API Integration Key - Authorization

[dhwanit_shah3]

Hello Geeks,

I have an issue where i am trying to connect to API service which accepts SHA256 bit encrypted BAse64 string which should include API Key as well. I am using class "cl_abap_message_digest=>calculate_hash_for_char" - but this only converts URL that i am passing. Along with URL i still need to pass API Secret key provided by vendor which is "CPv3+fT6er!]yKvp". Vendor recommends this conversion from website "https://hash.online-convert.com/sha256-generator". However i need to this dynamically in the loop while i make each call. Can someone please help me find the Class or FM which can convert this for me?

Really appreciate your responses.

Thanks.

Hello Dhwanit,

Did you check the possibility of converting the base64 using CL_HTTP_UTILITY?

Cheers!

Hi Isuru,

Yes, i looked at that option. I think i found the solution. I am using class cl_abap_hmac now. This does give me the Authorization link i am getting.

Thanks - Dhwanit.
