Call future method in trigger

by Publisher
Yes, you can call, Create Apex Handler class and create a future mathod. Same method you can call from trigger. A future method runs in the background, asynchronously. You can call a future method for executing long-running operations, such ascallouts to external Web services or any operation you’d like to run in its own thread, on its own time. But, callouts cannot be made from apex triggers as that restricts database transaction until the callout is completed and the time limit for this is up to 120 seconds. The only way to execute a callout from a trigger is to run it asynchronously and this can be achieved by executing a method with the @future method. Future methods execute asynchronously i.e. one does not need to wait for a response. You can call a future method for executing long-running operations, such as callouts to external Web services or any operation you’d like to run in its own thread, on its own time. You can also use future methods to isolate DML operations on different sObject types to prevent the mixed DML error.

If you are making callouts from a trigger or after performing a DML operation, you must use a future or queueable method. A callout in a trigger would hold the database connection open for the lifetime of the callout and that is a "no-no" in a multitenant environment. Yes, we can call future method from a trigger. Only thing is, future methods are called asynchronously, meaning the thread is run with separate resources and other operations can not be blocked till Future method completes its processing. No. triggers require a known execution time since the rest of the record update sequence is on hold until a trigger exits. You have to put the @future in an apex class -- which you can call from a trigger. However, you have to make sure the trigger code, workflow rules, and assignment rules do not depend on the results of the @future. Hi Markus, Check if UserInfo.getUserId() getting value in your class as its a future method. If its not returning any value pass current user ID from trigger to future method. You cannot call a method annotated with future from a method that also has the future annotation. Nor can you call a trigger from an annotated method that calls another annotated method. If you do not have dependency between f1 & f2, you can call both methods one by one from original class. 1) Create a new field in respective object and update the value in future calls method and check the created field in trigger either the value is updated or not. 2) Use a static variable to store the state of the trigger processing or not (true/false)

Calling Future methods from triggers: We cannot call external web services synchronously from triggers because calling a web service synchronously from triggers will open the connection for the lifetime of the callout However, we can call the web service by using future methods i.e. asynchronously. Write a callout in a class using the future If you are making callouts from a trigger or after performing a DML operation, you must use a future or queueable method. A callout in a trigger would hold the database connection open for the lifetime of the callout and that is a "no-no" in a multitenant environment.

Future methods can’t be used in Visualforce controllers in getMethodName(), setMethodName(), nor in the constructor. You can’t call a future method from a future method. Nor can you invoke a trigger that calls a future method while running a future method.
