The HTTP Allowlist option lets you register and verify external HTTP or HTTPS endpoints that can securely interact with the platform. Once verified, these endpoints can be used for workflows, integrations, callbacks, and delivery reporting.

The Verification Method section determines how ownership or access to the provided URL is validated before the endpoint is allowlisted.
Three verification methods are available:
Use DNS Verification when you have access to your domain’s DNS configuration.
When you select DNS Verification, the system generates a verification TXT record to confirm domain ownership.
Once the record is detected, the verification is completed automatically.
Use Web Token Verification when the endpoint can read query parameters and return the token value in the response.

When you select Web Token Verification, the platform sends a request to the specified endpoint with a fyno_token query parameter.
To complete verification, the endpoint must:
Once the returned token matches the generated token, the endpoint is verified successfully.
Once the token is validated, the endpoint is verified automatically.
Use this option when DNS or Web Token verification cannot be configured.

The provided URL is submitted for manual verification and approval by the Fyno team.
