Header is missing in HTTPS request reply API call

[ErikDM]

I'm sending a request with 4 Headers:

- Date: 2020-07-06T13:05:56Z

- Authorization: Bearer access token
- Accept: application/vnd.api+json

- Digest: SHA512(raw_payload)
- Signature: BASE64(RSA_SHA256_SIGN(PRIVATE_KEY,SIGNING_STRING))

But the target system does not receive my date-header that is required?

Is there anyone who can me help out here why this header is not sended???

Hi Sriprasad,

Thanks for your reply, but that is not the problem.

Step 1 = Building the Date Header

Step 2 = Request Reply

Message content in HTTPS request:

Unfortunately i get a response back that there is a missing mandatory header missing: Date

Hope someone can help me out here.

Regards,
Erik.
