External API Store redirect URL missing tenant query parameter for cross-tenant publishing

[PasanT9]

Description

Hi Team,

When publishing an API from one tenant's Developer Portal to another tenant's external Developer Portal using the external-api-stores.xml configuration, the "Visit Publisher Developer Portal" redirect link generated in the target tenant's Dev Portal is missing the ?tenant= query parameter.

This means regardless of what is configured in :

• devportal → produces devportal/apis/ — missing ?tenant=
• devportal/apis?tenant=domain (as shown in the official docs) → tenant param gets stripped by the split → still missing ?tenant=
• devportal?tenant=domain → no regex match, naive string concat → malformed URL devportal?tenant=domain/apis/

Steps to Reproduce

1. Start WSO2 API Manager 4.5.0
2. Create two tenants — e.g. tenant1.com (source) and tenant2.com (target)
3. Log in to the Carbon console (https://localhost:9443/carbon) as admin@tenant1.com
4. Navigate to Main → Registry → Browse → /_system/governance/apimgt/externalstores/external-api-stores.xml
5. Set the config as follows and save:

<ExternalAPIStores>
    <StoreURL>https://localhost:9443/devportal/apis?tenant=tenant1.com</StoreURL>
    <ExternalAPIStore id="Tenant2Portal" type="wso2" className="org.wso2.carbon.apimgt.impl.publishers.WSO2APIPublisher">
        <DisplayName>Tenant2 Portal</DisplayName>
        <Endpoint>https://localhost:9443/devportal/apis?tenant=tenant2.com</Endpoint>
        <Username>admin@tenant2.com</Username>
        <Password>admin123</Password>
    </ExternalAPIStore>
</ExternalAPIStores>

6. Log in to Publisher as admin@tenant1.com, create and publish an API
7. On the published API, go to External Developer Portals tab → select Tenant2 Portal → click Save
8. Log in to Dev Portal as admin@tenant2.com (https://localhost:9443/devportal?tenant=tenant2.com)
9. Find the published API and click Visit Publisher Developer Portal

Actual Result

Redirects to super tenant Dev Portal — wrong tenant context.

https://localhost:9443/devportal/apis?tenant=tenanat1.com/apis/<uuid>

---

Expected Result

https://localhost:9443/devportal/apis/<uuid>/overview?tenant=tenant1.com

Should redirect to the source tenant (tenant1.com) Dev Portal where the API can be subscribed to.
