In Salesforce a 'callout' is any https call that accesses an external URL -- some other webservice or website. A 'callin' would be the opposite -- some external web service or application using the Salesforce API to access Salesforce data.

Simply so, what is API callout?

An HTTP callout is code that you write within Salesforce to (generally) call out to an external API over HTTP. REST and SOAP are types of APIs. So, you could make a callout to an external SOAP API or a REST API.

Also Know, how many callouts we can call in batch apex? It's per each call of execute() in the batch, so for each "batch", you can call up to 10 HTTP callouts. If the callout can handle multiple records at a time, do so, and batch up to 10 callouts per batch, otherwise, set the batch scope to 1, so each apex batch handles one record at a time.

Also question is, can a trigger make a call to Apex callout method?

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.

You cannot use static variables to return a value from a future method to the synchronous code that called it.
