Send a question

Making a request to Conversations is a bit different from making a regular Send SMS request. The from parameter will not be used with Conversations, as the sender number will be added automatically.


For each country where you have conversations activated, you have a limit on the maximum number of active conversations(default is 3) at the same time with any one recipient. Contact our support if you need to increase this.


POST https://api.46elks.com/a1/conversations

Optional request parameters

Parameter Example Description

lifetime lifetime=2h Default is that a conversation is closed within 16 hours. That time window is adjustable down to 1h or up to 72h with lifetime parameter.
delay delay=allowed Delay is used in order to be able to "queue" questions if you have too many active conversations with the recipient. Ensures that once one conversation is closed the next question will be sent out.
