OnBeforeRequest/OnAfterRequest Help!

Hello everyone, 

I have been trying for quite some time to get a RESTapi to work, which needs to connect and disconnect from the API with each request. To do this, we need to add a Token ID to each request, obtained with the first request, and pass it in the Header.

After some research, I came to understand that I must go through the OnBeforeRequest/OnAfterRequest options... but I can't figure out how to pass my token in the header of subsequent requests.

Here is what I need to accomplish:

1. Login to API
2. The server return in body the access token :

“access_token”: “”,
“expires_in”: 3600,
“token_type”: “Bearer”,
“scope”: “api”

3. Add the token in the header of all the subsequent requests : Authorization : Bearer + access_token

4. Logout

Thank you for your help! 

Hi Kevin, 

Try to use the AddHeader built in server action from the HTTPRequestHandler module. I guess this should help.

Please let me know if this works...
