There is no impact to Photonic. The user agent has been a part of the request for a few years now.
Thanks for the quick response. I’m glad to hear you are ahead of this change!
As it turns out, the Flickr team has retracted this initiative!
Dear valued community members,
We wanted to reach out to you to apologize for the recent announcement of a new requirement for requiring User-agents to API requests. We understand that this news may have caused concern and inconvenience, and we wanted to take a moment to address your feedback.
After careful consideration and review of your feedback, we have decided not to proceed with the launch of this requirement. We recognize that it would have had a significant impact on existing implementations and legacy systems. Our team had hoped that this requirement would have had a positive impact on our community, but we understand that it would have been too disruptive for many of our users.
We take responsibility for not fully understanding the impact of this requirement before announcing it, and we sincerely apologize for any confusion or disruption it may have caused. We are committed to listening to your feedback and doing our best to meet the needs of our community.
Once again, we apologize for any inconvenience caused, and we thank you for your understanding and continued support.
The Flickr Team
Yup – I received the email from them.
In any case, it doesn’t matter here. Basically, for a really long time I have been passing this parameter, so unless Flickr says that we are not supposed to send the parameter, there is no impact to Photonic.
