hi there, i need to create a rest call like the example below:

POST /auth/realms/edoc/protocol/openid-connect/token
Authorization: Basic abcdefghilmnopqrstuvz
Content-Type: application/x-www-form-urlencoded
grant_type=password&username=mario&password=XJp45pzH

i'm not sure if it's possible and how to set an authorization header HTTP Basic as requested using a client_id and a client_secret that i own

Here is part of the code i'm using which is missing the auth basic header as requested

httpclient http  
http = create httpclient 

ls_URL = ls_token_uri + '/auth/realms/edoc/protocol/openid-connect/token'
ls_mime = 'application/x-www-form-urlencoded'
ls_parm = 'grant_type=password&username=' + ls_username + '&password=' + ls_password
ls_url = ls_url + '?' + ls_parm

http.SetRequestHeader("Content-Type", ls_mime)
li_ret = http.sendrequest( 'POST', ls_url, '')  
if li_ret = 1 then
    li_rc = http.GetResponseStatusCode()
    if li_rc = 200 then http.GetResponseBody(ls_string)

    ...

any help would be appreciated
tia

i've finally managed how to handle this. Here is the solution in case someone else having same question

basically to set the http basic authorization i had to crypt the client_id and client_secret in base64 (i.e "client_id:client_secret")
then set a header like this

ls_header = 'Basic ' + ls_encoded
http.SetRequestHeader("Authorization", ls_header)

everything working fine

p.s. also i had to pass the parameters of the call in the body

2 things hear - can you explain how you converted to base64 



and also how do you pass the parameters of the call in the body

Hi Andrew

to pass the parameters in the body:



ls_parm = ls_response_type + '&' + ls_user + '&' + ls_pass

bdata = blob(ls_parm, EncodingUTF8!)

li_ret = ln_http.sendrequest( 'POST', ls_url, bdata) 



to encrypt any string in base64 you can look at this really useful Bcrypt object developed by Roland Smith
