Using GET instead of POST

It is possible GET requests to access the API if you can not use POST for security or technical reasons.

All calls to the 46elks API can be made with GET, just add /POST to the end of any API resource. For example, you can use both POST /SMS and GET /SMS/POST to send an SMS. When using GET all parameters need to be urlencoded query parameters.

Example

GET https://api.46elks.com/a1/sms/POST?to=+46701234567&from=ElkCo&message=Hello!
