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.
Updated the image.Please look into it.Additionally if you face any issue viewing the attached image then you can find the error description in issue description part of the query posted.
Thanks.
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
How did u even get the Authentication token without redirect_uri?
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 !
