Apex HttpCallouts enable Salesforce to consume external APIs by sending HTTP requests to web services. These integrations function under strict governor limits to ensure platform stability and performance.

Core information
  • A single Apex transaction supports a maximum of 100 callouts to external HTTP or web service endpoints.
More details and nuances
  • Callouts fail if pending operations like DML statements exist in the transaction, requiring asynchronous methods like @future(callout=true) for trigger contexts where DML has already occurred.
