I'm currently using the https://firebase.google.com/docs/dynamic-links/rest to build short dynamic links from both long links and parameters.

Missing from this documentation is feature parity that exists on console, like attaching a custom suffix to your short url.

I have already discovered undocumented functionality, like the missing ofl fallback parameter as the following.

{
  desktopInfo: 
  {
   desktopFallbackLink: "https://getspar.com"
  }
}

After doing some digging i've found some references to a suffix option CUSTOM that is missing from the canonical resources. 

"suffix": { # Short Dynamic Link suffix. # Short Dynamic Link suffix. Optional.
      "option": "A String", # Suffix option.
      "customSuffix": "A String", # Only applies to Option.CUSTOM.
    },

https://developers.google.com/resources/api-libraries/documentation/firebasedynamiclinks/v1/python/latest/firebasedynamiclinks_v1.shortLinks.html

Also a mention of this in go autodocumentation as well https://godoc.org/google.golang.org/api/firebasedynamiclinks/v1#Suffix

However i'm getting

Unsupported Suffix option CUSTOM

My guess is it is in fact exposed, I just don't know the correct data structure. Anyone

  • Thanks very much for this, I has been looking for the ofl parameter for a long time now :) – Aston Jan 10 '20 at 13:22
  • Also via the console you can assign a name, cannot find a way to assign a name when the link is created via the REST API :c – ronnie bermejo Nov 19 '20 at 04:53
  • If someones find post in '21 this should work https://stackoverflow.com/questions/63381474/is-it-possible-to-specify-the-short-link-with-firebase-dynamic-links/70338441#70338441 – lisek Dec 13 '21 at 17:13

As I encounter this issue, I just find out that this feature is not available by using the REST API. Right now it is only working for the links created by the Firebase Console. That's why I think it is undocumented in REST API.
