
+```go
+import (
+  "context"
+  "fmt"
+  "github.com/StevanFreeborn/onspring-api-sdk-go/onspring"
+)
+
+client := onspring.NewClient("your-api-key")

+}
+```
+
+##### Retrieve all pages
+
+```go
+import (
+  "context"
+  "fmt"
+  "github.com/StevanFreeborn/onspring-api-sdk-go/onspring"
+)
+
+client := onspring.NewClient("your-api-key")

+    break
+  }
+  fmt.Printf("Retrieved Field: %+v\n", field)
+}
+```
+
+#### Get Fields by Batch
+
+```go
+import (
+  "context"
+  "fmt"
+  "github.com/StevanFreeborn/onspring-api-sdk-go/onspring"
+)
+
+client := onspring.NewClient("your-api-key")
