Hashmap.me Logo


Be aware, once a token is generated, it cannot be retrieved again. Make sure to write down your token to access your hashmap. If you lose it, you'll need to generate a new one.

What is Hashmap.me?

Hashmap.me is a streamlined service that lets you easily store and access your data records through HTTP, each linked to its own MongoDB collection, without the complexity of setting up a database.

x-api-key: [Your Hashmap Token]

Read Functionality

To retrieve all hashmap entry sets, perform a GET request to:

var myHeaders = new Headers();
myHeaders.append("x-api-key", "[YOUR-API-KEY]");
myHeaders.append("Content-Type", "application/json");

var raw = JSON.stringify({
  "key": "test",
  "value": "Value!"

var requestOptions = {
  method: 'PUT',
  headers: myHeaders,
  body: raw

fetch("https://hashmap.me/api/write", requestOptions)
