Supported AWS regions for the AWS Partner Central Channel API - AWS Partner Central

Supported AWS regions for the AWS Partner Central Channel API

You can access the AWS Partner Central channel management service from any AWS commercial region with the following end point.

partnercentral-channel.global.api.aws

Signing requests with SigV4a

Because the AWS Partner Central Channel API uses a global endpoint, requests are signed with Signature Version 4a (SigV4a), an extension of SigV4 that supports signing with asymmetric cryptography, enabling signatures that are verifiable across multiple AWS Regions.

Using the AWS SDK or CLI

If you use an AWS SDK or the AWS CLI, SigV4a signing is handled automatically when you call the global endpoint. No additional configuration is required.

Signing requests manually

If you sign requests manually without an SDK, be aware of the following differences from standard SigV4:

  • SigV4a derives an Elliptic Curve Digital Signature Algorithm (ECDSA) keypair from your existing AWS secret access key, rather than using HMAC-based key derivation.

  • The credential scope uses * for the region component instead of a specific Region name, because the signature is valid across Regions.

For more information about how SigV4a works, see AWS Signature Version 4 for API requests. For code examples of SigV4a signing, see the sigv4a-signing-examples project on GitHub.
