Commit file using REST API


I'm building a web based editor (in React) which needs to commit changes to our BitBucket repo. GET requests seem to working perfectly however the code below is returning a 415 error which I think relates to incorrect content/meta type..?

There's no mention of how to specify a meta type in the docs,

Is meta type the real problem here? or have I done something else wrong?

Can anyone help?


const url = new URL(`${workspace}/${repo}/src`);

const params = {
    access_token: query.access_token,
    message: encodeURIComponent("commit"),
    branch: branchName,
    [encodeURIComponent(path + '/start.json')]: "helloWorld"

Object.entries(params).forEach(([key, value]) => {
    url.searchParams.append(key, value)

fetch(url, { method: 'POST' }).then(handleResponse);

Here's the fix for anyone searching...


const url = new URL(`${workspace}${repo}src`);
url.searchParams.append('access_token', token);

const data = new URLSearchParams();
data.append('message', commitMsg);
data.append('branch', branchName);
data.append(path, fileContent);

const options = {
method: 'post',
headers: {
"Content-type": "application/x-www-form-urlencoded; charset=UTF-8"
body : data

fetch(url, options).then(
