Sending compressed payloads

To send a gzip compressed payload to the EDI Core API, set the Content-Type header to the value of application/gzip. EDI Core only supports gzip compression.
Note that the maximum document size limit is applied after decompressing the content of the payload. If the decompressed payload of a given request is larger than the maximum document size limit, the EDI Core API will reject the request.
The following TypeScript example shows how to send a gzip compressed payload to the /translate endpoint.
import * as fs from "fs";
import axios from "axios";
import { gzipSync } from "zlib";

const rootURL = "https://edi-core.stedi.com/2021-06-05/translate";
const headers = {
  "Authorization": `Key ${API_KEY}`,
  "content-type": "application/gzip",
  "accept-encoding": "gzip",
const edi = fs.readFileSync(process.argv[2], "utf-8");

async function makeRequest(): Promise<void> {
  const request = {
    input: edi,
    input_format: "edi",
    output_format: "jedi@2.0",

  const response = await axios.request({
    method: "post",
    url: url,
    data: gzipSync(JSON.stringify(request)),
    headers: headers,

async function main() {
  try {
    await makeRequest();
  } catch (e) {
