How to change variables in request?

[raffinkira]

Hi experts:

The request content type is x-www-form-unlencoded. The form data name is 'aaa'.

I want to change the value of 'aaa' by using policy before the request goes to the target endpoint.

Which policy should I use? I have tried "Extract Varibles" but don't know how it works.

Anyone could help?

Regards,

Ming

Hi Ming,

You can use an AssignMessage policy or alternatively JavaScript policy to change the variables. So based on your use-case , you can combine an Extract Variable policy to read the data and Assign Message or JS to set the data.

Thanks and Best Regards,

I just want to change the existing parameter in request, so after trying I found only Assign Message is enough to work.

Thank you very much for your help.
