For real-time integration with Salesforce, what is a key risk when using multiple integration users for SOAP API access?

When considering real-time integration with Salesforce, using multiple integration users for SOAP API access introduces the risk of exceeding user login limits. Salesforce imposes a restriction on the number of concurrent logins per user. Each integration user consumes a session, and if there are multiple integrations attempting to log in simultaneously, it can quickly lead to maxing out these login limits.

This can hinder a reliable integration process because as sessions are maximized, further API requests from those users will be rejected, leading to failures in real-time data synchronization and updates. Consequently, it is crucial to manage integration users wisely, ensuring that the number of concurrent sessions remains within Salesforce's limits to maintain seamless communication and functionality between systems.

While other risks such as data inconsistency and data loads exist, the specific concern with multiple integration users primarily aligns with the issue of login limits, impacting the effectiveness and reliability of the integration.
