Libraries

Right now we have not yet released any API wrappers, but we plan to do so in the near future. Send an email to api@forwardemail.net if you would like to be notified when a particular programming language's API wrapper is released. In the meanwhile, you can use these recommended HTTP request libraries in your application, or simply use curl as in the below examples.

Language	Library
Ruby	Faraday
Python	requests
Java	OkHttp
PHP	guzzle
JavaScript	superagent
Node.js	superagent
Go	net/http
.NET	RestSharp

Base URI

The current HTTP base URI path is: https://api.forwardemail.net. The legacy HTTP base URI path of https://forwardemail.net:4000 will be deprecated on January 1, 2021.

Authentication

All endpoints require your free API key 🎉 to be set as the "username" value of the request's Basic Authorization header. Don't worry – examples are provided below for you if you're not sure what this is.

Errors

If any errors occur, the response body of the API request will contain a detailed error message. Besides having over ten years of experience writing API's and documenting them, were inspired by Stripe's beautiful API documentation when we crafted ours 😄.

Code	Name
200	OK
400	Bad Request
401	Unauthorized
403	Forbidden
404	Not Found
429	Too Many Requests
500	Internal Server Error
501	Not Implemented
502	Bad Gateway
503	Service Unavailable
504	Gateway Time-out

Localization

Our service is translated to over 25 different languages. All API response messages are translated to the last locale detected of the user making the API request. You can override this by passing a custom Accept-Language header. Feel free to try it out using the language drop-down at the bottom of this page.

Pagination
