I want to extract “oqTW1ZbKqqCgz592nKKUnaGQd5_r”

I am not getting any request payload while printing in logs.

Hi Preethi, can you please try giving the pattern as given below and give it a go.

<PatternignoreCase="true">/activate/{token}</Pattern>

I have tried that too.

Two things.

  1. regarding your comment

I am not getting any request payload while printing in logs.

The extractVariables policy does not properly emit trace statements, when you use a variable prefix. This is a bug. It is being fixed, but may still affect your version.

  1. The ExtractVariables MAY actually be working. If you are judging the correctness of its operation by the Trace output, you may be misled. Check the results of the AssignMEssage to be sure.

As per the EV doc, if the basepath for your API Proxy is /user then you need to include /activate/{token} in the Pattern .

<Pattern ignoreCase="true">/activate/{token}</Pattern>

Can you send me a api bundle for this path variable extraction?
