HTTP response from endpoint

[Mag_ Tomer Harp]

Hello,

If there are 3 systems connected using HTTP(S)  like:

A-->B-->C

The problem is that if A received 200 from B , and B receive an HTTP error from C,  A will not be aware to it (This how HTTP works).

I know that there is a way to receive the HTTP response from the end point (so A will be aware to an error occur between B and C) but I forgot how it called.

You can have B passing the HTTO status to A incase it received (!200) from C.

Since your A and B are connected there shouldn't be any problem in this.

HTTP response is returned to the caller only.  There is a way to automatically pass it to the back, I just forgot how it called,

[RaghavSh]

Once you get the Http status as error in B, make outbound POST call to A.

You can update the HTTPs status in the required field/record on instance A.

This means I need to create an API in A to receive data from B. This I know...

but I remember that there is a way to do it with configuration only in B. 

The idea is to delay the HTTP response from B to A  until C responses. Then B should take the response it received from C and pass it to A.

so it means to sync the calls. 

I know there is a way to do it, I just forgot how,
