I know everyone must be super busy with the rollout of the new Messenger Apps. I hope somebody still gets a chance to reply to my question It’s going to be huge and I am super excited to see this coming!
I am currently implementing the open-sheet flow and have a couple of questions around that:
I have problems decrypting the user. If you had any examples on how to do this in PHP ( > 7.1) it would be appreciated). Specifically how to get the IV and auth_tag.
The documentation doesn’t specify which you use for encryption. I have tried the “Identity verification Secret” as well as the “OAuth Client Secret”, but no luck.
It would actually be super helpful to have the user already available during the initialize flow.
Any help/insights would be appreciated.
