How to calculate AWS Signature V4

Post by gyvillegas »

Hello,

I am working on a project that calls AWS APIs and as part of the Credentials we need to calculate and send Amazon Signature V4 from our IBMi. I am new calling APIs from IBMi and I was wondering if this is something that some of you are familiar with.
Thank you in advance for any help that you can provide.

Regards,
Yolanda

Hey! I'm sorry I just now saw this but we have been working with amazon APIs for a long while using RPG/IBMi systems. We have made great use of Scott's software and other handy techniques.

If you still need help feel free to reach out, as I've got a decent grasp on it at this point!

To calculate AWS Signature V4, you'll need to follow a specific set of steps involving hashing, encoding, and signing the request. The process can be a bit complex, but don't worry—I'm here to break it down for you.
Additionally, if you're looking to enhance your AWS skills, you might want to explore the top AWS certifications for 2023.
