I'm trying to call a method which do an api call. But I'm getting an error because this method get call through the process ran by batch and this is getting schedule from trigger. So even if i directly call the API calling method it gives me an error 'Callout from triggers are currently not supported'. And when I call future method then it says future method cannot be called from batch.
Please help in this.Thank you.
The two errors you are receiving are both correct.
Callout from triggers are currently not supported
This is accurate; you cannot make callouts directly from triggers.
future method cannot be called from batch.
This is also accurate. As you'll see in the Batch Apex documentation,
To use a callout in batch Apex, specify Database.AllowsCallouts in the class definition. For example:
global class SearchAndReplace implements Database.Batchable<sObject>,
Database.AllowsCallouts{
}
The scheduler aspect is irrelevant to both errors, although scheduling a batch from a trigger is inherently a bit risky unless you can include very careful logic to avoid scheduling the batch repeatedly.
