How to obtain a response header value in a data stream action?

[arielgritti]

Hi community,

I'm configuring a data stream action in Flow Designer. I'm stuck in the "pagination step".

How can I obtain a response header value?

The scenario is:

In the REST step, the answer from the external system has a "token" to know if is there more data to retrieve. The response header is called "x-foundation-continuation" (see an extract of the JSON answer)

The FD step execution runtime is showing it:

I need to use this value to change to true/false the getNextPage (read-only) variable in the pagination step, but I can't get it.

In this step (pagination) the two available variables are: variables and pageResponse. I'm trying using pageResponse but it seems empty.

The option to obtain it from the Response Body doesn't cover the need here, because the value is coming in the Response Header. 

I tried to do it like this; it doesn't works too.

Any help is welcome.

Thanks,

Ariel

Following this article: https://hishowcase.service-now.com/kb?id=kb_article_view&sysparm_article=KB0756552

I found a potential solution/example of how to access the response_headers variable.

I'm testing it. First test, wrong 😞

Hi @Chuck Tomasi 

I'm sorry to bother you here. I saw your videos:

• IntegrationHub Data Stream for Import Data Source - Live Coding Happy Hour for 2021-01-15 (17:38 pagination)
• Data Stream Actions - Learn Integrations on the Now Platform

One of them is the example: 

totalCount = parseInt(pageResponse.responde_headers(['X-Total-Count']);

I have the same situation. In my case, the "token" to decide to get more data is in the response headers, but when I execute the action, it seems response_headers variable is empty.

Any idea?

Thanks,

Ariel

Hi @arielgritti 

The correct script is:

Line 5: var totalCount = parseInt(pageResponse.response_headers['X-Total-Count']);

 Best Regards

Hi @User279787 

I can see a typo in my code (I'll review it) "responde" instead of "response" (I don't know if it was a copy&paste issue when I created my community question) and the brackets and parenthesis use.

I'll check and let you know.

Thanks for your answer.
