Twitter callback URL length

[LindaJuffermans]

I’m unable to submit the callback URLs for the Twitter API because the form only allows 128 characters. How can I insert longer URLs?

This has now been increased. The alternative would be to change the way that your application listens for callbacks, potentially by including parameters of some form. You’ve not specified the length of callback that your application is currently using.

Our application is based on resources (i.e. components on a page) and the callback URL is generated based on the page and the location of the component on the page. Currently the longest URL I have found is 188 characters - what is the reason for having a length restriction anyway?

Our next issue is the amount of callback URLs seems to be limited to 10. Imagine 3 applications (2 web, 1 mobile) using the same twitter API key in 4 languages, that’s 12 callback URLs. Even worse for our testing - DEV, SIT and UAT means 36 callback URLs for the 3 applications in 4 languages (or 3 API keys).

Should I create a new topic?

[LindaJuffermans]

I got a request from one team to add 27 callback URLs… (in case you were wondering what the new limit should be)

This is useful feedback.

We currently have no plans to increase the number of callback URLs beyond 10 and we will improve our documentation to accommodate this. Other developers have implemented routing or alternative methods with parameters to handle this.

[LindaJuffermans]

If you’re not increasing the number of callbacks, would you consider allowing wildcards, globs or regex?

E.g. I like to believe that as long as the domain is whitelisted (something that we own and control), any path on the domain would be trusted.

We encourage you to manage/route multiple instances by using URL parameter values. For example:
http://mydomain.com/hello/there?variable=instance1
http://mydomain.com/hello/there?variable=instance2
etc.

These would all be handled by a single Callback URL with the form http://mydomain.com/hello/there
