You can send a multipart/form-data request using an instance of the MultiPartFormDataContent class for a body or the submitFormWithBinaryData method. For more information please read the documentation.

Ktor 1.6.*

val client = HttpClient(OkHttp)

val response: String = client.post("https://httpbin.org/post") {
    body = MultiPartFormDataContent(parts = formData {
        append("page", 2)
        append("countPerPage", 20)
    })
}

println(response)

Ktor 2.*

val client = HttpClient(OkHttp)

val response = client.post("https://httpbin.org/post") {
    setBody(MultiPartFormDataContent(parts = formData {
        append("page", 2)
        append("countPerPage", 20)
    }))
}

println(response.bodyAsText())

I want to call an API with the body and send two parameters to this request in the android ktor client. how can I do this?

I wrote this code but it’s not working:

    override suspend fun getListOfAllCompanies(): ResponseModel<List<NetworkAllCompaniesModel>> =
        KtorModule.provideKtor().post(  HttpRoutes.GET_LIST_OF_ALL_COMPANIES) {
            body = Body1(page = 2, countPerPage = 20)
        }.body()

}

@Serializable
data class Body1(
    val page: Int,
    val countPerPage: Int,
)

This is my request:
