Hello,
I am working on a payment API that requires "Authentication: Bearer"
authentication. My libcurl code to retrieve the bearer token is working fine. The token
is passed to the header of an API call that submits a payment. The API is running on
AWS. I am sending the request via a proxy server.
I have a command-line version of the libcurl that is working just fine.
However, my C implementation is reliably generating a 403 Forbidden.
In my C implementation I have installed the "standard" debug.c machinery to match the
"--trace-ascii" output from the curl executable. I have put the traces up side-by-side
with the Beyond Compare tool and I see only one notable difference, which looks like the attached.
I apologize for the image, but it was the only way I could include pertinent information while
redacting sensitive material.
Your diff output only shows what is received, not the request: the
problem probably comes from what is in the request.
2 suggestions:
1) You post to this list the request contents diff (after having
obfuscated confidential data, of course): we need more information to
help you.
2) Use run your working curl command with additional argument --libcurl
<filename>: this will generate a file called <filename> containing a C
program skeleton corresponding to the submitted request. You can then
compare it to what you coded in your program.
