After API V1 is retired in June, will users on old versions receive an error message?

[ElizabethW]

I'm working on migrating my app to API v2.  After API v1 is retired in June, what will happen to my users who do not install the updated version of my app?  Will they see an error message when running Dropbox related features?

My apologies if this question has been answered before, I searched and could not find any similar questions.

Thank you.

Hi Elizabeth, per the migration guide, when API v1 is retired in June 2017, any further API v1 calls will fail with a 400 error with the body:

{"error": "v1_retired"}

That is similar to other errors, and would be translated into error types in the SDKs. Exactly what would happen in your app would depend on the error handling built in to your app.

Hope this helps!

Hi Greg,

I have seen the notice of the v1_retired error you metioned, but I understand this is the HTTP version of this responce.

But what will happen to old mobile apps? using native core v1 SDK?

Will they be able to continue working with these SDKs?

i.e. will a user using an old iOS app version (with Dropbox's Obj-C CoreV1 SDK) link his account to the app. As in the:

[[DBSession sharedSession] linkFromController:viewController]

Thanx,

Amir

Hi Amir, any apps still using API v1 SDKs will no longer be able to successfully make API calls. Any further API v1 calls will fail with a 400, which the SDK will translate to its native error type.

The linkFromController method in particular may continue working to some extent since that isn't an API call made to the server exactly, but the resulting access token won't be useful anyway, since any subsequent API calls will fail anyway.

Thank you, this is very helpful.
