Add custom event

Custom events can be used to add metadata to your conversation. There are some restrictions when using custom events:

Event type must begin with custom:
Event type must not exceed 100 characters
Event type must contain ONLY alphanumeric, - and _ characters
Event body must not exceed 4096 bytes

Example

Ensure the following variables are set to your required values using any convenient method:

Key	Description
`CONVERSATION_ID`	The ID of the Conversation.
`MEMBER_ID`	The unique ID of the Member.

Prerequisites

You will need to use an existing Application that contains a Conversation in order to be able to add a custom event. See the Create Conversation code snippet for information on how to create an Application and some sample Conversations.

Write the code

Add the following to create-custom-event.sh:

# `from` is only required if you're using a JWT with a `sub` claim
curl -X "POST" "https://api.nexmo.com/beta/conversations/$CONVERSATION_ID/events" \
     -H 'Authorization: Bearer '$JWT\
     -H 'Content-Type: application/json' \
     -d $'{
  "type": "custom:YOUR_EVENT_NAME",
  "from": "$MEMBER_ID",
  "body": {
    "your": "data"
  }
}'
