In sqaureup application Aplication_name in oauth option there is a redirect url Which will redirect a given url with the QueryString code. While I'm hitting https://connect.squareup.com/oauth2/authorize?client_id=YOUR_CLIENT_ID this url in the browser then it will redirect me to a given url in oauth with attached code. And then to take a access_token you have to give a POST request to given url https://connect.squareup.com/oauth2/token with the body
{
"client_id": "YOUR_APPLICATION_ID",
"client_secret": "YOUR_APPLICATION_SECRET",
"code": "M-Q7k-N0Emx_3cBqwbVLTQ",
"redirect_uri": "YOUR_REDIRECT_URI"
}
I do it same and send By method POST to this url with json data but it will gives me the error:-
{
"message": "Not Authorized",
"type": "service.not_authorized"
}
The Golang Code I'm using for this is :-
func Token(c *gin.Context) {
code := c.Query("code") // code be something like:-sq0cgp-wLVQt5HOLfug6xiVdmCDCf
splitCode := strings.Split(code, "-")
token := models.PostToken{
ClientID: "YOUR_APPLICATION_ID",
ClientSecret: "YOUR_APPLICATION_SECRET",
Code: splitCode[1],
RedirectUri: c.Request.Host + c.Request.URL.RequestURI(),
}
bindData, err := json.Marshal(token)
if err != nil {
panic(err)
}
var jsonStr = []byte(string(bindData))
url := "https://connect.squareup.com/oauth2/token"
req, err := http.Post(url, "application/json", bytes.NewBuffer(jsonStr))
fmt.Println(req, err)
}
Models struct:-
type PostToken struct {
ClientID string `json:"client_id" bson:"client_id"`
ClientSecret string `json:"client_secret" bson:"client_secret"`
Code string `json:"code" bson:"code"`
RedirectUri string `json:"redirect_uri" bson:"redirect_uri"`
}
You have to do some points I mentioned:-
ClientSecret you have to use Oauth Application Secret key Which you will got from the application dashboard -> Oauth option.Code you don't have send the split code send simple string code value which your getting in the variable name code.Then you will got what you want :D.
