Enhanced Messaging Channel Outbound Conversations

Introduction : 

Outbound Conversation in Enhanced Messaging Channels plays a vital role in communicating with your end users. 

Enhanced channels support 4000 TriggeredOutbound conversations/sessions per org  at any given point of time i.e there can be max 4000 TriggeredOutbound conversations/sessions per org at any given point of time.


What happens if the above Limit is reached and how will I get notified ?

You will receive a warning message via email from Salesforce Support :  

We have detected a significant increase in API usage on your org 00D50000000xXXX, over the last three hours. To avoid disruptions, could you please reduce the volume of outbound calls? Be advised that continued high usage may result Too many request errors. ...... 

When you reach the outbound conversation limit, the TriggeredOutbound messages are retried after every 10 minute interval i.e If the limit is reached, the message is enqueued and retried after every 10 minute interval.

Will this Impact my Billing on number of messaging sessions ?

Starting October 2nd '2024, you will be NOT be charged on retried sessions, however this will not apply to the extra sessions 
which were created before this date. 
From now on, same messaging session Id will be used from start till the end i.e only 1 messaging session would be visible at the end of all retries i.e you will be billed only on first messaging session instead of all the next retried sessions (Whatsapp and SMS)
