Hi Experts,

I am trying to send POST request using HTTP connector. The Odata API required x-csrf-token to be sent as well. I could fetch token from previous GET request and trying to pass it to subsequent POST request. Though I could see it as input, API returns with a message 403 and CSRF token validation failed. The same works with POSTMAN. Please suggest.

Input :

Raw input :

Output

Unable to send x-csrf-token in POST request

Hi Guys, I'm new to power apps. I'm using custom connection to generate CSRF token. I managed to get 200 response but the x-csrf-token is not included in the Header respone. Appreciate if someone can help me. Big help!

Here is the screenshot of how you pass the cookie getting from the GET x-csrf-token call. Please accept this as a solution if it resolves your query.

1. Getting the csrf token
2. In Compose replacing the set-cookie value ',' with ';'.
3. POST call by sending the Cookie value.

Thanks, I have replace the commas to semicolon, but still I am getting the CSRF token validation failed error.
I am trying to connect to on-premise SAP System via data gateway and already did all the configuration but still unable to send cookies.

Yes, it has been resolved.
Modify this expression to yours "replace(outputs('Get_product')['headers']['Set-Cookie'],',',';')" to replace commas in your set-cookie.

Re: Unable to send x-csrf-token in POST request

Had the same issue for days and figured it out today:

You need to submit the session cookie, which you will find in the "set-cookie" header of your GET request.
This needs to be passed to the POST request. Unfornately this can't be done using a custom connector.
I used a normal http request for this. You can set a Cookie Attribute there.
For the info from "set-cookie" you need to replace "," with ";" before passing it to your POST-Request.
