To set the

metadata_admin

field using the Ory Kratos Go SDK, you can use the

PatchIdentity

method. Based on the provided information and the Ory API documentation, here's how you can achieve this: The

dataMap

should be of type

map[string]interface{}

to represent the nested JSON structure you want to set for

metadata_admin

. Here's an example of how you can use the Go SDK to set the

metadata_admin

field:

go import (     "context"     "fmt"     "os"      client "<http://github.com/ory/client-go|github.com/ory/client-go>" )  func setMetadataAdmin(identityId string) error {     cfg := client.NewConfiguration()     cfg.Servers = client.ServerConfigurations{         {URL: fmt.Sprintf("<https://%s.projects.oryapis.com>", os.Getenv("ORY_PROJECT_SLUG"))},     }      ory := client.NewAPIClient(cfg)      dataMap := map[string]interface{}{         "foo": "bar",     }      patch := []client.JsonPatch{         {             Op:    "replace",             Path:  "/metadata_admin/signup",             Value: dataMap,         },     }      _, _, err := ory.IdentityApi.         PatchIdentity(context.Background(), identityId).         JsonPatch(patch).         Execute()      return err }

In this example,

dataMap

is of type

map[string]interface{}

, which allows you to create a nested structure that will be serialized to JSON when sent to the API. This approach will set the

metadata_admin

field to:

json {  "signup": {   "foo": "bar"  } }

The

PatchIdentity

method uses JSON Patch to update the identity. The "replace" operation will create the

signup

key in

metadata_admin

if it doesn't exist, or replace its value if it does. Remember to handle errors and set up proper authentication for the API client. [Ory API Reference](https://www.ory.sh/docs/reference/api) provides more details on the

PatchIdentity

method and its parameters.
