Externalize Parameters: how to fetch value dynamically

[Former Member]

Hi Experts

I have Timer start event(i harcoded payload for testing)to HCI to SFTP scenario where i want to put the receiver credential name dynamically from the incoming payload.

My incoming structure is:

<header>
<hedfield>sftpuser1</hedfield>
</header>
<invoices>
<invfieid1>testinv1</invfieid1>
<invfieid2>testinv2</invfieid2>
</invoices>
<images>
<imgfield2>SGkgdGhpcyBpcyBiYXNlIDY0IGVuY29kZWQ=</imgfield2>
</images>

and i want to pick the receiver credential name from <hedfield>sftpuser1</hedfield> of header field in the payload so i changed the below external parameter as follows.

Receiver channel external parameter

But everytime i set {{Receiver_credential_name_2}} as //header/hedfield it resets the value at runtime to my old saved credential that i used in past.

Am i not doing it the correct way. Please help.

Hi Morten

This is where you are suggesting camel parameters, but for private key alias and credentials i coudnt see anything matching hence a new question

Hi Naina,

I tried the way like you said. But it does not work. Could you provide more details,like the iFlow details, you create the new header in which component or script etc. ?

Thanks very much

Hi Naina,

In the externalized parameters tab there is a save button you should click on it in order to save the new value.

But I don't know if the value could accept XPath expressions or not.

Please let us know if you solve your problem.

Best regards,

Hi Amin

Directly it did not work, so i added the incoming payload first in header and then called header in externalized parameter:

added LoginID in header

called header in EP:
