I’ve been in contact with them over the past few weeks and currently they are not issuing any API keys for Lemmy projects until they “understand how content is currently being displayed and from there we can make decisions on further API requests”
This is the route I initially went and I kept getting Bad request signature. back when attempting to use the token. That's when I reached out to RedGIFs support.
I’ll give it another go but their support specifically told me that they haven’t authorised any Lemmy apps and I don’t want to step on any toes to potentially ruin a future relationship with them.
