Only applicable for fields with deterministic tokenization.Note: This endpoint doesn't insert records—it returns tokens for existing values. To insert records and tokenize that new record's values, see Insert Record and the tokenization parameter. Reference: https://fern-docs.skyflow.dev/api/data/tokens/tokenize ## Authentication - `Authorization` header (bearer token, required) — Bearer authentication of the form `Bearer `, where token is your auth token. ## Servers - `https://%7B%7Bvault_url_identifier%7D%7D.vault.skyflowapis.com` (Production, default) - `https://%7B%7Bvault_url_identifier%7D%7D.vault.skyflowapis-preview.com` (Sandbox) ## Request ### Path parameters - `vaultID` (string, required) — ID of the vault. ### Body (application/json) This endpoint expects a tokenize_payload. - `tokenizationParameters` (list of tokenize_record_request, required) — Tokenization details. ## Response ### 200 A successful response. - `records` (list of tokenize_record_response, optional) — Tokens corresponding to the specified values. ## Errors ### 400 Bad Request Error Returned when the request doesn't match the schema, such as not including required fields. - `error` (ErrorResponseError, required) ### 401 Unauthorized Error Returned when the request doesn't match the schema, such as not including required fields. - `string` ### 404 Not Found Error Returned when the resource doesn't exist. - `error` (ErrorResponseError, required) ### 500 Internal Server Error An unexpected error response. - `error` (ErrorResponseError, required) ## Types ### tokenize_record_request - Column group: Column group - Table and column: Table and column ### tokenize_record_response - `token` (string, optional) — Token corresponding to a value. ### ErrorResponseError - `grpc_code` (integer, required) — gRPC status codes. See https://grpc.io/docs/guides/status-codes. - `http_code` (integer, required) — HTTP status codes. See https://developer.mozilla.org/en-US/docs/Web/HTTP/Status. - `http_status` (string, required) — HTTP status message. - `message` (string, required) - `details` (list of map from string to any, optional) ### Column group - `value` (string, required) — Existing value to return a token for. - `columnGroup` (string, required) — Name of the column group that the value belongs to. ### Table and column - `value` (string, required) — Existing value to return a token for. - `table` (string, required) — Name of the table that the value belongs to. - `column` (string, required) — Name of the column that the value belongs to. ## Examples **Request** ```json { "tokenizationParameters": [ { "value": "26/02/2001", "columnGroup": "persons_cg" } ] } ``` **Response** ```json { "records": [ { "token": "04/75/6955" } ] } ``` **SDK Code** ```python import requests url = "https://{{vault_url_identifier}}.vault.skyflowapis.com/v1/vaults/d4410ea0-1d83-473c-a09a-24c6b03096d4/tokenize" payload = { "tokenizationParameters": [ { "value": "26/02/2001", "columnGroup": "persons_cg" } ] } headers = { "Authorization": "Bearer ", "Content-Type": "application/json" } response = requests.post(url, json=payload, headers=headers) print(response.json()) ``` ```javascript const url = 'https://{{vault_url_identifier}}.vault.skyflowapis.com/v1/vaults/d4410ea0-1d83-473c-a09a-24c6b03096d4/tokenize'; const options = { method: 'POST', headers: {Authorization: 'Bearer ', 'Content-Type': 'application/json'}, body: '{"tokenizationParameters":[{"value":"26/02/2001","columnGroup":"persons_cg"}]}' }; try { const response = await fetch(url, options); const data = await response.json(); console.log(data); } catch (error) { console.error(error); } ``` ```go package main import ( "fmt" "strings" "net/http" "io" ) func main() { url := "https://{{vault_url_identifier}}.vault.skyflowapis.com/v1/vaults/d4410ea0-1d83-473c-a09a-24c6b03096d4/tokenize" payload := strings.NewReader("{\n \"tokenizationParameters\": [\n {\n \"value\": \"26/02/2001\",\n \"columnGroup\": \"persons_cg\"\n }\n ]\n}") req, _ := http.NewRequest("POST", url, payload) req.Header.Add("Authorization", "Bearer ") req.Header.Add("Content-Type", "application/json") res, _ := http.DefaultClient.Do(req) defer res.Body.Close() body, _ := io.ReadAll(res.Body) fmt.Println(res) fmt.Println(string(body)) } ``` ```ruby require 'uri' require 'net/http' url = URI("https://{{vault_url_identifier}}.vault.skyflowapis.com/v1/vaults/d4410ea0-1d83-473c-a09a-24c6b03096d4/tokenize") http = Net::HTTP.new(url.host, url.port) http.use_ssl = true request = Net::HTTP::Post.new(url) request["Authorization"] = 'Bearer ' request["Content-Type"] = 'application/json' request.body = "{\n \"tokenizationParameters\": [\n {\n \"value\": \"26/02/2001\",\n \"columnGroup\": \"persons_cg\"\n }\n ]\n}" response = http.request(request) puts response.read_body ``` ```java import com.mashape.unirest.http.HttpResponse; import com.mashape.unirest.http.Unirest; HttpResponse response = Unirest.post("https://{{vault_url_identifier}}.vault.skyflowapis.com/v1/vaults/d4410ea0-1d83-473c-a09a-24c6b03096d4/tokenize") .header("Authorization", "Bearer ") .header("Content-Type", "application/json") .body("{\n \"tokenizationParameters\": [\n {\n \"value\": \"26/02/2001\",\n \"columnGroup\": \"persons_cg\"\n }\n ]\n}") .asString(); ``` ```php request('POST', 'https://{{vault_url_identifier}}.vault.skyflowapis.com/v1/vaults/d4410ea0-1d83-473c-a09a-24c6b03096d4/tokenize', [ 'body' => '{ "tokenizationParameters": [ { "value": "26/02/2001", "columnGroup": "persons_cg" } ] }', 'headers' => [ 'Authorization' => 'Bearer ', 'Content-Type' => 'application/json', ], ]); echo $response->getBody(); ``` ```csharp using RestSharp; var client = new RestClient("https://{{vault_url_identifier}}.vault.skyflowapis.com/v1/vaults/d4410ea0-1d83-473c-a09a-24c6b03096d4/tokenize"); var request = new RestRequest(Method.POST); request.AddHeader("Authorization", "Bearer "); request.AddHeader("Content-Type", "application/json"); request.AddParameter("application/json", "{\n \"tokenizationParameters\": [\n {\n \"value\": \"26/02/2001\",\n \"columnGroup\": \"persons_cg\"\n }\n ]\n}", ParameterType.RequestBody); IRestResponse response = client.Execute(request); ``` ```swift import Foundation let headers = [ "Authorization": "Bearer ", "Content-Type": "application/json" ] let parameters = ["tokenizationParameters": [ [ "value": "26/02/2001", "columnGroup": "persons_cg" ] ]] as [String : Any] let postData = JSONSerialization.data(withJSONObject: parameters, options: []) let request = NSMutableURLRequest(url: NSURL(string: "https://{{vault_url_identifier}}.vault.skyflowapis.com/v1/vaults/d4410ea0-1d83-473c-a09a-24c6b03096d4/tokenize")!
