Asterisk Call ID override in ARI

Hi is there a way in ARI to generate a call id by self ? or get the call id as soon as we do channel create stage or channel create

What do you mean by “call id”? The SIP Call-ID?

If I understand your question correctly, yes.

Use the POST to /channels/{channelId} endpoint, and specify the channel ID yourself in {channelId}. This allows you to create channel ID in whatever format you desire.
