Thisis my pseudo Code Android, API interface:

    @Headers({"Content-Type: multipart/form-data", "Authorization: F31daaw313415"})
    @POST("api/store/order")
    Call<List<PostCommandResponse>> setCommandeProduct(@FieldMap Map<String, Object> test);

            data.put("adress", RequestBody.create(MediaType.parse("multipart/form-data"),adresse));
            data.put("city",RequestBody.create(MediaType.parse("multipart/form-data"),city));

My suggestion would be to use the data model class something like below.

public class UserInfo {

@SerializedName("product_id")
@Expose
private Integer productId;
@SerializedName("address")
@Expose
private String address;
@SerializedName("city")
@Expose
private String city;
@SerializedName("zip")
@Expose
private String zip;
@SerializedName("first_name")
@Expose
private String firstName;
@SerializedName("last_name")
@Expose
private String lastName;

public Integer getProductId() {
return productId;
}

public void setProductId(Integer productId) {
this.productId = productId;
}

public String getAddress() {
return address;
}

public void setAddress(String address) {
this.address = address;
}

public String getCity() {
return city;
}

public void setCity(String city) {
this.city = city;
}

public String getZip() {
return zip;
}

public void setZip(String zip) {
this.zip = zip;
}

public String getFirstName() {
return firstName;
}

public void setFirstName(String firstName) {
this.firstName = firstName;
}

public String getLastName() {
return lastName;
}

public void setLastName(String lastName) {
this.lastName = lastName;
}

}

set the values in this model UserInfo and pass this to the API call something like below.

@Headers({"Content-Type: multipart/form-data", "Authorization: Bearer F31daaw313415"})
@POST("api/store/order")
Call<List<PostCommandResponse>> setCommandeProduct(@Body UserInfo test);

Just a small correction: also check if the adress or address is needed to be sent in JSON. adress is getting used in the JSON body image. Change accordingly.

Edit: you are sending the headers in the wrong format also.

It should be something like this.

@Headers({"Content-Type: multipart/form-data", "Authorization: Bearer F31daaw313415"})
