HTTP SMS API Documentation


Ez Texting provides REST & HTTP Text Messaging APIs.

API calls can be made from nearly all popular programming languages. Through our API you can access many different features of the Ez Texting platform. Browse them below and check out the list of available APIs and their parameters. FYI: You must first open an Ez Texting account to use our APIs.

Looking for information about receiving text messages?
View the documentation for our two incoming message APIs.

Please note: While we will continue to support our HTTP API, this is a legacy product. Active development has moved to our REST API. As such, we encourage you to use our REST API. The REST API already offers new bulk sending and message scheduling options. No new features will be added to the HTTP API.

Sending SMS Messages

Description
Sends individual SMS text messages via the short code 313131 (393939 in Canada) or SMTP gateway. Accepts GET or POST requests.
Note: Our servers impose a limit on the number of simultaneous connections that you may make from your server to ours per second.  To avoid having your IP blocked, please do not attempt to make more than 2 simultaneous HTTP connections per second to our servers.  Please also make sure that you close each connection after opening one when making your HTTP request.  If you are running a multithreaded application please also be aware of the limit that is imposed. If your application exceeds this limit you may receive a rate limiting error, with the HTTP status code 503 in the header and your request will not be processed. If you believe you are being incorrectly rate limited please contact support.

If you are sending the same message to multiple recipients we strongly urge you to consider using our REST API, which allows you to pass a single message and an array of phone numbers to deliver in a single request.

If you decide to use the HTTP API, when sending multiple request we strongly suggest using the following logic in order to avoid this limitation:
1) Open Connection
2) Begin Loop
3) Make Request
4) Close Loop
5) Close Connection
