I have a scenario where i need to call a Remote Action which makes a callout in a loop until i get some results from the external service. Reason to call it in a loop is that if for some input service returns null, i need to increase input and call service again. I am getting this warning email :
Caused the following Apex resource warnings: Number of callouts: 80 out of 100
Should i do something to handle this warning ?
You could add limit handling, and check if the number of callouts already made is close to the limit. Once you are at the limit, you could log unsuccessful callouts, or show a nice message to the user. Alternatively, if no user should be involved, you could queue up a batch job to repeat these callouts until you get a valid response from the server.
Something like this after every call out:
if (Limits.getCallouts() == Limits.getLimitCallouts()) { // exit gracefully while adding a message to the page telling to try again, or queuing up a batch job with more call outs }
