I am sending API requests to JIRA using JWT token authentication. I added the method (get, post, etc.) and the endpoint to SHA256 encoding. This succeeds:
qsh = Digest::SHA256.hexdigest("GET&#{endpoint}&")
jwt = JWT.encode({
qsh: qsh,
iat: issued_at,
exp: expires_at,
iss: key
}, secret)
However, I cannot add query parameters to the URI. If I append query parameters:
qsh = Digest::SHA256.hexdigest("GET&#{endpoint}&start=50&limit=50")
jwt = JWT.encode({
qsh: qsh,
iat: issued_at,
exp: expires_at,
iss: key
}, secret)
I receive unauthorized response 401.
