Sending Messages

Use this method to send messages to your clients via edna API.

You can test sending messages to a test phone number using edna API for the WhatsApp channel without having to register your channel first. To do that, go the the Testing tab on the Integration page.

If you want to test sending messages, keep in mind that we check for duplicates in SMS and IM. You cannot send a duplicate message within 20 minutes. Duplicate messages will be canceled.

If you have two WhatsApp templates registered with the same content, differing only in the Track clicks on link buttons parameter, we don’t recommend sending messages with such content via the API. Use your personal edna Pulse account to send. Otherwise, we cannot guarantee the correct display of link button click statistics.

schedule Method

A completed request using the schedule method results in a message that is sent to the messenger according to the parameters specified in the request body. If the request is successful, the server returns code 200 with a JSON object detailing the message identifier and its sending status. If the request fails, the server returns a response with an error code. Read more about error codes.

URL

To send a message, a POST request is sent to the following URL address: https://app.edna.io/api/cascade/schedule

Request Format

A JSON object is passed in the request body with all the cascade and message parameters. These parameters depend on the message type and its contents.

Request Example

This is an example of the body of a request for the following cascade. First, a message is sent to the client via the push channel, then a WhatsApp message is sent, and finally a text is sent via an SMS channel.
