File Upload API

Overview

The file upload API is an interface which can be used in your own applications to securely upload, manage and download files externally from this website.

API compatibility

This API will evolve over time when access to other data within the system is made available. However, none of the current endpoints or response values will change. You can write your integration code knowing that it will now be affected by future updates.

SSL/HTTPS recommended

We recommend SSL is used for all requests. You can require SSL by forcing it via your web server.

UTF-8 encoding

Every string passed to and from the API needs to be UTF-8 encoded.

HTTP Method

All methods are done using POST unless otherwise stated.

Date format

All date/times in the API are strings in the following format:

Y-m-d H:i:s

For example:

2023-06-02 14:30:27

API Path

All requests are sent to the follow API host: 

https://letsupload.io/api/v2/

Error handling

Errors are returned using standard HTTP error code syntax. Any additional information is included in the body of the return call, JSON-formatted.

Standard API errors

Error Code: Description:
400 Bad input parameter. Response error should show which one and why.
401 Bad or expired token. To fix, you should re-authenticate the user.
404 File not found at the provided path.
405 Request method not expected (generally should be GET or POST).
429 Maximum API request limit reached. Try to reduce the amount of requests or look at raising this via your web server configuration.
5xx Server error. See full list here.

Sample Error JSON Response

{
"status": "error",
"response": "Could not authenticate user. The username and password may be invalid or your account may be locked from too many failed logins.",
"_datetime": "2023-06-02 14:30:27"
}

Authentication

All requests to the API must be done with a valid access_token and account_id. The same 'access_token' can be used multiple times in the same session, so you shouldn't generate a new access_token for each request.

API Flow

Your external application should make API requests in the following order:

  • Request an access_token and account_id /authorize.

  • Example Response:

    {
"data": {
        "access_token": "lGoVSof0VRwq1Gaza8fODfIxQ4pu6j6rZvnRUCRPunfw4q5ezk3dALLqQbUWu1ntxKkrnbgSzwoDWtSwOVJoHuPxFKt9LRCjCXK081SIxgmuJe1y9KXQfMoVwS4iJHBm",
        "account_id": "158642"
},
"_status": "success",
"_datetime": "2023-06-02 14:30:27"
}
  • Request to the core API, such as getting user account details /account/info.
  • Make further API requests at any stage using the same access_token.
  • Once you've completed your requests you can clear the access_token. This is optional as these are also automatically cleared after 1 hour of no activity /disable_access_token.
  • Important: On each request you should check an error response. If the request resulted in an error, the "_status" will be "error" with more information in the "response" parameter.

/authorize

Provides an access_token and account_id to make further requests into the API.
