How To Retry The Callout 3 Times Based On The Response In APEX?
Last Updated July 28, 2024In this article we are going to discuss about how To Retry The Callout 3 Times Based On The Response In APEX? Usually, we should be prepared for these responses to accomplish the task expected after the callout smoothly.
Requirement Overview
- To have a callout 3 times based on defined response.
- Callout should not be done frequently based on responses (Considering the callout limit).
- At the time of specific responses, it should wait for a certain amount of time gap and then go for retry.
Solution Approach
You can approach this requirement using two apex classes .
To maintain the time interval between two callouts you can implement a Schedulable interface.
You can schedule the failure callout to retry after 5 minutes as continuous hitting can put your server flooded. (recommended)
And you are done, the below code gives a fair understanding of it.
Sample Code
Apex Class: RetryCallout
Apex Class: ScheduleCallout

Conclusion
By implementing the Schedulable interface, we are leveraging the scheduling mechanism for failure callout that helps us in fulfilling our requirements.
