When you move off a previous partner portal, its links do not move with you. They sit in partner emails, in co-marketing pages, in sales decks and in browser bookmarks, and they point at a domain you are about to switch off. This guide keeps them working: you add one redirect rule at your old domain, and Introw catches every incoming link on your new portal domain and sends the visitor somewhere real.

​
What you’ll achieve

Every link minted by your old portal resolves on your Introw portal instead of a dead page, with the links that matter most landing on the exact Introw form they used to open.

​
Before you start

1

Have your Introw custom domain live first

The redirect lands on your Introw portal domain, so connect a custom domain and confirm it serves before you change anything at the old domain. Cutting over in the other order leaves the redirect with nowhere to go.
2

Keep control of the old domain

You need to be able to add a redirect rule at the old hostname, at your CDN or DNS provider. The old portal itself does not need to stay running.
3

Know which old links still matter

Pull the paths that are still in circulation, typically a referral or lead form, a sign-up page, and the portal root. You will hand this short list to Introw in the last step.

​
Steps

1

Redirect the old domain to /legacy

Add one wildcard rule at your old portal domain that forwards every path, preserving the path and the query string, to /legacy on your Introw domain:
One rule covers the whole domain. There is nothing per-partner and nothing per-link to maintain at your end, and no API key or token to rotate.
2

Check that a link lands

Open one of the old links in a browser. It should end up on your Introw portal rather than an error page. Introw recognises which portal the link belongs to from the domain it arrived on, which is why no configuration is needed to get this far.
3

Send Introw the paths that should land on a form

Anything Introw has not been told about lands on your portal home, which is a safe default but not the right one for a link that used to open a form. Send your Introw contact the path and the Introw form it should open, for example:Introw maps them, and those links then go straight to the form instead of the portal home.
4

Hand over the partner identifiers, if your old links carry them

Old links often name the partner who shared them, for example ?referralId=..., and that identifier is what keeps a submission attributed to the right partner. Check what the value actually is before assuming, because it decides whether there is any work left here at all.On Salesforce the first three characters of a record id name the object it belongs to: 001 is an Account, while an id starting a0 is a custom object such as a referral record. A name like referralId is not evidence either way, so read a real link rather than the parameter name.If the value is the account id of the partner, Introw already syncs that and matches it directly, and you send nothing. Otherwise, export the pairs of old identifier and partner account id and send them over.

​
Verify it worked

Follow a real old link end to end, not a hand-typed one. A mapped link opens the Introw form it should, with the partner already applied, so a submission arrives attributed rather than unassigned. An unmapped link opens your portal home. Campaign parameters such as utm_source survive the redirect in both cases, so reporting on links already in the wild stays intact.

​
Good to know

A link whose partner identifier matches nothing still opens the form, without the partner applied. On a public lead form that is deliberate: an unattributed submission can be reassigned in Introw afterwards, where an error page loses the lead entirely.
Redirects are not cached, so a correction to a mapping takes effect on the next click rather than waiting out a browser or CDN cache.
