Problem in Facebook Integration with Pega PRPC
Hi,
Could anyone please help in generating authorization token while integrating Pega PRPC with facebook. I have tried with the below given URL but getting error.
{
"error": {
"message": "Invalid redirect_uri: Given URL is not permitted by the Application configuration",
"type": "OAuthException",
"code": 191
}
}
However, I was referring the given PDN article regarding integration with Facebook."https://pdn.pega.com/integration/how-to-post-updates-to-facebook-from-prpc" and followed the same approach.
PFA the error screen shot.

Accepted Solution
Two things:
1. I think the redirect_uri value is incorrect in your request. It doesn't match the URL you gave at the time of your Facebook app registration. To get the correct value of redirect_uri, login to https://developers.facebook.com/, navigate to your app by clicking My Apps link at the top. Click Settings on the left. You will find redirect_uri mentioned under Site URL field (see screenshot below).
2. You should always URL encode redirect_uri value. For example, in the above screenshot, my redirect_uri is https://foo.bar. So my authorization request should look like this:
Thanks for your guidance. I have generated the Authorization token from below given URL and it worked.
https://graph.facebook.com/oauth/access_token? client_id={CLIENTID}&client_secret={CLIENTSECRET}&grant_type=client_credentials
you will generally get it like this without redirect uri in url
{
"error": {
"message": "Missing redirect_uri parameter.",
Can you pleae check the screenshot "Authorization+code+error.PNG.png" - it appears to be microscopic when I try and view it !
