PostQueen uses Neynar as the Farcaster API provider.
You need a Neynar developer account to obtain the API credentials below.
Set up Farcaster
1
Create a Neynar app
Go to the Neynar dashboard and create a new app. You will get a Client ID and a Secret Key.
There is no redirect URI to set here, which is why this page has no callback block while
every other OAuth network does. Farcaster sign-in goes through Neynar’s widget, so PostQueen
hands it the client ID directly rather than building a callback path for the network to
return to.
2
Add credentials to your environment
Add the following to your
.env file:3
Restart PostQueen
Stop PostQueen if it is running and start it again so the new environment variables are picked up.
4
Add the channel
In the PostQueen web interface, click Add Channel, select Farcaster, and complete the Neynar login flow. Your Farcaster account will appear in the channel list.
The channel is in the left sidebar with its avatar and name. That is the whole confirmation: if it is in the list, she can post to it.
