__sandra__ Apex callouts design
I would like to know what are the main differences between :
synchronous callouts and asychronous callouts
callouts in trigger, in batch and in a VF contoller
because I want to design a solution for the following requirement and I really dont khow what would be the appropried design :
Before inserting a new record for a cutom object, I want to do many synchronous callouts to gather some information, and depending on these information I have to update some of my record's fields before inserting it.
I have thought about making this in a before insert trigger, but it seems that triggers do not support synchronous callouts.
Thank you!
1. Write callout in a apex class (@future(callouts=true))...
2. Call the future method in trigger to get information from other server.
3. Use before trigger to populate the field before the record is inserted..
Thank you, but using an asynchronous call in a trigger means that the trigger does not stop until the callout response is received.
So can the record be inserted before getting the callout response?
Because I have to do some changes on the record fields based on the callout response before inserting the record.
Thank you!
