Call future from apex

When making a callout from a method, the method waits for the external service to send back the callout response before executing subsequent lines of code. Alternatively, you can place the callout code in an asynchronous method that’s annotated with @future(callout=true) or use Queueable Apex. This way, the callout runs on a separate thread, and the execution of the calling method isn’t blocked. *Low margins are a double edged sword, as lower margins mean you have higher leverage and therefore higher risk.

No more than 0 in batch and future contexts; 1 in queueable context method calls per Apex invocation Note Asynchronous calls, such as @future or executeBatch , called in a startTest , stopTest block, do not count against your limits for the number of queued jobs. Can we call a future method from batch Apex? No, We cannot call future methods directly from batch apex but we can call a  web service from batch class and that web service can call the @future method. Also, we can call the future method from finish method in the batch class. March 16, 2018 Without the annotation, the Web service callout is made from the same thread that is executing the Apex code, and no additional processing can occur until the callout is complete (synchronous processing). Methods with the future annotation must be static methods, and can only return a void type. No more than 50 method {Methods with the future annotation} calls per Apex invocation; The maximum number of future method invocations per a 24-hour period is 250,000 or the number of user licenses in your organization multiplied by 200, whichever is greater. This limit is for your entire org and is shared with all asynchronous Apex: Batch Apex, Queueable Apex, scheduled Apex, and future methods. Future methods execute asynchronously i.e. one does not need to wait for a response. The thing to keep in mind is, a future method can have native calls, as well as, they can make a call out to an external web service and hence, in order to enable the future method to allow callouts, an extra parameter “Callout=true” needs to be passed.

It limited to 50 future calls per Apex invocation, and there's an additional limit on the number
