How do I send a token to Backend service from Azure API manangement

Question

How do I pass a token to a backend service from API management with this policy? I have a C# azure function (http-trigger) that acts like an api, to access it users need to have a valid jwt token, I have that working fine. but I cannot seem to send the jwt token to the backend service.

<policies>
<inbound>
    <validate-jwt header-name="Authorization" failed-validation-httpcode="401" failed-validation-error-message="Unauthorized. Access token is missing or invalid.">
        <openid-config *******************************/>
        <audiences>
            <audience>***********************</audience>
        </audiences>
        <issuers>
            <issuer>******************</issuer>
        </issuers>
    </validate-jwt>
    <base />
</inbound>
<backend>
    <base />
</backend>
<outbound>
    <base />
</outbound>
<on-error>
    <base />
</on-error>

@codebrane I tried that, but it's still not sending the jwt to the back end — johnson dubula, Dec 06 '21 at 15:52

Have you considered forward-request to send your HTTP request to your backend service?

<backend>
  <forward-request />
</backend>

Could you provide some trace of your current implementation, @johnsondubula? – sschmeck Dec 08 '21 at 08:24
when I print the claims, these are the only two that are sent to the backend http://schemas.microsoft.com/2017/07/functions/claims/keyid apim-MyAPIManangement http://schemas.microsoft.com/2017/07/functions/claims/authlevel Function – johnson dubula Dec 08 '21 at 16:13

What worked was this

<value>@(context.Request.Headers.GetValueOrDefault("Authorization"))</value>

And where did you add that? That would be really helpful to know! – Nightking Aug 10 '22 at 11:22
