I need to execute 4 webservices sequentially using a single button action. Here's the flow:
- The first webservice (A) should be executed.
- After A completes, its result should be passed as a parameter to the second webservice (B).
- Similarly, B’s result should be passed to C, and C's result to D.
Essentially, each webservice depends on the previous one's result. Is there a way to ensure the second webservice waits for the first to complete, and so on, all within the same button action?
What approaches or best practices can I use to handle this dependency and sequential execution?
