High volume accounts
Accounts with high volume of simultaneous messages need more complex infrastructure to allow for seamless process of these messages. To increment an account's infrastructure, we can add more cores (or shards), which increases its capacity of processing higher messages simultaneously. Each extra core has a specific price.
Please note that the standard setting does not impede messages from being sent or received above its capacity - these messages will only take longer to arrive.

Webhook response

For the messages to be sent and received without delays, it is important to check how long it takes for your webhook to respond to requests. For responses above 80 milliseconds, there could be delays unrelated to 360dialog's structure.
If you can’t decrease the response time of your webhook but is experiencing issues, please get in touch with our support team.
Please use the following table to understand the number of cores recommended according to the volume of messages of this account.

To request an account upgrade, please get in touch with your main point of contact or file a ticket with our support team.
