Retrofit Sending Json

I need to send a Json to a payment gateway through Retrofit. I really do not know what I have badly tested postman and everything works well. when trying to adapt with retrofit I o

Solution 1:

You don't need to mention that:

@Headers({
        "Accept: application/json",
        "Content-Type: application/json"
})

So remove this from your code.

test is boolean in your postman request but here you are passing as string so change following:

JsonObjectobjMerchant=newJsonObject();
    objMerchant.addProperty("apiLogin", "XXXXXXXXXXX");
    objMerchant.addProperty("apiKey","XXXXXXXXXXXXXX");

    JsonObjectobjPing=newJsonObject();
    objPing.addProperty("test", "false");
    objPing.addProperty("language","es");
    objPing.addProperty("command","PING");
    objPing.add("merchant",objMerchant);

to:

JsonObjectobjMerchant=newJsonObject();
    objMerchant.addProperty("apiLogin", "XXXXXXXXXXX");
    objMerchant.addProperty("apiKey","XXXXXXXXXXXXXX");

    JsonObjectobjPing=newJsonObject();
    objPing.addProperty("test", false);
    objPing.addProperty("language","es");
    objPing.addProperty("command","PING");
    objPing.add("merchant",objMerchant);

Test attribute is boolean in your postman request but here you were passing as string.

Solution 2:

Why there's no endpoint in @POST("./")?

Basically BASE_URL should be https://api.payulatam.com/ and your POST endpoint should be

@POST("payments-api/4.0/service.cgi/")

Besides, why are you creating request body manually? You can use a POJO class to serialize the request and I think it will be easier to handle that way. For example,

public class Request{ @SerializedName("language") public String language; //you can use private as well }

and to create the request,

Request request = new Request(); request.language = "es";

So in your interface, put it this way:

Call<Ping> sendPing(@Body Request request);

Can you try this and see?

Updated request object from postman request:

publicclassRequest{@SerializedName("test")public boolean test;

    @SerializedName("language")public String language;

    @SerializedName("command")public String command;

    @SerializedName("merchant")public Merchant merchant;

    publicclassMerchant{
        @SerializedName("apiLogin")public String apiLogin;

        @SerializedName("apiKey")public String apiKey;
    }
}
