RE: I am trying to use Restlet api using oauth 1.0 and i am getting this issue
Apologies – I’ve just been checking my facts and the order might not be too important in the header but it is certainly important when constructing the signature.
As next steps, I would recommend checking the Login Audit Trail:
Setup > Users/Roles > View Login Audit Trail – Make sure to add a column for “Detail”.
And checking that your signature generation code produces the expected result based on the example on this page:
