WHMCS Profile custom field not taking data input via API

[Samar]

Hi there,

 

I was trying to create an api that updates the customfields of WHMCS. Our api backend is in golang using the echo framework. This is how I am trying to make the request

func updateShowOnboard(c echo.Context) error {

                var customFieldsArray []*CustomFields

                customField := &CustomFields{}

                customField.id = 3

                customField.value = "panelPassword"

                customFieldsArray = append(customFieldsArray, customField)

                customField1 := &CustomFields{}

                customField1.id = 7

                customField1.value = "howdidyoufindus"

                customFieldsArray = append(customFieldsArray, customField1)

                customField2 := &CustomFields{}

                customField2.id = 8

                customField2.value = "gstinhere"

                customFieldsArray = append(customFieldsArray, customField2)

                customField3 := &CustomFields{}

                customField3.id = 11

                customField3.value = "No"

                customFieldsArray = append(customFieldsArray, customField3)

                finalcustomfieldArray, err8 := json.Marshal(customFieldsArray)

                if err8 != nil {

                                return c.JSON(http.StatusBadRequest, errorMsg(err8))

                }



                url := os.Getenv("WHMCS_ENDPOINT")

                method := "POST"

                payload := &bytes.Buffer{}

                writer := multipart.NewWriter(payload)

                _ = writer.WriteField("username", os.Getenv("WHMCS_IDENTIFIER"))

                _ = writer.WriteField("password", os.Getenv("WHMCS_SECRET"))

                _ = writer.WriteField("clientid", "490")

                _ = writer.WriteField("customfields", string(finalcustomfieldArray))

                _ = writer.WriteField("responsetype", "json")

                _ = writer.WriteField("action", "UpdateClient")

                err1 := writer.Close()

                if err1 != nil {

                                return c.JSON(http.StatusBadRequest, errorMsg(err1))

                }



                client := &http.Client{}

                req, err2 := http.NewRequest(method, url, payload)



                if err2 != nil {

                                return c.JSON(http.StatusBadRequest, errorMsg(err2))

                }



                req.Header.Set("Content-Type", writer.FormDataContentType())

                res, err3 := client.Do(req)

                if err3 != nil {

                                return c.JSON(http.StatusBadRequest, errorMsg(err3))

                }



                defer res.Body.Close()

                body, err4 := io.ReadAll(res.Body)

                if err4 != nil {

                                return c.JSON(http.StatusBadRequest, errorMsg(err4))

                }



                m := map[string]string{}

                json.Unmarshal(body, &m)

                if m["result"] != "success" {

                                return c.JSON(http.StatusBadRequest, errorJSON{"Some error occured"})

                }

                return c.JSON(http.StatusOK, m)

}

 

as you can see that I am creating an array and appending customfields object with id and value to it, later I am converting it into json and converting the json to a string value and passing it to the customfields field in the payload. I get success message from the api but the values don’t change.

 

If you could point me to right direction that would be immensely helpful thanks.
