Logic Apps custom connector with Cookie header

Question

Hi,

I am trying to call an api through a custom connector (Gateway enabled) through a logic app.

There are 2 custom connectors

1. The first one returns me a sessionID in the Set-cookie header response.
2. I am passing the sessionID as a Cookie header to the 2nd custom connector (the one where i have a problem). This seems to be not working as expected. I dont know if we can send the Cookie header or its not possible with gateway connectors.

I saw a few blogs that mentioned that sending Cookie headers to a custom connector doesnt work.

Please help.

Hi @Thakkar, Bunty ,

Welcome to Microsoft Q&A Platform. Thank you for the question.

It seems HTTP connectors do not use gateway so you cannot establish connection & custom connectors do not support Cookies. So I would suggest you to explore the Azure Function App to make the HTTP request with Cookies.

Also, you can check the similar discussion in below thread, and highlighting the points for your reference,

1. HTTP action does not support on-premise data gateway, so the hostname or ip could not be resolved because the HTTP action always talks to public network.
2. If you could use custom connector to connect to on-premise data gateway, you should not get the unresolvedhostname issue. However, the custom connector does not support Cookie authentication, that’s why you could not get it through.
3. One workaround is using application gateway to reverse proxy services and publish your on-premise server to public. It would act like an VPN and you could use HTTP action in logic app to establish connection.
4. Another workaround is trying to use Function App to make the HTTP request with Cookies
