OAuth2 Security

Secure API access with modern, token-based authentication.

Passwords and static API keys don’t scale well. OAuth2 Security provides a safer approach to authentication by using time-bound tokens and controlled access scopes — helping you protect integrations while keeping connectivity smooth.

The problem it solves

Legacy authentication methods introduce risk and operational pain:

• shared credentials across systems and teams

• long-lived API keys that are hard to rotate

• unclear access scope (“this key can do everything”)

• difficult offboarding when staff or vendors change

• limited visibility when access is misused

OAuth2 Security helps you lock things down without slowing integration work.

What OAuth2 Security does

Token-based authentication

Use short-lived access tokens rather than static credentials, reducing exposure if a token is ever compromised.

Scoped access

Limit what an integration can do by applying scopes/permissions, keeping access aligned with real use cases.

Safer rotation and lifecycle management

Token lifecycles support better security hygiene, including revocation and access control changes without broad disruption.

Better governance for integrations

OAuth2 supports more structured access patterns for internal apps, external services and partner tooling.

How it works

1) Authorise an application
An internal system or integration client requests access using OAuth2.

2) Issue an access token
XEDI grants a token based on configured permissions and rules.

3) Use the token for API calls
Requests are authenticated using the token rather than a password or static key.

4) Expire, refresh and revoke as needed
Tokens expire naturally and can be refreshed or revoked to maintain control.

Key benefits

• Stronger security posture: reduce reliance on static credentials

• Controlled access: limit integrations to only what they need

• Cleaner governance: simplify access management and offboarding

• Better operational safety: easier rotation and reduced credential sprawl

• Integration-friendly: supports modern API best practice

Best-fit use cases

• Businesses integrating multiple internal systems with XEDI

• Teams needing granular permissions for API access

• Organisations working with external developers or vendors

• Environments with audit, governance, or compliance requirements

• Companies scaling integrations and wanting safer access control

FAQ

Is OAuth2 replacing API keys entirely?
It depends on your setup. OAuth2 is ideal for modern token-based authentication and controlled access. Some environments still support keys for legacy use cases.

Can we restrict what an integration can access?
Yes — OAuth2 supports scoped permissions so clients only get the access they require.

What happens if a token is compromised?
Tokens are time-bound and can be revoked. Scoped access also limits potential impact compared to a broad static credential.

Does OAuth2 make integration harder?
Not typically. For many teams it’s more manageable than rotating shared keys, especially when multiple apps or environments are involved.
