HTTP Request "date" header error

Hi everyone!

I’m losing my mind because of an API integration. I’m trying to use an API to get a state about a sign operation. I send the ID of the document and the API gives me a number with the state. The thing is: I have tried with HTTP Request, using the headers I need, but I am given an error that says I haven’t sent the header “date” (this header has to be the actual datetime in milliseconds). But if I use POSTMAN to try an example, it works fine!

I use the same headers, everything is the same, but with HTTP Request it doesn’t work and I don’t know why. I have these headers:

This gives me an error documented on the website. But if I use Postman it works:

Do you know why this is happening? It’s the first time I’m using an API from a website without any help and I don’t know what to do. I have tried with invoke code, but without an example I can’t go on. When I send a document for signing I have to use an invoke code and I have this written in (maybe it helps):

Thank you so much for your help.

Had you tried to send the date as number / withoud enclosning "

Sometimes HTTP Request is limited. But when implementing custom call we would use nowadays HTTClient

Hi Peter,

Thank you for your reply. It doesn’t work as a number:

What is that HttpClient? Is that a new package I can use? I don’t see it as an activity.
